2026 verdict
A five-year warranty on leak-and-freeze Wi-Fi: the X-Sense 2-in-1 Wi-Fi Water Leak & Freeze Detector is the better overall water leak sensor, winning on price, owner rating, warranty and alerts.
Both watch water and freeze risk over 2.4 GHz Wi-Fi. The Moen Smart Leak Detector still takes IP67 weather resistance, Alexa and an on-device alert light, plus a 48-inch sensing cable. Pick the X-Sense 2-in-1 Wi-Fi Water Leak & Freeze Detector for the longer warranty on leak-and-freeze Wi-Fi; pick the Moen Smart Leak Detector if you want Alexa, a tougher IP67 body and a remote probe.
