Protect your home from water damage with the SONOFF smart kit — a reliable Zigbee water leak detector and an extension cable for monitoring even in hard-to-reach places. It offers detection from 0.5 mm, IP67 durability, gold-plated probes, up to 5-year battery life, and instant alerts in the eWeLink app with support for Alexa, Google Home, and SmartThings.
Precise detection and high durability
The sensor detects water from as little as 0.5 mm, and thanks to its IP67 rating and gold-plated probes it resists corrosion and harsh conditions. The CR2477 battery lasts up to 5 years without frequent replacement.
Expanded coverage with the WLDC200 cable
The 2 m extension cable covers larger areas, can be daisy-chained, and secured using the included clips. The durable PC/ABS design works from -10 to 60 °C.
Smart alerts and broad compatibility
Instant push notifications in eWeLink, audible alarms via the Zigbee gateway, and email (eWeLink Advanced). Works with Alexa, Google Home, SmartThings, IFTTT, and Home Assistant (ZHA/Zigbee2MQTT). Requires a compatible Zigbee gateway.
The kit combines the precise SONOFF water leak sensor with Zigbee 3.0 and an extension cable that extends coverage to challenging areas. Thanks to its concave design and gold-plated probes, the sensor reliably detects even a minimum water level of 0.5 mm. The IP67 rating ensures flawless operation in demanding environments, while the CR2477 battery provides up to 5 years of life.
The 2 m extension cable enables flexible installation around washers, dishwashers, water heaters, in basements, and beneath HVAC units. The cable can be daisy-chained to cover larger areas and can be neatly secured with the included mounting clips. The system sends push alerts in the eWeLink app, audible alarms via the Zigbee gateway, and (for eWeLink Advanced) email notifications.
