SONOFF Smart Zigbee Water Leak Sensor, IP67












SONOFF Smart Zigbee Water Leak Sensor, IP67

Detection from just 0.5 mm of water
The sensor’s concave body and raised probes detect even small drops. It immediately alerts you to leaks under the washing machine, in the kitchen, or in the basement to prevent major damage.

IP67 durability and gold‑plated probes
The IP67 dustproof and waterproof design is ideal for damp areas. Gold‑plated contacts have passed a 48‑hour salt spray test and provide outstanding corrosion resistance.

Smart alerts and local scenes
Push notifications in eWeLink, email reports (subscription), and an audible alarm via the hub. Thanks to local scenes, alerts work even during a Wi‑Fi outage.
Protect your home from costly damage. The SONOFF sensor detects a minimum water level of 0.5 mm thanks to its carefully designed concave structure and raised probe. The IP67 rating ensures flawless operation in basements, bathrooms, and kitchens, while corrosion‑resistant gold‑plated contacts ensure long service life.
With Zigbee 3.0, the connection is stable and fast, with local automations even without Wi‑Fi. The sensor works with Amazon Alexa, Google Home, and SmartThings, supports Home Assistant (ZHA/Zigbee2MQTT), and notifies you via eWeLink push, email (subscription), or the hub’s audible alarm. Redundant reporting every 10 minutes minimizes the chance of a missed event.
Ultra‑low‑power operation with a CR2477 battery provides up to 5 years of carefree use. The compact size and optional cabled probe make installation easy by the washer, dishwasher, water heater, and in hard‑to‑reach spots.
