@Opaquer

know whether the light is on/off.

I wonder whether there is some kind of reed switch hack suitable for this.

A list of door sensor / reed sensor hacks! (Aqara, Xiaomi, others)

There’s so many cool little door sensor hacks floating around that I thought it might be useful to have a meta thread? Like this one.. I really like the Aqara ones, which are small, cheap, and reliable in my experience. I’ll add the one’s I know about, and add one I’m just playing with.

Something you could maybe even mount inside the led cover? Like a photoresitor attached to a door sensor.

Not sure if the bright resistance would be low enough?

Edit: Someone has suggested the cut-off for Aqara sensors is about 2k ohm so linked ones are unlikely to work.

A photoresistor will probably work with the Aqara sensor so long as the resistance dips below 2K ohms (seems to me like that’s the spot). Trick is simply to find what threshold resistance the sensor accepts. If the photoresistor is (when not lit) infinite resistance (or some very high value) then it might work. Not sure about battery consumption if the photoresistor has a non-infinite resistance when not lit.
