I am using the Aqara P1 Motion Sensor connected directly to Home Assistant via the Matter protocol.
The motion detection functionality is working correctly through Matter. However, I’ve noticed that the built-in light/illumination sensor data is not currently exposed or available within Home Assistant when using this Matter connection. I understand the hardware itself includes this sensor.
Could you please provide an update or any information on when support for the light sensor feature via Matter is planned or expected to be released for the P1 Motion Sensor? Is this functionality currently under development?
The light sensor of P1 passively reports illuminance values and depends on human interaction to initiate the reporting process. Unfortunately, this design limits its ability to provide real-time updates of illuminance values within the Matter protocol. I hope my answer will help you
