The Moen Smart Leak Detector is the better overall water leak sensor, winning on weather resistance, sensors, alerts and an on-device alert light. It joins 2.4 GHz Wi-Fi on its own. The Third Reality Water Leak Sensor answers with a lower price, a better owner rating, a 3-year battery and broader integrations (SmartThings and Home Assistant, plus a bridge for voice), but it is leak-only Zigbee with no LED. Choose the Moen Smart Leak Detector for hub-free freeze coverage; choose the Third Reality Water Leak Sensor for a cheap leak-only Zigbee node.
