Updated September 2026

Data from Amazon and official Centralite and X-Sense sites.

Winner

X-Sense Wi-Fi Water Leak Detector

$15.99

Buy on Amazon USA

X-Sense also undercuts on price, carries an IP66 rating, and joins 2.4 GHz Wi-Fi plus Home Assistant with no Zigbee hub. Centralite still leads on temperature and freeze alerts and on SmartThings as a native Zigbee device. Neither has a status light. Choose the X-Sense Wi-Fi Water Leak Detector for a louder, longer-warrantied Wi-Fi puck; choose the Centralite 3-Series Water Sensor if freeze sensing on a Zigbee mesh matters more than a local horn.
