Detailed Description

Mixin holding the hub/device binding shared by the auto-generated per-device companion diagnostic sensors (device name, active issue, RSSI, last contact, exchange failures).

Companions differ from the main entity platforms (DeviceBoundEntity above) in that they only observe a device the main entity already registered: they never call add_device() or configure polling, they just subscribe to update notifications and republish their one value. This mixin centralizes that subscribe-and-republish ritual; each sensor class keeps only its value rendering (including its decision whether a given device state is publishable at all).

Member Function Documentation

register_companion_binding_()

void esphome::home_io_control::DeviceBoundCompanion::register_companion_binding_ ( const std::function< void(const IoDevice &)> & publish )

inlineprotected

Shared setup() body: subscribe to this device's updates and publish the initial state.

No-op when no parent is wired (codegen always wires one before setup() runs).

Parameters

publish

Renders and publishes the sensor's value from a device record — or skips publishing when the record has no meaningful value yet. Runs once immediately when the device is already registered, then again on every update notification for this device.

Definition at line 131 of file platform_entity_base.h.

set_device_id()

void esphome::home_io_control::DeviceBoundCompanion::set_device_id ( const std::string & id )

inline

Set the device ID whose state this companion sensor exposes.

Parameters

id	Hexadecimal node ID string (for example "123ABC").

Definition at line 122 of file platform_entity_base.h.

set_parent()

void esphome::home_io_control::DeviceBoundCompanion::set_parent ( IOHomeControlComponent * parent )

inline

Set the parent controller component.

Parameters

parent

Pointer to the IOHomeControlComponent instance.
