Love it, love it, love it
I bought a couple of these sensors, the pro and the normal to test it. I had the pro to my garage door which is far from the hub. It works great! The price is awesome for the quality that we get. Besides, it was really easy to add it to the hub (SmartThings). Great job guys!
Excellent sensor
Easy to install, easy to use, it works very well.
