Great door and window sensor
Reviewed on 01/07/2017
I have a bunch of these on all my doors and windows connected to an Iris system. Well these only work with Iris but they do a good job and the batteries last over a year with normal use.
This is amazing!!

I expected this product to function as a window and door sensor, but I am amazed at how well it works as a freezer monitor. I was skeptical. A battery operated device, in a steel box, operating a 7 deg F. This sensor has been installed for a week, and it is working flawlessly.

I have both 1st and 2nd gen sensors and both work perfect. The rest of the 2nd gen product line is improved and pairing takes seconds with all my devices. All of my 1st gen devices work with my 2nd gen hub. Liking this more with each device I add.
