I just started to join this community and already have some question for which I didn’t find any solution on the internet. I have several old and new Samsung Android cell phones, which I would like to put on wall in rooms and use them as switch.
Is it possible to use or configure device build in proximity sensor (sensor which turn off screen during call) to report state out of call? I can see that this sensor works while I have call, but I don’t see status change out of call.
Do you have some idea how to use proximity sensor as switch?
