-name: automations
-description: Write ESPHome automation building blocks - triggers (on_* keys), actions and conditions. Use when adding or changing an on_* trigger, an action such as my_component.do_something, a condition, a callback registration method (add_on_*_callback), or code that calls build_callback_automation, build_automation, register_*_action or register_*_condition.
----
-
-# Automations: triggers, actions and conditions
-
-Automations have three building blocks: **Triggers** (fire when something happens), **Actions** (do
-something), and **Conditions** (check if something is true). The helpers named here are documented in
-their docstrings in `esphome/automation.py`.
-
-## Triggers: callback method (preferred)
-
-Use `build_callback_automation()` for simple triggers. This eliminates the need for a C++ Trigger class by
-using a lightweight pointer-sized forwarder struct registered directly as a callback. No `CONF_TRIGGER_ID`
-in the schema.
-
-**Python:**
-```python
-from esphome import automation
-
-CONFIG_SCHEMA = cv.Schema(
-    {
-        cv.GenerateID(): cv.declare_id(MyComponent),
-        cv.Optional(CONF_ON_STATE): automation.validate_automation({}),
-    }
-).extend(cv.COMPONENT_SCHEMA)
-
-
-async def to_code(config):
-    var = cg.new_Pvariable(config[CONF_ID])
-    await cg.register_component(var, config)
-    for conf in config.get(CONF_ON_STATE, []):
-        await automation.build_callback_automation(
-            var, "add_on_state_callback", [(bool, "x")], conf
-        )
-```
-
-`build_callback_automation` arguments: `parent`, `callback_method` (C++ method name), `args` (template args
-as `[(type, name)]` tuples), `config`, and optional `forwarder` (defaults to `TriggerForwarder<Ts...>`).
-
-For boolean filtering (e.g. `on_press`/`on_release`), use built-in forwarders with `args=[]`:
-```python
-for conf_key, forwarder in (
-    (CONF_ON_PRESS, automation.TriggerOnTrueForwarder),
-    (CONF_ON_RELEASE, automation.TriggerOnFalseForwarder),
-):
-    for conf in config.get(conf_key, []):
-        await automation.build_callback_automation(
-            var, "add_on_state_callback", [], conf, forwarder=forwarder
-        )
-```
-
-When the callback's parameters differ from the automation's arguments, or the trigger should only fire for
-some values, pass `params`, `forward` and `when`; the helper then generates a capture-less lambda (stored
-inline, nothing allocated). Name the parent with `automation.parent_ref(var)` and build `forward` from
-`MockObj` calls, not f-strings of C++:
-```python
-parent = automation.parent_ref(var)
-index = cg.RawExpression("index")
-await automation.build_callback_automation(
-    var,
-    "add_on_state_callback",
-    [(cg.StringRef, "x"), (cg.size_t, "i")],
-    conf,
-    params=[(cg.size_t, "index")],
-    forward=[cg.StringRef(parent.option_at(index)), index],
-)
-```
-`build_parent_callback_automation`, `build_trigger_callback`, `build_callback_automations` and
-`build_trigger_automations` cover the other shapes; see their docstrings in `esphome/automation.py`.
-
-**C++: no trigger class needed.** The callback registration method must be templatized to accept both
-`std::function` and lightweight forwarder structs (which avoid heap allocation):
-```cpp
-class MyComponent : public Component {
- public:
-  // Must be a template -- accepts both std::function and pointer-sized forwarder structs
-  template<typename F> void add_on_state_callback(F &&callback) {
-    this->state_callback_.add(std::forward<F>(callback));
-  }
- protected:
-  // Use CallbackManager when callbacks are always registered (e.g. core components)
-  CallbackManager<void(bool)> state_callback_;
-  // Use LazyCallbackManager when callbacks are often not registered -- saves 8 bytes
-  // (nullptr vs empty std::vector) per instance when no callbacks are added
-  // LazyCallbackManager<void(bool)> state_callback_;
-};
-```
-
-Never type a registration method's parameter as `std::function`; that forces a heap allocation for every
-forwarder struct:
-```cpp
-// Bad
-void add_on_state_callback(std::function<void(bool)> &&callback) {
-  this->state_callback_.add(std::move(callback));
-}
-```
-
-| Type | Idle overhead (32-bit) | When to use |
-|------|----------------------|-------------|
-| `CallbackManager<void(Ts...)>` | 12 bytes (empty `std::vector`) | Callbacks are always or almost always registered |
-| `LazyCallbackManager<void(Ts...)>` | 4 bytes (`nullptr`) | Callbacks are often not registered (common case) |
-
-Both live in `esphome/core/helpers.h` and accept `std::function`, lambdas and forwarder structs through
-their templatized `add()` method. `LazyCallbackManager` is a drop-in replacement for `CallbackManager` that defers allocation until the first
-callback is added. Prefer it for entity-level callbacks where most instances have no subscribers.
-
-## Triggers: Trigger class method
-
-Use `build_automation()` with a `Trigger<Ts...>` subclass only when the forwarder needs **mutable state
-beyond a single `Automation*` pointer** (e.g. edge detection tracking previous state, timing logic).
-
-**Python:**
-```python
-TurnOnTrigger = my_ns.class_("TurnOnTrigger", automation.Trigger.template())
-
-CONFIG_SCHEMA = cv.Schema(
-    {
-        cv.Optional(CONF_ON_TURN_ON): automation.validate_automation(
-            {cv.GenerateID(CONF_TRIGGER_ID): cv.declare_id(TurnOnTrigger)}
-        ),
-    }
-)
-
-
-async def to_code(config):
-    for conf in config.get(CONF_ON_TURN_ON, []):
-        trigger = cg.new_Pvariable(conf[CONF_TRIGGER_ID], var)
-        await automation.build_automation(trigger, [], conf)
-```
-
-**C++:**
-```cpp
-class TurnOnTrigger : public Trigger<> {
- public:
-  explicit TurnOnTrigger(MyComponent *parent) : last_on_{false} {
-    parent->add_on_state_callback([this](bool state) {
-      if (state && !this->last_on_)
-        this->trigger();
-      this->last_on_ = state;
-    });
-  }
- protected:
-  bool last_on_;
-};
-```
-
-## Actions
-
-```cpp
-template<typename... Ts> class MyAction : public Action<Ts...> {
- public:
-  explicit MyAction(MyComponent *parent) : parent_(parent) {}
-  void play(const Ts &...) override { this->parent_->do_something(); }
- protected:
-  MyComponent *parent_;
-};
-```
-Register it without writing a builder:
-```python
-automation.register_simple_action(
-    "my_component.do_something", MyAction, schema, synchronous=True
-)
-```
-The constructor receives the object named by `config[CONF_ID]`. Use `register_bare_action` for a
-no-argument constructor, `register_parented_action` for a class deriving from `Parented<T>`, and the
-`@automation.register_action(...)` decorator only when the builder must also set fields.
-
-Use `synchronous=True` for actions that run to completion inside `play()` without deferring. Use
-`synchronous=False` if the action may suspend/defer execution (e.g. `delay`, `wait_until`, `script.wait`)
-or store trigger arguments for later use.
-
-**Actions that only forward templatable values to their parent need no C++ class.** Register them with
-`register_apply_action`; do not write a `TEMPLATABLE_VALUE` class or a builder for this shape.
-```python
-automation.register_apply_action(
-    "my_component.set_gains",
-    schema,
-    automation.ApplyField(CONF_KP, "set_kp", cg.float_),
-    automation.ApplyField(CONF_KI, "set_ki", cg.float_),
-)
-```
-The `ApplyField`, `ApplyCall` and `register_apply_action` docstrings in `esphome/automation.py` cover the
-rest; `cover.control` and `cover.template.publish` are in-tree examples. An action whose input is a byte
-payload passes `automation.ApplyBytes(CONF_DATA, "send({})")` in the same call; a constant payload stays in
-flash and a lambda's vector is forwarded as data and size. `TEMPLATABLE_VALUE` with `cg.templatable` stays
-for actions whose `play()` has real logic beyond forwarding values.
-
-## Conditions
-
-```cpp
-template<typename... Ts> class MyCondition : public Condition<Ts...> {
- public:
-  explicit MyCondition(MyComponent *parent) : parent_(parent) {}
-  bool check(const Ts &...) override { return this->parent_->is_active(); }
- protected:
-  MyComponent *parent_;
-};
-```
-Register with `automation.register_simple_condition("my_component.is_active", MyCondition, schema)`;
-`register_bare_condition`, `register_parented_condition` and the decorator follow the action rules.
-
-**Conditions that only test their parent need no C++ class either.** Register them with
-`register_apply_condition`; the expression is applied to the parent, and an `ApplyCall` compares against
-config values.
-```python
-automation.register_apply_condition("my_component.is_active", schema, "is_active()")
-automation.register_apply_condition(
-    "my_component.state_is",
-    schema,
-    automation.ApplyCall("state == {}", ((CONF_STATE, cg.bool_),)),
-)
-```
-`cover.is_open`, `rtttl.is_playing` and `component.is_idle` are in-tree examples.

-# Public API and breaking changes
-
-Full policy: https://developers.esphome.io/contributing/code/#public-api-and-breaking-changes
-
-## What is public
-
-- **C++ in components:** only features documented at [esphome.io](https://esphome.io) are public API.
-  Undocumented `public` members are internal.
-- **C++ core and base classes** (`esphome/core/`, `Component`, `Sensor`, etc.): all `public` members are
-  public API.
-- **Components with global accessors** (`global_api_server`, etc.): all `public` members are public API
-  (except config setters).
-- **Python:** all documented configuration options are public API. Python code in `esphome/core/` that
-  existing core components use is stable API. Other Python code is internal unless explicitly documented
-  for external component use.
-- Changing the signature of a lambda that code generation injects is not a breaking change.
-
-## Policy
-
-- Aim for a **6-month deprecation window** when possible.
-- Clean breaks are allowed for signature changes, deep refactorings and resource constraints.
-- The migration path goes in the PR description (it generates the release notes).
-- A blog post is required for core/base class changes or significant architectural changes.
-
-Checklist:
-- [ ] Clear justification (RAM/flash savings, architectural improvement)
-- [ ] Explored non-breaking alternatives
-- [ ] Added deprecation warnings if possible (`ESPDEPRECATED` for C++)
-- [ ] Documented migration path in the PR description with before/after examples
-- [ ] Updated all internal usage and esphome.io
-- [ ] Tested backward compatibility during the deprecation period

-## Deprecating C++
-
-```cpp
-// Remove before 2026.6.0
-ESPDEPRECATED("Use new_method() instead. Removed in 2026.6.0", "2025.12.0")
-void old_method() { this->new_method(); }
-```
-
-## Deprecating config keys
-
-For a renamed key, use the shared `cv.rename_key` validator with `removed_in` (and `component` for
-context); it warns and migrates automatically:
-```python
-CONFIG_SCHEMA = cv.All(
-    cv.rename_key(
-        CONF_OLD_KEY, CONF_NEW_KEY, removed_in="2026.6.0", component="my_component"
-    ),
-    cv.Schema({...}),
-)
-```
-For other deprecations, warn manually during validation:
-```python
-# Remove before 2026.6.0
-if CONF_OLD_KEY in config:
-    _LOGGER.warning(
-        f"'{CONF_OLD_KEY}' deprecated, use '{CONF_NEW_KEY}'. Removed in 2026.6.0"
-    )
-    config[CONF_NEW_KEY] = config.pop(CONF_OLD_KEY)  # Auto-migrate
-```
-Cover the old syntax with a `validate.*.yaml` test (see the `component-tests` skill), and keep the language
-schema correct (see the `config-validation` skill).

-  `from esphome.components.my_component import DOMAIN`. Keep it in alphabetical order with the other
-  metadata constants. CI (`lint_component_domain`) fails without it.

-- `AUTO_LOAD`: components to automatically load. Not a way to put entities under the component's own key;
-  see "Entities of a hub" below.
-- `CONFLICTS_WITH`: incompatible components.
-- `CODEOWNERS`: GitHub usernames responsible for maintenance.
-- `MULTI_CONF`: whether multiple instances are allowed.
-
-## Basic pattern
-
-```python
-import esphome.codegen as cg
-import esphome.config_validation as cv
-from esphome.const import CONF_KEY, CONF_ID
-
-DOMAIN = "my_component"
-CONF_PARAM = "param"  # A constant that does not yet exist in esphome/const.py
-
-my_component_ns = cg.esphome_ns.namespace("my_component")
-MyComponent = my_component_ns.class_("MyComponent", cg.Component)
-
-CONFIG_SCHEMA = cv.Schema(
-    {
-        cv.GenerateID(): cv.declare_id(MyComponent),
-        cv.Required(CONF_KEY): cv.string,
-        cv.Optional(CONF_PARAM, default=42): cv.int_,
-    }
-).extend(cv.COMPONENT_SCHEMA)
-
-
-async def to_code(config):
-    var = cg.new_Pvariable(config[CONF_ID])
-    await cg.register_component(var, config)
-    cg.add(var.set_key(config[CONF_KEY]))
-    cg.add(var.set_param(config[CONF_PARAM]))
-```
-
-```cpp
-namespace esphome::my_component {
-
-class MyComponent : public Component {
- public:
-  void setup() override;
-  void loop() override;
-  void dump_config() override;
-
-  void set_key(const char *key) { this->key_ = StringRef(key); }
-  void set_param(int param) { this->param_ = param; }
-
- protected:
-  StringRef key_;
-  int param_{0};
-};
-
-}  // namespace esphome::my_component
-```
-
-When the setter takes the value unchanged, use `cg.add_optional(var.set_blah, config.get(CONF_BLAH))`; it
-is not awaited, and it skips only `None`, so `0` and `False` are still set. Required, invariant
-dependencies are constructor arguments to `cg.new_Pvariable()`, not setters.
-
-## Entity platforms
-
-**Sensor:**
-```python
-from esphome.components import sensor
-
-CONFIG_SCHEMA = sensor.sensor_schema(MySensor).extend(
-    cv.polling_component_schema("60s")
-)
-
-
-async def to_code(config):
-    var = await sensor.new_sensor(config)
-    await cg.register_component(var, config)
-```
-
-**Binary sensor:**
-```python
-from esphome.components import binary_sensor
-
-CONFIG_SCHEMA = binary_sensor.binary_sensor_schema().extend({...})
-
-
-async def to_code(config):
-    var = await binary_sensor.new_binary_sensor(config)
-```
-
-**Switch:**
-```python
-from esphome.components import switch
-
-CONFIG_SCHEMA = switch.switch_schema().extend({...})
-
-
-async def to_code(config):
-    var = await switch.new_switch(config)
-```
-
-## Entities of a hub
-
-A new component's entities go in platform files (`sensor.py`, `binary_sensor.py`, ...) that take the hub's
-id, never under the hub's own key with their platforms added to `AUTO_LOAD` to make that work. Auto loading
-a platform because the C++ uses its type is fine. See
-https://developers.esphome.io/architecture/components/#exposing-multiple-entities.
-```yaml
-# Bad - entities under the hub's key
-my_hub:
-  connected:
-    name: Connected
-
-# Good - the hub, then one platform entry that holds its entities
-my_hub:
-  id: hub1
-binary_sensor:
-  - platform: my_hub
-    my_hub_id: hub1  # optional with a single hub
-    connected:
-      name: Connected
-```
-
-**Optional child entities of a hub:** bind the config once with `sensor.sub_sensors(config)` (or
-`sub_binary_sensors`, `sub_text_sensors`, `sub_buttons`, `sub_switches`, `sub_numbers`, `sub_selects` in
-their domains), adding `parent=hub` for entities that derive from `Parented<T>`, then make one call per
-key, even when there is only one. A call creates the entity only when its key is configured, passes it to
-the setter and returns it (or `None`); extra arguments such as `min_value` or `options` go on the call.
-Always name the setter explicitly on the object that owns it, never with `getattr` and an f-string, and
-keep that variable short (`var` for the component itself, `hub` for one fetched with `cg.get_variable`) so
-the calls fit on one line. Loops whose setter also takes an index, such as `set_gate_threshold(x, n)`, stay
-as they are.
-```python
-# my_hub/sensor.py
-async def to_code(config):
-    hub = await cg.get_variable(config[CONF_MY_HUB_ID])
-    sensors = sensor.sub_sensors(config)
-    await sensors(CONF_TEMPERATURE, hub.set_temperature_sensor)
-    await sensors(CONF_HUMIDITY, hub.set_humidity_sensor)
-
-
-# my_hub/button.py
-async def to_code(config):
-    hub = await cg.get_variable(config[CONF_MY_HUB_ID])
-    buttons = button.sub_buttons(config, parent=hub)
-    await buttons(CONF_RESTART, hub.set_restart_button)
-```
-
-**Hub forwarding entities need no C++ class:** a button, switch, number or select that only calls its hub
-uses `button.ApplyButton` (`switch.ApplySwitch`, `number.ApplyNumber`, `select.ApplySelect`) in its schema
-and `apply=` on the `sub_*` call. The body is a call on the hub with `entity` and `state`, `value` or
-`index`/`option` in scope; on a switch, number or select `publish="before"` or `"after"` publishes the
-state. `publish="momentary"` is only for legacy action switches (restart, factory reset): it publishes off
-and runs the body only when turned on. Never use it for a new entity; an action is a button.
-```python
-switches = switch.sub_switches(config, parent=hub)
-await switches(CONF_BLUETOOTH, None, apply="set_bluetooth(state)", publish="after")
-```
-Restore an owned or standalone switch in `setup()` with `sw->restore()`, or `restore(default)` to still
-drive a state when the restore mode is disabled. A hub that applies its switches' restored states itself
-reads `sw->get_initial_write_state()`, which already applies `inverted`.
-
-**Entities that each watch a register field:** one class taking register, shift, mask and match from a
-Python tuple table, in typed `StaticVector`s sized by `cg.slot_counter`; not a template per bit, not a
-virtual listener base (a second vptr per entity).
-
-## Other helpers
-
-- **Pins and referenced components:** set them with `await cg.add_pin(var.set_cs_pin, config[CONF_CS_PIN])`
-  and `await cg.add_variable(var.set_bus, config[CONF_BUS_ID])`; both skip a `None` value, so pass
-  `config.get(KEY)` for an optional key, and return what they created. Use `cg.register_parented` for
-  `set_parent`.
-- `uart.new_uart_component(config, *ctor_args)` (and `i2c.new_i2c_component`, `spi.new_spi_component`,
-  `modbus.new_modbus_client_component`, `ble_client.new_ble_node_component`) constructs, registers and
-  attaches in one call.
-- `display.add_writer(var, config)` sets the lambda.
-- `MyEnum.options("on", prefix="MY_ENUM_")` builds an enum dict.
-- `button.restart_button_schema(cls)` (and `factory_reset_`, `query_`) are button presets.
-- `fv.get_declaring_config(id)` finds a hub's config in final validation.
-
-## State during code generation
-
-Use `CORE.data` for component state that needs to persist during configuration generation, namespaced
-under the component's `DOMAIN` and held in a `@dataclass`. Avoid module-level mutable globals: they
-persist between compilation runs if the host process (e.g. device-builder) doesn't fork/exec, whereas
-`CORE.data` is cleared between runs.
-
-```python
-from dataclasses import dataclass, field
-from esphome.core import CORE
-
-DOMAIN = "my_component"
-
-
-@dataclass
-class MyComponentData:
-    feature_enabled: bool = False
-    item_count: int = 0
-    items: list[str] = field(default_factory=list)
-
-
-def _get_data() -> MyComponentData:
-    if DOMAIN not in CORE.data:
-        CORE.data[DOMAIN] = MyComponentData()
-    return CORE.data[DOMAIN]
-
-
-def request_feature() -> None:
-    _get_data().feature_enabled = True
-```
-
-Don't use flat keys such as `CORE.data["my_component_feature"] = True`. Some components use `TypedDict`
-instead of a dataclass; both are acceptable.

-Run them with `script/test_build_components`. Use `-c <component>` to test specific components and
-`-t <target>` for specific platforms.
-
-- **Keep build-test variants few:** one `test.<platform>.yaml` per platform the code actually differs on.
-  A variant per board for platform-identical code only adds CI time.
-- **Config-only test files (`validate.*.yaml`):** use this prefix when a YAML file only needs to exercise
-  schema/validation paths and does not need to be compiled. CI runs `validate.*.yaml` files with
-  `esphome config` only and skips them during compile. The grammar mirrors `test.*.yaml`:
-  - `validate.<platform>.yaml`: base config-only test
-  - `validate-<variant>.<platform>.yaml`: config-only variant
-
-  Use this for deprecated-syntax migration tests, schema edge cases, or platform-specific validation
-  branches where building firmware adds no signal. A component may have any mix of `test.*.yaml` and
-  `validate.*.yaml` files. Validate files never participate in bus grouping; each one runs as its own
-  `esphome config` invocation.
-
-  When a PR's only edits to a component are `validate.*.yaml` files (no source changes, no `test.*.yaml`
-  changes, and the component isn't pulled in as a dependency of another changed component), CI skips the
-  compile stage for that component and only runs config validation. This is decided in
-  `script/determine-jobs.py` via `_component_change_is_validate_only` and surfaced as the
-  `validate_only_components` output that the `test-build-components-split` job consumes.
-
-## Grouping with packages
-
-Components that use shared bus packages can be grouped together in CI to reduce build count. **Never define
-buses (uart, i2c, spi, modbus) directly in test YAML files**; always use packages from
-`test_build_components/common/`.
-
-All includes in test files must go through dict-style `packages:` so that batch grouping works; the
-grouping scripts only understand dict-style packages. Never use list-style packages
-(`packages: [- !include ...]`) or top-level merge keys (`<<: !include common.yaml`). Bus packages are keyed
-by the bus name; the component's `common.yaml` is keyed by the component name (e.g.
-`cst328: !include common.yaml`):
-```yaml
-# test.esp32-idf.yaml - everything included via named packages
-packages:
-  uart: !include ../../test_build_components/common/uart_115200/esp32-idf.yaml
-  my_component: !include common.yaml
-```
-```yaml
-# common.yaml - component config only, NO bus definitions
-my_component:
-  id: my_instance
-
-sensor:
-  - platform: my_component
-    name: My Sensor
-```
-Components that define buses directly are flagged as "NEEDS MIGRATION" and cannot be grouped, increasing
-CI build time. `!extend` and `!remove` in a `test.*.yaml` also make the component ungroupable; add a
-standalone entity with its own id instead.
-
-A test that needs a shared component in a particular state (`esp32_ble` security settings, an option that
-PSRAM rejects) cannot be grouped: the merged block wins and the whole batch fails. Add the component to
-`ISOLATED_COMPONENTS` in `script/analyze_component_buses.py`, or move the option to a `test-<variant>` file.
-
-To verify that all components can be tested together without ID conflicts or configuration issues:
-```bash
-./script/test_component_grouping.py -e config --all
-```
-This tests all components in a single build to catch conflicts that might not appear when testing
-components individually. Use `-e config` for fast configuration validation, or `-e compile` for full
-compilation testing.

-description: Write or change ESPHome configuration validation - CONFIG_SCHEMA, cv.Schema, cv.typed_schema, custom validator functions, config keys and CONF_ constants, renamed or deprecated keys, and the language schema that script/build_language_schema.py extracts from them. Use whenever a change touches a component's schema or a validator in config_validation.py, automation.py or a component's .py files.

-# Configuration validation
-
-ESPHome validates YAML with `voluptuous` schemas built from `esphome/config_validation.py` (`cv`). The
-same schemas are also walked by `script/build_language_schema.py`, which produces the JSON language schema
-that editors and the dashboard use for completion and checking. A validation change is only finished when
-both still work.
-
-## Writing schemas
-
-- **Type hints:** validators are typed like any other function: `def validate_x(config: ConfigType) ->
-  ConfigType:`, with `ConfigType` imported from `esphome.types`.
-- **One schema per model:** when a component's options depend on a `model` key, use
-  `cv.typed_schema({...}, key=CONF_MODEL, default_type=...)` with each model's own keys and defaults, not
-  one schema plus a validator that rejects keys and fills defaults afterwards.
-- **Reuse existing validators:** before writing a custom validator, check for an existing one in
-  `config_validation.py` and compose it in `cv.All(...)` rather than duplicating logic across components.
-  For example, rename a config key with `cv.rename_key(CONF_OLD, CONF_NEW, removed_in="2026.6.0")`, and
-  reject mutually-exclusive keys with `cv.has_at_most_one_key(...)` / `cv.has_exactly_one_key(...)`. See
-  how `api` composes `cv.has_exactly_one_key` + `cv.rename_key`.
-- **Common validators:** `cv.int_`, `cv.float_`, `cv.string`, `cv.boolean`, `cv.int_range(min=0,
-  max=100)`, `cv.positive_int`, `cv.percentage`.
-- **Complex validation:** `cv.All(cv.string, cv.Length(min=1, max=50))`, `cv.Any(cv.int_, cv.string)`.
-- **Platform-specific:** `cv.only_on(["esp32", "esp8266"])`, `esp32.only_on_variant(...)`,
-  `cv.only_on_esp32`, `cv.only_on_esp8266`, `cv.only_on_rp2040`.
-- **Framework-specific:** `cv.only_with_framework(...)`, `cv.only_with_arduino`. On the ESP32, Arduino is
-  built as a component of ESP-IDF, so an ESP-IDF API, sdkconfig option or version floor is there on both
-  frameworks: gate on `esp32.require_idf_version(cv.Version(5, 5, 3), "psram_dma")`, which checks the
-  platform and the ESP-IDF under either framework, as `spi`, `usb_host` and `wifi` do. Reserve
-  `cv.only_with_framework("esp-idf")` for a build that has been tried on Arduino and fails there, and write
-  the actual failure next to it (`sendspin`: arduino-esp32 below ESP-IDF 6.0 bundles a second libsodium,
-  and from 6.0 sendspin-cpp's enumerators collide with `Arduino.h` macros such as `DISPLAY`).
-- **Schema extensions:**
-  ```python
-  CONFIG_SCHEMA = cv.Schema({ ... })
-   .extend(cv.COMPONENT_SCHEMA)
-   .extend(uart.UART_DEVICE_SCHEMA)
-   .extend(i2c.i2c_device_schema(0x48))
-   .extend(spi.spi_device_schema(cs_pin_required=True))
-  ```
-- **Constants:** `esphome/const.py` is frozen; do not add new `CONF_` constants there. Define a
-  component-local constant in the component's own `.py`; for a constant shared by multiple components, add
-  it to `esphome/components/const/__init__.py`. CI (`lint_constants_usage`) fails if the same constant is
-  defined in three or more component files. Constants used in core files (those not under
-  `esphome/components`) may be added to `esphome/const.py` but will require adjustment to the CI check.
-- **Renamed or removed keys:** see the `breaking-changes` skill for `cv.rename_key` and manual
-  deprecation warnings.
-- **Config-only tests:** schema edge cases and deprecated-syntax migrations go in `validate.*.yaml` test
-  files (see the `component-tests` skill).
-
-## Schema extraction
-
-`script/build_language_schema.py` sets `esphome.schema_extractors.EnableSchemaExtraction = True` before it
-imports any component, then walks every `CONFIG_SCHEMA` (and platform schema) recursively. It understands
-`cv.Schema`, `cv.All`, `cv.Any`, dicts of `cv.Required` / `cv.Optional` keys, `.extend()`, `cv.ensure_list`,
-`cv.typed_schema`, registries and the known `cv` validators. **A plain function it cannot see into**: a
-custom validator that builds or picks a schema at validation time hides every key behind it, and the
-dumper silently emits nothing for them. CI only runs the script with `--check`, which does not compare the
-output, so a lost schema is not caught.
-
-When a validator function wraps, chooses or builds a schema (rather than checking a single value), make it
-visible to the dumper:
-
-1. Decorate it with `@schema_extractor("<type>")` from `esphome.schema_extractors`.
-2. At the top of the function, return the data for that type when it is called with `SCHEMA_EXTRACT`
-   instead of a config value. Compare with `is` (`value is SCHEMA_EXTRACT`); older code uses `==`.
-
-```python
-from esphome.schema_extractors import SCHEMA_EXTRACT, schema_extractor
-
-
-@schema_extractor("schema")
-def _outgoing_connection_schema(config: ConfigType | None) -> ConfigType:
-    if config is SCHEMA_EXTRACT:
-        return _OUTGOING_CONNECTION_SCHEMA
-    if config is None:
-        config = {}
-    return _OUTGOING_CONNECTION_SCHEMA(config)
-```
-
-The type names the dumper accepts, and what `SCHEMA_EXTRACT` must return for each, are in the
-`hidden_schemas` branch of `convert()` in `script/build_language_schema.py`. The common ones:
-
-| Type | Return for `SCHEMA_EXTRACT` | Example |
-|------|-----------------------------|---------|
-| `"schema"` | the schema (or a representative one) to walk | `api` `_outgoing_connection_schema`, `restore_state_schema` in `esphome/core/entity_helpers.py`, `model_schema_extractor` in `esphome/components/mipi/__init__.py` |
-| `"enum"` | the dict of options | `sensor_entity_category` in `esphome/components/sensor/__init__.py` |
-| `"one_of"` | the list of options | `cv.one_of` |
-| `"maybe"` | `(validator, key)` for a scalar shorthand | `cv.maybe_simple_value`, `maybe_conf` in `esphome/automation.py` |
-| `"templatable"` | the inner validator | `cv.templatable` |
-| `"automation"` | the automation schema | `automation.validate_automation` |
-
-Points to watch:
-
-- The dumper matches the function object by `repr`, so the decorated function must be the exact object
-  placed in the schema. In a factory that returns a new closure per call, decorate the inner function (as
-  `restore_state_schema` and `cv.maybe_simple_value` do), not the factory.
-- The decorator only records anything when extraction is enabled, and that flag is set before imports, so
-  the decorator must run at import time (module level or inside a factory called at module level).
-- A schema chosen per config value (for example by `model`) has no single answer: return a representative
-  schema, as `model_schema_extractor` does.
-- Plain value checks (`cv.All(cv.string, my_check)`) need nothing: the dumper still sees the surrounding
-  types and keys.
-- `cv.Schema`, `cv.typed_schema`, `cv.ensure_list` and the `cv` helpers are already handled; prefer
-  composing them over a custom function, which also avoids the extractor work.
-
-### Checking the output
-
-Build the language schema into a scratch directory and look at the component's JSON (it takes about ten
-seconds):
-
-```bash
-python3 script/build_language_schema.py --output-path /tmp/schema
-python3 -c "import json; print(json.dumps(json.load(open('/tmp/schema/my_component.json')), indent=1))" | less
-```
-
-Every key a user can write should appear under `config_vars` with a sensible `type`; compare against the
-same output from `dev` when changing an existing schema. If the script prints `Unknown extracted schema
-type` or raises, the decorator type or the value returned for `SCHEMA_EXTRACT` is wrong. Unit tests for
-the dumper live in `tests/script/test_build_language_schema.py`.

-description: Choose ESPHome C++ containers and storage that avoid heap use and fragmentation on microcontrollers - std::array, StaticVector with cg.slot_counter, FixedVector, std::unique_ptr byte buffers, StringRef, RAMAllocator, and what to avoid (std::vector growth, std::map, std::deque, std::string, new (std::nothrow)). Use when adding or changing C++ members, containers, buffers, strings or registration lists, or when reducing RAM or flash use.

-
-# Memory on embedded targets
-
-ESP devices run for months with small heaps shared between Wi-Fi, BLE, LWIP, and application code. Over
-time, repeated allocations of different sizes fragment the heap. Failures happen when the largest
-contiguous block shrinks, even if total free heap is still large. We have seen field crashes caused by
-this.
-
-**Heap allocation after `setup()` should be avoided unless absolutely unavoidable.** Every
-allocation/deallocation cycle contributes to fragmentation. ESPHome treats runtime heap allocation as a
-long-term reliability bug, not a performance issue. Helpers that hide allocation (`std::string`,
-`std::to_string`, string-returning helpers) are being deprecated and replaced with buffer and view based
-APIs.
-
-## Container guidelines
-
-1. **Compile-time-known sizes:** use `std::array` instead of `std::vector` when size is known at compile
-   time.
-   ```cpp
-   // Bad - generates STL realloc code
-   std::vector<int> values;
-
-   // Good - no dynamic allocation
-   std::array<int, MAX_VALUES> values;
-   ```
-   Use `cg.add_define("MAX_VALUES", count)` to set the size from Python configuration.
-
-   **For byte buffers:** avoid `std::vector<uint8_t>` unless the buffer needs to grow. Use
-   `std::unique_ptr<uint8_t[]>` instead. It does **not** provide bounds checking or iterator support like
-   `std::vector<uint8_t>`; use it only when you do not need these features.
-   ```cpp
-   // Bad - STL overhead for simple byte buffer
-   std::vector<uint8_t> buffer;
-   buffer.resize(256);
-
-   // Good - minimal overhead, single allocation
-   std::unique_ptr<uint8_t[]> buffer = std::make_unique<uint8_t[]>(256);
-   // Or if size is constant:
-   std::array<uint8_t, 256> buffer;
-   ```
-
-2. **Compile-time-known fixed sizes with vector-like API:** use `StaticVector` from
-   `esphome/core/helpers.h` for compile-time fixed size with a `push_back()` interface (no dynamic
-   allocation).
-   ```cpp
-   // Bad - generates STL realloc code (_M_realloc_insert)
-   std::vector<ServiceRecord> services;
-   services.reserve(5);  // Still includes reallocation machinery
-
-   // Good - compile-time fixed size, no dynamic allocation
-   StaticVector<ServiceRecord, MAX_SERVICES> services;
-   services.push_back(record1);
-   ```
-   Use `cg.add_define("MAX_SERVICES", count)` to set the size from Python configuration.
-
-   **Listener and child-entity registration lists are the most common case, and the most commonly
-   missed.** A `register_*()` method called once per child at code generation time has a count that is
-   known at compile time, so it should never be a `std::vector`. Use `cg.slot_counter()`: it returns a
-   function that each consumer calls once per slot it will occupy, and after every `to_code` has run it
-   emits the define with the final count. When nothing registers, no define is emitted and the storage plus
-   its registration method compile out entirely.
-   ```python
-   # hub component's __init__.py
-   _request_listener_slot = cg.slot_counter("MY_COMPONENT_LISTENER_COUNT")
-
-
-   async def register_listener(hub: MockObj, var: MockObj) -> None:
-       _request_listener_slot()
-       cg.add(hub.register_listener(var))
-   ```
-   When several instances each own a list declared at the same size (one per hub of a `MULTI_CONF`
-   component), pass the owning object as the key, `_request_listener_slot(str(hub))`; the define is then
-   the largest count any one key requested instead of the total.
-   ```cpp
-   #ifdef MY_COMPONENT_LISTENER_COUNT
-     void register_listener(MyComponentListener *listener);
-   #endif
-    protected:
-   #ifdef MY_COMPONENT_LISTENER_COUNT
-     StaticVector<MyComponentListener *, MY_COMPONENT_LISTENER_COUNT> listeners_;
-   #endif
-   ```
-   Request slots from `to_code`, not from a job that runs after `CoroPriority.FINAL`; a late request
-   raises rather than silently undercounting.
-
-3. **Runtime-known sizes:** use `FixedVector` from `esphome/core/helpers.h` when the size is only known at
-   runtime initialization.
-   ```cpp
-   // Bad - generates STL realloc code (_M_realloc_insert)
-   std::vector<TxtRecord> txt_records;
-   txt_records.reserve(5);  // Still includes reallocation machinery
-
-   // Good - runtime size, single allocation, no reallocation machinery
-   FixedVector<TxtRecord> txt_records;
-   txt_records.init(record_count);  // Initialize with exact size at runtime
-   ```
-   This eliminates `_M_realloc_insert` and `_M_default_append` template instantiations (200-500 bytes per
-   instance), needs no upper bound, and is compatible with protobuf code generation when using
-   `[(fixed_vector) = true]`.
-
-4. **Small datasets (1-16 elements):** use `std::vector` or `std::array` with simple structs instead of
-   `std::map`/`std::set`/`std::unordered_map`.
-   ```cpp
-   // Bad - 2KB+ overhead for red-black tree/hash table
-   std::map<std::string, int> small_lookup;
-   std::unordered_map<int, std::string> tiny_map;
-
-   // Good - simple struct with linear search (std::vector is fine)
-   struct LookupEntry {
-     const char *key;
-     int value;
-   };
-   std::vector<LookupEntry> small_lookup = {
-     {"key1", 10},
-     {"key2", 20},
-     {"key3", 30},
-   };
-   // Or std::array if size is compile-time constant:
-   // std::array<LookupEntry, 3> small_lookup = {{ ... }};
-   ```
-   Linear search on small datasets is often faster than hashing or tree overhead, but this depends on
-   lookup frequency; in hot paths the O(1) vs O(n) difference may still matter. It is the heavy containers
-   (`map`, `set`, `unordered_map`) that should be avoided for small datasets unless profiling shows
-   otherwise.
-
-5. **Strings set once from configuration:** use `StringRef` (`esphome/core/string_ref.h`) rather than
-   `std::string`. Code generation passes a string literal that lives in flash for the life of the program,
-   so storing a `std::string` copies it onto the heap for nothing. `StringRef` is a non-owning pointer plus
-   length; it does not copy, and it must only ever refer to storage that outlives it (a string literal, or
-   a buffer owned elsewhere).
-   ```cpp
-   // Bad - heap copy of a literal that is already in flash
-   void set_keys(std::string keys) { this->keys_ = std::move(keys); }
-   std::string keys_;
-   ```
-   ```cpp
-   // Good - no allocation
-   void set_keys(const char *keys) { this->keys_ = StringRef(keys); }
-   StringRef keys_;
-   ```
-
-6. **Avoid `std::deque`:** it allocates in 512-byte blocks regardless of element size, guaranteeing at
-   least 512 bytes of RAM usage immediately. This is a major source of crashes on memory-constrained
-   devices.
-
-7. **Never use `new (std::nothrow)`:** on ESP-IDF exceptions are disabled, so a failed nothrow allocation
-   aborts instead of returning `nullptr`. Use `RAMAllocator` from `esphome/core/helpers.h`; CI rejects
-   `std::nothrow`.
-
-8. **Detection:** look for these patterns in compiler output:
-   - Large code sections with STL symbols (vector, map, set)
-   - `alloc`, `realloc`, `dealloc` in symbol names
-   - `_M_realloc_insert`, `_M_default_append` (vector reallocation)
-   - Red-black tree code (`rb_tree`, `_Rb_tree`)
-   - Hash table infrastructure (`unordered_map`, `hash`)
-
-Callback storage (`CallbackManager` vs `LazyCallbackManager`) and templated registration methods are
-covered in the `automations` skill.
-
-## Where to spend effort
-
-Prioritize container optimization for core components (API, network, logger), widely used components
-(mdns, wifi, ble), and components causing flash size complaints. Avoiding heap allocation after `setup()`
-is always required regardless of component type; the priority list is about effort spent on container
-migration (e.g. `std::vector` to `StaticVector`).

+        - `DOMAIN`: Required in every component's `__init__.py`, set to the component's own name as a plain
+          string (e.g. `DOMAIN = "my_component"`). Other code refers to the component through it, e.g.
+          `from esphome.components.my_component import DOMAIN`. Keep it in alphabetical order with the other
+          metadata constants. CI (`lint_component_domain`) fails without it.
+        - `DEPENDENCIES`: List of required components
+        - `AUTO_LOAD`: Components to automatically load. Not a way to put entities under the component's
+          own key; see "Entities of a hub" below.
+        - `CONFLICTS_WITH`: Incompatible components
+        - `CODEOWNERS`: GitHub usernames responsible for maintenance
+        - `MULTI_CONF`: Whether multiple instances are allowed
+
+*   **Code Generation & Common Patterns:**
+    *   **Configuration Schema Pattern:**
+        ```python
+        import esphome.codegen as cg
+        import esphome.config_validation as cv
+        from esphome.const import CONF_KEY, CONF_ID
+
+        DOMAIN = "my_component"
+        CONF_PARAM = "param"  # A constant that does not yet exist in esphome/const.py
+
+        my_component_ns = cg.esphome_ns.namespace("my_component")
+        MyComponent = my_component_ns.class_("MyComponent", cg.Component)
+
+        CONFIG_SCHEMA = cv.Schema(
+            {
+                cv.GenerateID(): cv.declare_id(MyComponent),
+                cv.Required(CONF_KEY): cv.string,
+                cv.Optional(CONF_PARAM, default=42): cv.int_,
+            }
+        ).extend(cv.COMPONENT_SCHEMA)
+
+
+        async def to_code(config):
+            var = cg.new_Pvariable(config[CONF_ID])
+            await cg.register_component(var, config)
+            cg.add(var.set_key(config[CONF_KEY]))
+            cg.add(var.set_param(config[CONF_PARAM]))
+        ```
+
+    *   **C++ Class Pattern:**
+        ```cpp
+        namespace esphome::my_component {
+
+        class MyComponent : public Component {
+         public:
+          void setup() override;
+          void loop() override;
+          void dump_config() override;
+
+          void set_key(const std::string &key) { this->key_ = key; }
+          void set_param(int param) { this->param_ = param; }
+
+         protected:
+          std::string key_;
+          int param_{0};
+        };
+
+        }  // namespace esphome::my_component
+        ```
+
+    *   **Common Component Examples:**
+        - **Sensor:**
+          ```python
+          from esphome.components import sensor
+
+          CONFIG_SCHEMA = sensor.sensor_schema(MySensor).extend(
+              cv.polling_component_schema("60s")
+          )
+
+
+          async def to_code(config):
+              var = await sensor.new_sensor(config)
+              await cg.register_component(var, config)
+          ```
+
+        - **Binary Sensor:**
+          ```python
+          from esphome.components import binary_sensor
+
+          CONFIG_SCHEMA = binary_sensor.binary_sensor_schema().extend({...})
+
+
+          async def to_code(config):
+              var = await binary_sensor.new_binary_sensor(config)
+          ```
+
+        - **Switch:**
+          ```python
+          from esphome.components import switch
+
+          CONFIG_SCHEMA = switch.switch_schema().extend({...})
+
+
+          async def to_code(config):
+              var = await switch.new_switch(config)
+          ```
+
+        - **Entities of a hub:** a new component's entities go in platform files (`sensor.py`,
+          `binary_sensor.py`, ...) that take the hub's id, never under the hub's own key with their platforms
+          added to `AUTO_LOAD` to make that work. Auto loading a platform because the C++ uses its type is
+          fine. See https://developers.esphome.io/architecture/components/#exposing-multiple-entities.
+          ```yaml
+          # Bad - entities under the hub's key
+          my_hub:
+            connected:
+              name: Connected
+
+          # Good - the hub, then one platform entry that holds its entities
+          my_hub:
+            id: hub1
+          binary_sensor:
+            - platform: my_hub
+              my_hub_id: hub1  # optional with a single hub
+              connected:
+                name: Connected
+          ```
+
+        - **Optional child entities of a hub:** bind the config once with `sensor.sub_sensors(config)` (or
+          `sub_binary_sensors`, `sub_text_sensors`, `sub_buttons`, `sub_switches`, `sub_numbers`,
+          `sub_selects` in their domains), adding `parent=hub` for entities that derive from `Parented<T>`,
+          then make one call per key, even when there is only one. A call creates the entity only when its key
+          is configured, passes it to the setter and returns it (or `None`); extra arguments such as
+          `min_value` or `options` go on the call. Always name the setter explicitly on the object that owns
+          it, never with `getattr` and an f-string, and keep that variable short (`var` for the component
+          itself, `hub` for one fetched with `cg.get_variable`) so the calls fit on one line. Loops whose
+          setter also takes an index, such as `set_gate_threshold(x, n)`, stay as they are.
+          ```python
+          # my_hub/sensor.py
+          async def to_code(config):
+              hub = await cg.get_variable(config[CONF_MY_HUB_ID])
+              sensors = sensor.sub_sensors(config)
+              await sensors(CONF_TEMPERATURE, hub.set_temperature_sensor)
+              await sensors(CONF_HUMIDITY, hub.set_humidity_sensor)
+
+
+          # my_hub/button.py
+          async def to_code(config):
+              hub = await cg.get_variable(config[CONF_MY_HUB_ID])
+              buttons = button.sub_buttons(config, parent=hub)
+              await buttons(CONF_RESTART, hub.set_restart_button)
+          ```
+
+        - **Pins and referenced components:** set them with `await cg.add_pin(var.set_cs_pin, config[CONF_CS_PIN])`
+          and `await cg.add_variable(var.set_bus, config[CONF_BUS_ID])`; both skip a `None` value, so pass
+          `config.get(KEY)` for an optional key, and return what they created. Use `cg.register_parented` for `set_parent`.
+
+        - **Hub forwarding entities need no C++ class:** a button, switch, number or select that only calls its hub
+          uses `button.ApplyButton` (`switch.ApplySwitch`, `number.ApplyNumber`, `select.ApplySelect`) in its schema
+          and `apply=` on the `sub_*` call. The body is a call on the hub with `entity` and `state`, `value` or
+          `index`/`option` in scope; on a switch, number or select `publish="before"` or `"after"` publishes the state.
+          `publish="momentary"` is only for legacy action switches (restart, factory reset): it publishes off and runs
+          the body only when turned on. Never use it for a new entity; an action is a button.
+          ```python
+          switches = switch.sub_switches(config, parent=hub)
+          await switches(CONF_BLUETOOTH, None, apply="set_bluetooth(state)", publish="after")
+          ```
+          Restore an owned or standalone switch in `setup()` with `sw->restore()`, or `restore(default)`
+          to still drive a state when the restore mode is disabled.
+          A hub that applies its switches' restored states itself reads `sw->get_initial_write_state()`, which
+          already applies `inverted`.
+
+        - **Other codegen helpers:** `uart.new_uart_component(config, *ctor_args)` (and `i2c.new_i2c_component`,
+          `spi.new_spi_component`, `modbus.new_modbus_client_component`, `ble_client.new_ble_node_component`)
+          constructs, registers and attaches in one call; `display.add_writer(var, config)` sets the lambda;
+          `MyEnum.options("on", prefix="MY_ENUM_")` builds an enum dict; `button.restart_button_schema(cls)` (and
+          `factory_reset_`, `query_`) are button presets; `fv.get_declaring_config(id)` finds a hub's config in
+          final validation.
+
+*   **Automations (Triggers, Actions, Conditions):**
+
+    Automations have three building blocks: **Triggers** (fire when something happens), **Actions** (do something), and **Conditions** (check if something is true).
+
+    *   **Triggers -- Callback method (preferred):**
+
+        Use `build_callback_automation()` for simple triggers. This eliminates the need for a C++ Trigger class by using a lightweight pointer-sized forwarder struct registered directly as a callback. No `CONF_TRIGGER_ID` in the schema.
+
+        **Python:**
+        ```python
+        from esphome import automation
+
+        CONFIG_SCHEMA = cv.Schema(
+            {
+                cv.GenerateID(): cv.declare_id(MyComponent),
+                cv.Optional(CONF_ON_STATE): automation.validate_automation({}),
+            }
+        ).extend(cv.COMPONENT_SCHEMA)
+
+
+        async def to_code(config):
+            var = cg.new_Pvariable(config[CONF_ID])
+            await cg.register_component(var, config)
+            for conf in config.get(CONF_ON_STATE, []):
+                await automation.build_callback_automation(
+                    var, "add_on_state_callback", [(bool, "x")], conf
+                )
+        ```
+
+        `build_callback_automation` arguments: `parent`, `callback_method` (C++ method name), `args` (template args as `[(type, name)]` tuples), `config`, and optional `forwarder` (defaults to `TriggerForwarder<Ts...>`).
+
+        For boolean filtering (e.g. `on_press`/`on_release`), use built-in forwarders with `args=[]`:
+        ```python
+        for conf_key, forwarder in (
+            (CONF_ON_PRESS, automation.TriggerOnTrueForwarder),
+            (CONF_ON_RELEASE, automation.TriggerOnFalseForwarder),
+        ):
+            for conf in config.get(conf_key, []):
+                await automation.build_callback_automation(
+                    var, "add_on_state_callback", [], conf, forwarder=forwarder
+                )
+        ```
+
+        When the callback's parameters differ from the automation's arguments, or the trigger should only
+        fire for some values, pass `params`, `forward` and `when`; the helper then generates a capture-less
+        lambda (stored inline, nothing allocated). Name the parent with `automation.parent_ref(var)` and build
+        `forward` from `MockObj` calls, not f-strings of C++:
+        ```python
+        parent = automation.parent_ref(var)
+        index = cg.RawExpression("index")
+        await automation.build_callback_automation(
+            var,
+            "add_on_state_callback",
+            [(cg.StringRef, "x"), (cg.size_t, "i")],
+            conf,
+            params=[(cg.size_t, "index")],
+            forward=[cg.StringRef(parent.option_at(index)), index],
+        )
+        ```
+        `build_parent_callback_automation`, `build_trigger_callback`, `build_callback_automations` and
+        `build_trigger_automations` cover the other shapes; see their docstrings in `esphome/automation.py`.
+
+        **C++ -- no trigger class needed.** The callback registration method must be templatized to accept both `std::function` and lightweight forwarder structs (which avoid heap allocation):
+        ```cpp
+        class MyComponent : public Component {
+         public:
+          // Must be a template -- accepts both std::function and pointer-sized forwarder structs
+          template<typename F> void add_on_state_callback(F &&callback) {
+            this->state_callback_.add(std::forward<F>(callback));
+          }
+         protected:
+          // Use CallbackManager when callbacks are always registered (e.g. core components)
+          CallbackManager<void(bool)> state_callback_;
+          // Use LazyCallbackManager when callbacks are often not registered -- saves 8 bytes
+          // (nullptr vs empty std::vector) per instance when no callbacks are added
+          // LazyCallbackManager<void(bool)> state_callback_;
+        };
+        ```
+
+    *   **Triggers -- Trigger class method:**
+
+        Use `build_automation()` with a `Trigger<Ts...>` subclass only when the forwarder needs **mutable state beyond a single `Automation*` pointer** (e.g. edge detection tracking previous state, timing logic).
+
+        **Python:**
+        ```python
+        TurnOnTrigger = my_ns.class_("TurnOnTrigger", automation.Trigger.template())
+
+        CONFIG_SCHEMA = cv.Schema(
+            {
+                cv.Optional(CONF_ON_TURN_ON): automation.validate_automation(
+                    {cv.GenerateID(CONF_TRIGGER_ID): cv.declare_id(TurnOnTrigger)}
+                ),
+            }
+        )
+
+
+        async def to_code(config):
+            for conf in config.get(CONF_ON_TURN_ON, []):
+                trigger = cg.new_Pvariable(conf[CONF_TRIGGER_ID], var)
+                await automation.build_automation(trigger, [], conf)
+        ```
+
+        **C++:**
+        ```cpp
+        class TurnOnTrigger : public Trigger<> {
+         public:
+          explicit TurnOnTrigger(MyComponent *parent) : last_on_{false} {
+            parent->add_on_state_callback([this](bool state) {
+              if (state && !this->last_on_)
+                this->trigger();
+              this->last_on_ = state;
+            });
+          }
+         protected:
+          bool last_on_;
+        };
+        ```
+
+    *   **Actions:**
+        ```cpp
+        template<typename... Ts> class MyAction : public Action<Ts...> {
+         public:
+          explicit MyAction(MyComponent *parent) : parent_(parent) {}
+          void play(const Ts &...) override { this->parent_->do_something(); }
+         protected:
+          MyComponent *parent_;
+        };
+        ```
+        Register it without writing a builder:
+        ```python
+        automation.register_simple_action(
+            "my_component.do_something", MyAction, schema, synchronous=True
+        )

+        The constructor receives the object named by `config[CONF_ID]`. Use `register_bare_action` for a
+        no-argument constructor, `register_parented_action` for a class deriving from `Parented<T>`, and
+        the `@automation.register_action(...)` decorator only when the builder must also set fields.
+
+        Use `synchronous=True` for actions that run to completion inside `play()` without deferring. Use `synchronous=False` if the action may suspend/defer execution (e.g. `delay`, `wait_until`, `script.wait`) or store trigger arguments for later use.
+
+        **Actions that only forward templatable values to their parent need no C++ class.** Register them
+        with `register_apply_action`; do not write a `TEMPLATABLE_VALUE` class or a builder for this shape.
+        ```python
+        automation.register_apply_action(
+            "my_component.set_gains",
+            schema,
+            automation.ApplyField(CONF_KP, "set_kp", cg.float_),
+            automation.ApplyField(CONF_KI, "set_ki", cg.float_),
+        )
+        ```
+        The `ApplyField`, `ApplyCall` and `register_apply_action` docstrings in `esphome/automation.py` cover
+        the rest; `cover.control` and `cover.template.publish` are in-tree examples. An action whose input is a
+        byte payload passes `automation.ApplyBytes(CONF_DATA, "send({})")` in the same call; a constant payload
+        stays in flash and a lambda's vector is forwarded as data and size. `TEMPLATABLE_VALUE` with
+        `cg.templatable` stays for actions whose `play()` has real logic beyond forwarding values.
+
+    *   **Conditions:**
+        ```cpp
+        template<typename... Ts> class MyCondition : public Condition<Ts...> {
+         public:
+          explicit MyCondition(MyComponent *parent) : parent_(parent) {}
+          bool check(const Ts &...) override { return this->parent_->is_active(); }
+         protected:
+          MyComponent *parent_;
+        };
+        ```
+        Register with `automation.register_simple_condition("my_component.is_active", MyCondition, schema)`;
+        `register_bare_condition`, `register_parented_condition` and the decorator follow the action rules.
+
+        **Conditions that only test their parent need no C++ class either.** Register them with
+        `register_apply_condition`; the expression is applied to the parent, and an `ApplyCall` compares
+        against config values.
+        ```python
+        automation.register_apply_condition("my_component.is_active", schema, "is_active()")
+        automation.register_apply_condition(
+            "my_component.state_is",
+            schema,
+            automation.ApplyCall("state == {}", ((CONF_STATE, cg.bool_),)),
+        )
+        ```
+        `cover.is_open`, `rtttl.is_playing` and `component.is_idle` are in-tree examples.
 
 *   **Type Hints:** Type-hint all function signatures, including test functions and config validators (e.g. `def validate_x(config: ConfigType) -> ConfigType:`, `def test_x() -> None:`). Import `ConfigType` from `esphome.types`.
     An intentionally empty body (an unused `register_dumper` builder, for example) gets a one-line docstring, not `pass`.
 
-*   **Configuration Validation:** follow the `config-validation` skill. In short: one `cv.typed_schema` per
-    model, reuse validators from `config_validation.py`, and never add `CONF_` constants to the frozen
-    `esphome/const.py`.
-    *   **Schema extraction:** whenever config validation code is added or changed, make sure
-        `script/build_language_schema.py` still extracts the full schema. The dumper cannot see inside a plain
-        function, so a validator function that wraps, chooses or builds a schema must be decorated with
-        `@schema_extractor(...)` and return the schema data when called with `SCHEMA_EXTRACT` (both from
-        `esphome.schema_extractors`). CI does not catch a missing schema; build the schema and check the
-        component's JSON as the `config-validation` skill describes.
+*   **Configuration Validation:**
+    *   **One schema per model:** when a component's options depend on a `model` key, use `cv.typed_schema({...},
+        key=CONF_MODEL, default_type=...)` with each model's own keys and defaults, not one schema plus a validator
+        that rejects keys and fills defaults afterwards.
+    *   **Reuse existing validators:** Before writing a custom validator, check for an existing one in `config_validation.py` and compose it in `cv.All(...)` rather than duplicating logic across components. For example, rename a config key with `cv.rename_key(CONF_OLD, CONF_NEW, removed_in="2026.6.0")`, and reject mutually-exclusive keys with `cv.has_at_most_one_key(...)` / `cv.has_exactly_one_key(...)`. See how `api` composes `cv.has_exactly_one_key` + `cv.rename_key`.
+    *   **Common Validators:** `cv.int_`, `cv.float_`, `cv.string`, `cv.boolean`, `cv.int_range(min=0, max=100)`, `cv.positive_int`, `cv.percentage`.
+    *   **Complex Validation:** `cv.All(cv.string, cv.Length(min=1, max=50))`, `cv.Any(cv.int_, cv.string)`.
+    *   **Platform-Specific:** `cv.only_on(["esp32", "esp8266"])`, `esp32.only_on_variant(...)`, `cv.only_on_esp32`, `cv.only_on_esp8266`, `cv.only_on_rp2040`.
+    *   **Framework-Specific:** `cv.only_with_framework(...)`, `cv.only_with_arduino`. On the ESP32, Arduino is
+        built as a component of ESP-IDF, so an ESP-IDF API, sdkconfig option or version floor is there on both
+        frameworks: gate on `esp32.require_idf_version(cv.Version(5, 5, 3), "psram_dma")`, which checks the
+        platform and the ESP-IDF under either framework, as `spi`, `usb_host` and `wifi` do. Reserve
+        `cv.only_with_framework("esp-idf")` for a build that has been tried on Arduino and fails there, and write
+        the actual failure next to it (`sendspin`: arduino-esp32 below ESP-IDF 6.0 bundles a second libsodium,
+        and from 6.0 sendspin-cpp's enumerators collide with `Arduino.h` macros such as `DISPLAY`).
+    *   **Schema Extensions:**
+        ```python
+        CONFIG_SCHEMA = cv.Schema({ ... })
+         .extend(cv.COMPONENT_SCHEMA)
+         .extend(uart.UART_DEVICE_SCHEMA)
+         .extend(i2c.i2c_device_schema(0x48))
+         .extend(spi.spi_device_schema(cs_pin_required=True))
+        ```
+    *   **Constants:** `esphome/const.py` is frozen — do not add new `CONF_` constants there. Define a component-local constant in the component's own `.py` (as with `CONF_PARAM` above); for a constant shared by multiple components, add it to `esphome/components/const/__init__.py`. CI (`lint_constants_usage`) fails if the same constant is defined in three or more component files. Constants used in core files (i.e. those not under `esphome/components`) may be added to `esphome/const.py` but will require adjustment to the CI validation check.

 *   **Testing:**
     *   **Python:** Run unit tests with `pytest`.
     *   **C++:** Use `clang-tidy` for static analysis.

+        with `LoopBlockingGuard{nullptr, nullptr, now_ms}`; the runner resets it before every test.
+    *   **Integration tests:** `tests/integration/` runs real firmware on the host. Serial components prove
+        timeouts and recovery with the `uart_mock` fixture (`tests/integration/test_uart_mock_*.py`). Its
+        `responses` match on content every time they see it; to answer a repeated request differently, use an
+        `on_tx` lambda with a static counter and `inject_to_rx_buffer` (see `uart_mock_ld2412_requery_after_giveup.yaml`).
+    *   **Keep build-test variants few:** one `test.<platform>.yaml` per platform the code actually differs
+        on. A variant per board for platform-identical code only adds CI time.
+    *   **A test that needs a shared component in a particular state** (`esp32_ble` security settings, an option
+        that PSRAM rejects) cannot be grouped: the merged block wins and the whole batch fails. Add the component to
+        `ISOLATED_COMPONENTS` in `script/analyze_component_buses.py`, or move the option to a `test-<variant>` file.
+    *   **Component Tests:** YAML-based compilation tests are located in `tests/`. The structure is as follows:
+        ```
+        tests/
+        ├── test_build_components/
+        │   └── common/          # Shared bus packages (uart, i2c, spi, etc.)

+        ```
+        Run them using `script/test_build_components`. Use `-c <component>` to test specific components and `-t <target>` for specific platforms.
 
+    *   **Config-only test files (`validate.*.yaml`):** Use this prefix when a YAML file only needs to exercise schema/validation paths and does not need to be compiled. CI runs `validate.*.yaml` files with `esphome config` only and skips them during compile. The grammar mirrors `test.*.yaml`:
+        - `validate.<platform>.yaml` — base config-only test
+        - `validate-<variant>.<platform>.yaml` — config-only variant
+
+        Use this for things like deprecated-syntax migration tests, schema edge cases, or platform-specific validation branches where building firmware adds no signal. A component may have any mix of `test.*.yaml` and `validate.*.yaml` files. Validate files never participate in bus-grouping; each one runs as its own `esphome config` invocation.
+
+        When a PR's only edits to a component are `validate.*.yaml` files (no source changes, no `test.*.yaml` changes, and the component isn't pulled in as a dependency of another changed component), CI skips the compile stage for that component entirely and only runs config validation. This is decided in `script/determine-jobs.py` via `_component_change_is_validate_only` and surfaced as the `validate_only_components` output that the `test-build-components-split` job consumes.
+
+    *   **Test Grouping with Packages:** Components that use shared bus packages can be grouped together in CI to reduce build count. **Never define buses (uart, i2c, spi, modbus) directly in test YAML files** — always use packages from `test_build_components/common/`.
+
+        All includes in test files must go through dict-style `packages:` so that batch grouping works correctly — the grouping scripts only understand dict-style packages. Never use list-style packages (`packages: [- !include ...]`) or top-level merge keys (`<<: !include common.yaml`). Bus packages are keyed by the bus name; the component's `common.yaml` is keyed by the component name (e.g. `cst328: !include common.yaml`):
+        ```yaml
+        # test.esp32-idf.yaml — everything included via named packages
+        packages:
+          uart: !include ../../test_build_components/common/uart_115200/esp32-idf.yaml
+          my_component: !include common.yaml
+        ```
+        ```yaml
+        # common.yaml — component config only, NO bus definitions
+        my_component:
+          id: my_instance
+
+        sensor:
+          - platform: my_component
+            name: My Sensor
+        ```
+        Components that define buses directly are flagged as "NEEDS MIGRATION" and cannot be grouped, increasing CI build time.
+        `!extend` and `!remove` in a `test.*.yaml` also make the component ungroupable; add a standalone entity with its own id instead.
+
+    *   **Testing All Components Together:** To verify that all components can be tested together without ID conflicts or configuration issues, use:
+        ```bash
+        ./script/test_component_grouping.py -e config --all
+        ```
+        This tests all components in a single build to catch conflicts that might not appear when testing components individually. Use `-e config` for fast configuration validation, or `-e compile` for full compilation testing.

+        ESP devices run for months with small heaps shared between Wi-Fi, BLE, LWIP, and application code. Over time, repeated allocations of different sizes fragment the heap.

+
+        **Heap allocation after `setup()` should be avoided unless absolutely unavoidable.** Every allocation/deallocation cycle contributes to fragmentation. ESPHome treats runtime heap allocation as a long-term reliability bug, not a performance issue. Helpers that hide allocation (`std::string`, `std::to_string`, string-returning helpers) are being deprecated and replaced with buffer and view based APIs.
+
+        **STL Container Guidelines:**
+
+        ESPHome runs on embedded systems with limited resources. Choose containers carefully:
+
+        1. **Compile-time-known sizes:** Use `std::array` instead of `std::vector` when size is known at compile time.
+           ```cpp
+           // Bad - generates STL realloc code
+           std::vector<int> values;
+
+           // Good - no dynamic allocation
+           std::array<int, MAX_VALUES> values;
+           ```
+           Use `cg.add_define("MAX_VALUES", count)` to set the size from Python configuration.
+
+           **For byte buffers:** Avoid `std::vector<uint8_t>` unless the buffer needs to grow. Use `std::unique_ptr<uint8_t[]>` instead.
+
+           > **Note:** `std::unique_ptr<uint8_t[]>` does **not** provide bounds checking or iterator support like `std::vector<uint8_t>`. Use it only when you do not need these features and want minimal overhead.
+
+           ```cpp
+           // Bad - STL overhead for simple byte buffer
+           std::vector<uint8_t> buffer;
+           buffer.resize(256);
+
+           // Good - minimal overhead, single allocation
+           std::unique_ptr<uint8_t[]> buffer = std::make_unique<uint8_t[]>(256);
+           // Or if size is constant:
+           std::array<uint8_t, 256> buffer;
+           ```
+
+        2. **Compile-time-known fixed sizes with vector-like API:** Use `StaticVector` from `esphome/core/helpers.h` for compile-time fixed size with `push_back()` interface (no dynamic allocation).
+           ```cpp
+           // Bad - generates STL realloc code (_M_realloc_insert)
+           std::vector<ServiceRecord> services;
+           services.reserve(5);  // Still includes reallocation machinery
+
+           // Good - compile-time fixed size, no dynamic allocation
+           StaticVector<ServiceRecord, MAX_SERVICES> services;
+           services.push_back(record1);
+           ```
+           Use `cg.add_define("MAX_SERVICES", count)` to set the size from Python configuration.
+           Like `std::array` but with vector-like API (`push_back()`, `size()`) and no STL reallocation code.
+
+           **Listener and child-entity registration lists are the most common case, and the most commonly
+           missed.** A `register_*()` method called once per child at code generation time has a count that
+           is known at compile time, so it should never be a `std::vector`. Use `cg.slot_counter()`: it
+           returns a function that each consumer calls once per slot it will occupy, and after every
+           `to_code` has run it emits the define with the final count. When nothing registers, no define is
+           emitted and the storage plus its registration method compile out entirely.
+           ```python
+           # hub component's __init__.py
+           _request_listener_slot = cg.slot_counter("MY_COMPONENT_LISTENER_COUNT")
+
+
+           async def register_listener(hub: MockObj, var: MockObj) -> None:
+               _request_listener_slot()
+               cg.add(hub.register_listener(var))
+           ```
+           When several instances each own a list declared at the same size (one per hub of a
+           `MULTI_CONF` component), pass the owning object as the key, `_request_listener_slot(str(hub))`;
+           the define is then the largest count any one key requested instead of the total.
+           ```cpp
+           #ifdef MY_COMPONENT_LISTENER_COUNT
+             void register_listener(MyComponentListener *listener);
+           #endif
+            protected:
+           #ifdef MY_COMPONENT_LISTENER_COUNT
+             StaticVector<MyComponentListener *, MY_COMPONENT_LISTENER_COUNT> listeners_;
+           #endif
+           ```
+           Request slots from `to_code`, not from a job that runs after `CoroPriority.FINAL` - a late
+           request raises rather than silently undercounting.
+
+        3. **Runtime-known sizes:** Use `FixedVector` from `esphome/core/helpers.h` when the size is only known at runtime initialization.
+           ```cpp
+           // Bad - generates STL realloc code (_M_realloc_insert)
+           std::vector<TxtRecord> txt_records;
+           txt_records.reserve(5);  // Still includes reallocation machinery
+
+           // Good - runtime size, single allocation, no reallocation machinery
+           FixedVector<TxtRecord> txt_records;
+           txt_records.init(record_count);  // Initialize with exact size at runtime
+           ```
+           **Benefits:**
+           - Eliminates `_M_realloc_insert`, `_M_default_append` template instantiations (saves 200-500 bytes per instance)
+           - Single allocation, no upper bound needed
+           - No reallocation overhead
+           - Compatible with protobuf code generation when using `[(fixed_vector) = true]` option
+
+        4. **Small datasets (1-16 elements):** Use `std::vector` or `std::array` with simple structs instead of `std::map`/`std::set`/`std::unordered_map`.
+           ```cpp
+           // Bad - 2KB+ overhead for red-black tree/hash table
+           std::map<std::string, int> small_lookup;
+           std::unordered_map<int, std::string> tiny_map;
+
+           // Good - simple struct with linear search (std::vector is fine)
+           struct LookupEntry {
+             const char *key;
+             int value;
+           };
+           std::vector<LookupEntry> small_lookup = {
+             {"key1", 10},
+             {"key2", 20},
+             {"key3", 30},
+           };
+           // Or std::array if size is compile-time constant:
+           // std::array<LookupEntry, 3> small_lookup = {{ ... }};
+           ```
+           Linear search on small datasets (1-16 elements) is often faster than hashing/tree overhead, but this depends on lookup frequency and access patterns. For frequent lookups in hot code paths, the O(1) vs O(n) complexity difference may still matter even for small datasets. `std::vector` with simple structs is usually fine—it's the heavy containers (`map`, `set`, `unordered_map`) that should be avoided for small datasets unless profiling shows otherwise.
+
+        5. **Strings set once from configuration:** Use `StringRef` (`esphome/core/string_ref.h`) rather than
+           `std::string`. Code generation passes a string literal that lives in flash for the life of the
+           program, so storing a `std::string` copies it onto the heap for nothing. `StringRef` is a
+           non-owning pointer plus length; it does not copy, and it must only ever refer to storage that
+           outlives it (a string literal, or a buffer owned elsewhere).
+           ```cpp
+           // Bad - heap copy of a literal that is already in flash
+           void set_keys(std::string keys) { this->keys_ = std::move(keys); }
+           std::string keys_;
+           ```
+           ```cpp
+           // Good - no allocation
+           void set_keys(const char *keys) { this->keys_ = StringRef(keys); }
+           StringRef keys_;
+           ```
+
+        6. **Avoid `std::deque`:** It allocates in 512-byte blocks regardless of element size, guaranteeing at least 512 bytes of RAM usage immediately. This is a major source of crashes on memory-constrained devices.
+
+        7. **Never use `new (std::nothrow)`:** On ESP-IDF exceptions are disabled, so a failed nothrow allocation aborts instead of returning `nullptr`. Use `RAMAllocator` from `esphome/core/helpers.h`; CI rejects `std::nothrow`.
+
+        8. **Detection:** Look for these patterns in compiler output:
+           - Large code sections with STL symbols (vector, map, set)
+           - `alloc`, `realloc`, `dealloc` in symbol names
+           - `_M_realloc_insert`, `_M_default_append` (vector reallocation)
+           - Red-black tree code (`rb_tree`, `_Rb_tree`)
+           - Hash table infrastructure (`unordered_map`, `hash`)
+
+        **Prioritize optimization effort for:**
+        - Core components (API, network, logger)
+        - Widely-used components (mdns, wifi, ble)
+        - Components causing flash size complaints
+
+        Note: Avoiding heap allocation after `setup()` is always required regardless of component type. The prioritization above is about the effort spent on container optimization (e.g., migrating from `std::vector` to `StaticVector`).
+
+        **Callback Managers:**
+
+        ESPHome provides two callback manager types in `esphome/core/helpers.h` for the observer pattern. Both support `std::function`, lambdas, and lightweight forwarder structs via their templatized `add()` method.
+
+        | Type | Idle overhead (32-bit) | When to use |
+        |------|----------------------|-------------|
+        | `CallbackManager<void(Ts...)>` | 12 bytes (empty `std::vector`) | Callbacks are always or almost always registered |
+        | `LazyCallbackManager<void(Ts...)>` | 4 bytes (`nullptr`) | Callbacks are often not registered (common case) |
+
+        `LazyCallbackManager` is a drop-in replacement for `CallbackManager` that defers allocation until the first callback is added. Prefer it for entity-level callbacks where most instances have no subscribers.
+
+        **Important:** Registration methods that add to a callback manager **must always be templatized** to accept both `std::function` and pointer-sized forwarder structs (used by `build_callback_automation`). Never use `std::function` in the method signature:
+        ```cpp
+        // Bad -- forces heap allocation for forwarder structs
+        void add_on_state_callback(std::function<void(bool)> &&callback) {
+          this->state_callback_.add(std::move(callback));
+        }
+
+        // Good -- accepts any callable without forcing std::function wrapping
+        template<typename F> void add_on_state_callback(F &&callback) {
+          this->state_callback_.add(std::forward<F>(callback));
+        }
+        ```
+
+    *   **State Management:** Use `CORE.data` for component state that needs to persist during configuration generation. Avoid module-level mutable globals.
+
+        **Bad Pattern (Module-Level Globals):**
+        ```python
+        # Don't do this - state persists between compilation runs
+        _component_state = []
+        _use_feature = None
+
+
+        def enable_feature():
+            global _use_feature
+            _use_feature = True
+        ```
+
+        **Bad Pattern (Flat Keys):**
+        ```python
+        # Don't do this - keys should be namespaced under component domain
+        MY_FEATURE_KEY = "my_component_feature"
+        CORE.data[MY_FEATURE_KEY] = True
+        ```
+
+        **Good Pattern (dataclass):**
+        ```python
+        from dataclasses import dataclass, field
+        from esphome.core import CORE
+
+        DOMAIN = "my_component"
+
+
+        @dataclass
+        class MyComponentData:
+            feature_enabled: bool = False
+            item_count: int = 0
+            items: list[str] = field(default_factory=list)
+
+
+        def _get_data() -> MyComponentData:
+            if DOMAIN not in CORE.data:
+                CORE.data[DOMAIN] = MyComponentData()
+            return CORE.data[DOMAIN]
+
+
+        def request_feature() -> None:
+            _get_data().feature_enabled = True
+
+
+        def add_item(item: str) -> None:
+            _get_data().items.append(item)
+        ```
+
+        If you need a real-world example, search for components that use `@dataclass` with `CORE.data` in the codebase. Note: Some components may use `TypedDict` for dictionary-based storage; both patterns are acceptable depending on your needs.
+
+        **Why this matters:**
+        - Module-level globals persist between compilation runs if the host process (e.g. device-builder) doesn't fork/exec
+        - `CORE.data` automatically clears between runs
+        - Namespacing under `DOMAIN` prevents key collisions between components
+        - `@dataclass` provides type safety and cleaner attribute access
 
 *   **Security:** Be mindful of security when making changes to the API, web server, or any other network-related code. Do not hardcode secrets or keys.

-*   Only features documented at [esphome.io](https://esphome.io) are public API for components; all `public`
-    members of `esphome/core/` and base classes are public API. Aim for a 6-month deprecation window
-    (`ESPDEPRECATED` in C++, `cv.rename_key(..., removed_in=...)` for config keys) and document the migration
-    path in the PR description. The `breaking-changes` skill has the full policy, checklist and patterns.
+*   **Public C++ API:**
+    *   **Components**: Only documented features at [esphome.io](https://esphome.io) are public API. Undocumented `public` members are internal.
+    *   **Core/Base Classes** (`esphome/core/`, `Component`, `Sensor`, etc.): All `public` members are public API.
+    *   **Components with Global Accessors** (`global_api_server`, etc.): All `public` members are public API (except config setters).
 
+*   **Public Python API:**
+    *   All documented configuration options at [esphome.io](https://esphome.io) are public API.
+    *   Python code in `esphome/core/` actively used by existing core components is considered stable API.
+    *   Other Python code is internal unless explicitly documented for external component use.
+
+*   **Breaking Changes Policy:**
+    *   Aim for **6-month deprecation window** when possible
+    *   Clean breaks allowed for: signature changes, deep refactorings, resource constraints
+    *   Must document migration path in PR description (generates release notes)
+    *   Blog post required for core/base class changes or significant architectural changes
+    *   Full details: https://developers.esphome.io/contributing/code/#public-api-and-breaking-changes
+
+*   **Breaking Change Checklist:**
+    - [ ] Clear justification (RAM/flash savings, architectural improvement)
+    - [ ] Explored non-breaking alternatives
+    - [ ] Added deprecation warnings if possible (use `ESPDEPRECATED` macro for C++)
+    - [ ] Documented migration path in PR description with before/after examples
+    - [ ] Updated all internal usage and esphome.io
+    - [ ] Tested backward compatibility during deprecation period
+
+*   **Deprecation Pattern (C++):**
+    ```cpp
+    // Remove before 2026.6.0
+    ESPDEPRECATED("Use new_method() instead. Removed in 2026.6.0", "2025.12.0")
+    void old_method() { this->new_method(); }
+    ```
+
+*   **Deprecation Pattern (Python):**
+    For a renamed config key, use the shared `cv.rename_key` validator with `removed_in` (and `component` for context) — it warns and auto-migrates:
+    ```python
+    CONFIG_SCHEMA = cv.All(
+        cv.rename_key(
+            CONF_OLD_KEY, CONF_NEW_KEY, removed_in="2026.6.0", component="my_component"
+        ),
+        cv.Schema({...}),
+    )
+    ```
+    For other deprecations, warn manually during validation:
+    ```python
+    # Remove before 2026.6.0
+    if CONF_OLD_KEY in config:
+        _LOGGER.warning(
+            f"'{CONF_OLD_KEY}' deprecated, use '{CONF_NEW_KEY}'. Removed in 2026.6.0"
+        )
+        config[CONF_NEW_KEY] = config.pop(CONF_OLD_KEY)  # Auto-migrate
+    ```
