Description
The SONOFF SNZB-05P is a Zigbee 3.0 water leak sensor that alerts you at the first sign of water. Its elevated probe design detects liquid levels as low as 0.5 mm and works reliably on metal surfaces without false triggers, while the concave water collection design quickly senses drips so you can stop leaks at the source.
When water is detected, it instantly pushes an app notification, and local Zigbee scenes can trigger gateway alarms even during Wi-Fi outages. Coverage can be extended with water leak detection cables (sold separately), which can be connected in series without length limitation to protect wide areas or narrow spots.
Note: a Zigbee gateway is required (see "Works With" below). This listing is for the sensor only; the detection cable is sold separately.
