Centralite 3-Series Water Sensor

$19.95

Buy on Amazon USA

The Centralite 3-Series Water Sensor wins this water leak sensor comparison on a 3-year battery plus temperature and freeze alerts the Aqara Water Leak Sensor T1 does not measure. The T1 is better reviewed, IP67 sealed, and reaches Google Home, Alexa, HomeKit, SmartThings, and Matter through an Aqara Hub, with Home Assistant natively. Both are Zigbee, both skip a local siren, and both are tiny discs. Choose the Centralite 3-Series Water Sensor for pipe-freeze automations; choose the Aqara Water Leak Sensor T1 for a sealed puck that can join almost every assistant through Aqara.
