Here are five reasons why the Aqara Door and Window sensor is the best. First, it is smaller than most other sensors I tested. Second, the battery life was twice as long as the next best sensor. Third, it was the most accurate at measuring over 800,000 open/close cycles. Fourth, Aqara sensors use a Zigbee protocol, which makes them compatible with numerous other systems such as Home Assistant or SmartThings. Lastly, it was one of the cheapest sensors tested.
