Thermostat Application Override APIs#

To override any of the following hooks, declare the corresponding *Impl() method in CustomerAppTask.h and implement it in CustomerAppTask.cpp. Ensure that the method signature matches the declaration in autogen/AppTaskImpl.h.

AppTask#


Override	Public API	Default behavior
`AppInitImpl`	`AppInit`	Registers the button callback, sets the LCD UI, and initializes the thermostat.
`InitThermostatImpl`	`InitThermostat`	Initializes the sensor, UI, and periodic temperature sampling.
`InitSensorImpl`	`InitSensor`	Initializes the hardware temperature sensor if it is present.
`GetTemperatureImpl`	`GetTemperature`	Reads the Si70xx sensor if it is present; otherwise, provides a simulated temperature.
`ButtonEventHandlerImpl`	`ButtonEventHandler`	Routes function-button events to the base application handler.
`SensorTimerEventHandlerImpl`	`SensorTimerEventHandler`	Posts an application event to update the temperature when the sensor timer expires.
`TemperatureUpdateEventHandlerImpl`	`TemperatureUpdateEventHandler`	Samples the temperature and updates the Thermostat `LocalTemperature` attribute.
`DMPostAttributeChangeCallbackImpl`	`DMPostAttributeChangeCallback`	Handles attribute changes from the Thermostat cluster and monitors attribute changes from the Identify cluster.
`DMThermostatClusterInitImpl`	`DMThermostatClusterInit`	Installs the default Thermostat delegate on an endpoint.
