+        rebuilds the callback and re-queues a scheduler item, and the period drifts.
+    *   **Scheduler ids:** name a timer only when it must be cancelled or replaced, and use a
+        `static constexpr uint32_t` id, never a string. Ids are per component instance and cannot clash with other
+        components, so number them from 0 and keep all of a component's ids together in one place.

+    *   **Constant data lives in RAM on ESP8266** unless marked `PROGMEM`: `const` tables, class-scope
+        constant arrays, and in-class `std::array` initializers (a `.rodata` template plus a copy). Mark the
+        table `PROGMEM` and read it with `progmem_memcpy()` or `progmem_read_byte()` (`esphome/core/hal.h`);
+        for a table of structs copy the whole entry out and return the copy, never a pointer into flash.
+        On other platforms they are a plain `memcpy` and dereference, so no `#ifdef` is needed. Declare log tags with
+        `ESPHOME_LOG_TAG(TAG, "name")`, pass status text as `LOG_STR`, e.g.
+        `this->mark_failed(LOG_STR(ESP_LOG_MSG_COMM_FAIL))`, and give an action whose payload is a byte array
+        a `TEMPLATABLE_BYTES` field so a static code stays in flash.
+    *   **Fixed sets of names** (status words, model names): a `PROGMEM_STRING_TABLE` (`esphome/core/progmem.h`),
+        logged with `get_log_str` and `LOG_STR_ARG`, copied out with `ESPHOME_strncpy_P` before `publish_state`.
+        A `dump_config` helper that picks a name returns `const LogString *` from `LOG_STR(...)`.
+    *   **CRCs and bit tricks** come from `esphome/core/helpers.h` (`crc8`, `crc16`, `reverse_bits`, `encode_uint16`);
+        pick the helper's polynomial and bit-order arguments instead of writing a CRC loop.
+    *   **An unset float is `NAN`**, not `optional<float>`; the optional costs 4 to 8 bytes of padding per member.
+    *   **`PollingComponent` first runs `update()`** after a random share of the interval; call `this->update()` at the
+        end of `setup()` when the entities need a state at boot.
+    *   **A multi-step command sequence** leaves the step pending when the answer is malformed, so the existing
+        resend and give-up logic handles it; never advance on an answer that was only logged.
+    *   **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).
+    *   **A global feature define** says the code is compiled in, not that this instance uses it: keep the
+        per-instance check (`if (this->aux_device_ == ...)`) inside the `#ifdef`.
+    *   **Failures after `setup()`:** `mark_failed()` is for `setup()` only. A runtime read or write failure
+        sets `status_set_warning()` and the next success clears it; writes skip work when `is_failed()`.
+    *   **Fixed platform facts compile to nothing:** gate on `#ifdef USE_ESP8266` and friends, not on a
+        runtime check of something the build already knows.
    *   **Logging string literals:** wrap literals passed as `%s` arguments in `LOG_STR_LITERAL()` so they
        can be stored in flash rather than RAM.
