I’m looking for a sensor (some kind of optical barrier) which detects if someone walks through a door.
I’d like to switch on and off the lights in the less frequently used rooms based on this sensor. I have installed motion sensors, currently, but after leaving the room the light stays switched on for a couple of minutes. I find that suboptimal.
Therefore, I’m looking for something like this sensor from Homematic IP: https://www.homematic-ip.com/en/products/detail/homematic-ip-passage-sensor-with-direction-recognition.html
I’d buy this sensor but as far as I understood it, it sends the data via radio and all of my components use zigbee.
Do you know (and can recommend) a sensor similar to this one which uses zigbee?
