Multi Sensor 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, initializes the occupancy LED and display, and starts the sensor manager.
`InitSensorManagerImpl`	`InitSensorManager`	Initializes the sensor clusters, registers the attribute listener, and schedules periodic sampling.
`GetTemperatureAndHumidityImpl`	`GetTemperatureAndHumidity`	Reads the Si70xx sensor if it is present; otherwise, provides simulated temperature and humidity values.
`ButtonEventHandlerImpl`	`ButtonEventHandler`	Routes events from the function and occupancy-toggle buttons.
`ProcessButtonEventImpl`	`ProcessButtonEvent`	Toggles the Occupancy attribute for an application button event.
`TriggerSensorActionImpl`	`TriggerSensorAction`	Samples temperature and humidity and updates their measured value attributes.
`OccupancyAttributeUpdateEventImpl`	`OccupancyAttributeUpdateEvent`	Updates the occupancy LED and display after the Occupancy attribute changes.
`SensorAttributeUpdateEventImpl`	`SensorAttributeUpdateEvent`	Updates the display after a temperature or humidity change.
`OnAttributeChangedImpl`	`OnAttributeChanged`	Converts Occupancy, Temperature Measurement, and Relative Humidity Measurement changes into application events.
`DMPostAttributeChangeCallbackImpl`	`DMPostAttributeChangeCallback`	Logs Identify attribute changes.
