Detection range of up to 16.4 ft (5m) with 90° horizontal and 55° vertical field of view. The magnet and sensor need to be within 1.2 inches (30mm) of each other for reliable operation. Powered by AAA batteries lasting up to 3 years, it works locally with SwitchBot devices or connects to Alexa/Google via SwitchBot Hub.
