YoLink Water Leak Sensor

The YoLink Water Leak Sensor uses LoRa technology to provide long-range leak detection—up to 1,000 feet to the YoLink Hub—for monitoring water heaters, washing machines, sump pumps, and other potential leak sources in locations where WiFi sensors wouldn't reach. The sensor sends immediate alerts when water is detected, enabling rapid response to prevent water damage.

The compact sensor lies flat on floors or mounts on walls with the probe extension cable for hard-to-reach locations. Battery life extends to 5+ years under normal conditions with low-battery alerts. The 100dB built-in siren provides local audible alert in addition to smartphone notifications.

Alexa and Google Assistant integration enables voice queries and routine triggers. The YoLink app provides alert configuration, sensor history, and automation rules. For monitoring leak-prone areas in basements, utility rooms, vacation homes, or commercial properties where range is challenging, YoLink's long-range protocol ensures reliable detection and notification regardless of distance from your router.
