I like these things. Easy to setup, reliable sensor for doors and windows. We have these for three doors and they work great. We set them up in not even five minutes, used the tape to attach each piece of the sensor to the door and frame, and it was recognized by the app. We mounted ours in the upper areas of the door, one piece on the door, one on the frame itself. We found that the two components do not have to be touching directly in order for these to work, I have recently come home from work to find my door was left unlocked. Now with the automation I have setup, the door locks as soon as this sensor reports closed (nearly instantaneous)! They are great for our uses.

The install process was quick and easy, only taking a few minutes. I screwed in the bulb, turned on the lamp and followed the simple instructions through the app. So far, the actions have worked flawlessly. I also like the option to set up schedules manually. I like being able to use app to control the bulbs. I will definitely be purchasing more to add to my ecosystem. Highly recommended.

We love it. After opening the box I had it setup and working in less than an hour. It was easy setting up this type of action via app and they work great. I can't tell you how much money I have wasted in the past. Worked perfecting for my house Really appricitate how simple it is to set it up with the app and then get it quickly added. Very pleased.
