Sonoff Water Leak Sensor (Zigbee)

This sensor features a concave water collection design that quickly identifies drips and leaks at their source. It’s ideal for placement near washing machines, geysers, sinks, or water tanks. The elevated probe ensures accurate detection without false triggers on metal or damp surfaces.

The SNZB-05P connects to Sonoff Zigbee hubs like the Zigbee Bridge Pro, NSPanel Pro, or iHost, and is also compatible with SmartThings and Alexa Zigbee. It supports local scene execution, allowing it to trigger alarms or shut off valves even if the internet is down.

Users can extend its detection range using optional water leak detection cables, which can be connected in series without length limits. The sensor is powered by a CR2477 coin cell battery, offering long-lasting performance.
