Sonoff Water Leak Sensor (Zigbee)

Description

Sonoff Water Leak Sensor (Zigbee)

Protect your property from costly damage with the Sonoff Water Leak Sensor, a precision Zigbee leak detector that alerts you at the first sign of water. Designed with a raised probe that detects water as shallow as 0.5mm, this sensor ensures accurate, timely alerts without false triggers — even on metal surfaces. Its concave water collection design allows it to catch small drips early, helping you act fast to prevent flooding or pipe failures.

For wider coverage, connect an optional Sonoff Water Leak Detection Cable (sold separately), which can be daisy-chained with unlimited length to suit both tight and expansive areas. The Sonoff Water Leak Sensor integrates with Zigbee scenes for smart automation and can still sound local alarms via compatible gateways even if Wi-Fi is offline. It works with Sonoff NSPanel Pro, Sonoff iHost, and Home Assistant via ZHA or Zigbee2MQTT.
