  1. Paired easily with existing network, device shows state of circuit in UI

  2. Very big by modern standards

  3. Works perfectly in my HomeSeer setup.

  4. Works well but seems to run with motion sensor driver not contact sensor

  5. Haven’t been able to use this yet, so can’t review. Will do in due course…

  6. The first one I received had a dead battery, but once I had worked that out, I contacted Samotech and they sent another straight away, which worked perfectly. I use it with Home Assistant to do things like switch on garden lights when I open the door at night, warn me if I haven’t opened the door all evening on the day the bins go out, and so on.

  7. Excellent products & great value for money!

  8. Works very well even on my garage door that is 25m and 4 floors away.

  9. I’ve got six of these now on various doors and windows and use them in both Smartthings and Home Assistant. They work a treat and have never lost connection or given a false reading. Great little door/window sensors.
