    easy
    This sensor is added very easy with smart life, and brings all the product pulas and rubber paste. It has very good quality, especially having something interesting, if a trap is removed also alerts you. Use 3 AAA batteries so it is better because you can use the rechargeable. In the states shown App, open, closed, open and semi battery condition What parent is that you can set scenes with smart life to automate and automatically! loa adds ALEXA so the sensor is also within the app ALEXA. Everything in life smar cloud, this is a better option than wyze as it is very limited. Bad or unfavorable would be the size of the master, it is very large (size AAA batteries) so you should consider that

    Easy to setup
    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.

    Works well with app
    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.
