How do I find a open door sensor that will work with Google? This has
been un-believably hard to find. All I want is a routine that when this
door opens, it will turn on a light that is on a smart switch.
I also have the same question. I have spent quite a bit of money on
Google / Nest cameras and thermostats and I can't find a simple sensor
that will tell me when a door is open!
