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.
1st and 2nd generation

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.
Great for the price!!!

I have been buying extra sensors for this price for the last weeks,always wanted to put an extra sensor in the other side of my windows since both sides can slide and open,even that the other side suppose to be secure,anyone can force and still open them,have a tilt sensor in my garage but wont activate unless the garage door is half way open,so installed a sensor there so even if the garage door is open for more than 2 inches it will notify me or trigger my alarm,got one in my fridge door,will let me know if the door has been left open for more than 5 minutes,will add one to the drawer were we keep our router,want to know if someone is messing with it,and want to try one in our vinyl fence gate, will try to seal the sensor with silicone so water or moisture won affect the sensor so will see if it works,for this price is worth trying!!
