It offers up to 2 years of battery life powered by 2 AAA batteries, supports Alexa routines for customized smart home automation, and provides real-time monitoring through the Third Reality app. Designed for indoor use, it ensures reliable contact even on doors/windows with frame height differences, making it a versatile and essential addition to any connected home security system. ## Description Door and window sensor can directly work with compatible ECHO. And its compact design can fit in most doors and windows. Most of the doors or windows have a height difference from the doors' or windows' frame. With the special design the height difference can be reduced to make sure the two parts of the door sensor have a stable contact. Simply peel off the protective layer of double-sided tape and stick the two parts of the door sensor to the door and the door frame. You can monitor every door and windows in your home and create routines to send messages to your smartphone when the door or window is open. You also can create routines that are triggered by the on/off status of the door sensor. Review: very good - working fine Review: It's flawless I love it - Yes, this is great!
