I have quite a few of these around my house. One thing to note (could be good or bad depending on your situation) is that they come with a built in 4 minute motion delay. So when it no longer detects motion it waits 4 minutes before reporting the no motion status to Almond. If it detects motion during that 4 minutes, it resets its timer. For me this is exactly what I needed for some of the rules I wanted to set up.
One question though, mine all display temps in Celcius, anyone know how to change this to Fahrenheit?
