           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`.

           `spi.new_spi_component`, `modbus.new_modbus_client_component`, `ble_client.new_ble_node_component`)

+/**
+ * Sends the states of local sensors and binary sensors over a packet interface, and publishes the states received
+ * from other devices to remote entities.
+ *
+ * Each device numbers its sensors and its binary sensors from 0, and sends a dictionary that gives the id for each
+ * number. Data packets then refer to an entity by its number. Every packet carries the sender's dictionary id, a hash
+ * of its device name and dictionary, so that a receiver knows which device sent it and which dictionary applies.
+ * All values are little endian.
+ *
+ * Dictionary packet:
+ * - type: 1 byte, PACKET_DICTIONARY;
+ * - dictionary id: 4 bytes;
+ * - part: 1 byte, the packet's index in the dictionary in bits 0-6, counting from 0 and wrapping, and bit 7 set on
+ *   the last packet;
+ * - sender's device name: length (1 byte), then the name;
+ * - one or more sections, each: entity type (1 byte), first number (1 byte), count (1 byte), then for each entity
+ *   its id: length (1 byte), then the id.
+ *
+ * Data packet:
+ * - type: 1 byte, PACKET_DATA;
+ * - dictionary id: 4 bytes;
+ * - records, to the end, each a 16-bit tag, then its payload. The tag holds the entity's number in bits 0-7, its type
+ *   in bits 8-12, and the payload form in bits 13-14: none, with the state in bit 15 (binary sensors); 4 bytes (a
+ *   sensor's float); a length byte, then that many bytes; or no state, with no payload. The form gives the record's
+ *   size, so a receiver skips records of types it does not know.
+ *
+ * Every packet is checked in full before anything in it is used, so a damaged or forged packet changes no state.
+ *
+ * Dictionary request packet, sent by a device that receives data with a dictionary id it has not received in full,
+ * with every part in order:
+ * - type: 1 byte, PACKET_REQUEST;
+ * - the dictionary id wanted: 4 bytes.
+ *
+ * Changed states are sent from loop(). The dictionary and all states are sent at boot, when a session layer reports
+ * the peer connected, when the dictionary is requested, and every update interval. Unless the interface has both a
+ * session and a reliability layer, the update interval defaults to DEFAULT_UPDATE_INTERVAL_MS. When the interface
+ * refuses a packet, sending is tried again after a delay, and a warning is set once it has refused every packet for a
+ * minute. With a remote timeout, a remote entity loses its state when
+ * none arrives for it within the timeout.
