With the P2 sensor via Matter, I cannot select values above 1000 lux. And the description in some shops states that the sensor only measures up to 1500 lux.
That must be a error. Which version of the Aqara Home app are you using, and what type of smartphone do you have? iPhone? Android?
I can’t find it right now, but I can confirm that it exceeds 15,000 lux, as I have a light therapy lamp that reaches these values. When I hold the lamp in front of the P2 sensor, it stops at 1,500 lux, and the FP2 displays 15,000 lux. But I suspect it can go even higher.
I believe the sensor is not actually intended for the EU, but there are some people here in the forum who use it anyway.
