SONOFF SNZB-05P - Water leak sensor, White

The SONOFF SNZB-05P Zigbee Water Leak and Flood Sensor Set with WLDC200 Cable is an indoor sensor for detecting water leaks and rising water. It uses Zigbee 3.0 and comes with a detection cable for monitoring narrow or concealed spaces. Raised probes and a concave collection area allow it to detect liquid levels as low as 0.5 mm. The cable can be positioned under sinks or around appliances where the sensor body may not fit. With a compatible Zigbee gateway, it can trigger local alarms and send notifications through the eWeLink app on iOS or Android. Typical locations include bathrooms, laundry rooms, basements, and areas near water heaters or sump pumps.

The housing is made from PC+ABS and has an IP67 rating. Power comes from one replaceable CR2477 battery, with a stated battery life of up to five years. The product is for indoor use and connects to a Zigbee gateway rather than directly to Wi-Fi. Supported smart-home integrations include Amazon Alexa, Google Assistant and SmartThings, as well as Home Assistant via ZHA or Zigbee2MQTT. Apple Home support requires a Matter Bridge.

• Maximum stated indoor transmission distance of 130 m — actual reach depends on the Zigbee network and installation environment.
• Adhesive mounting for installation on indoor surfaces.
• Battery-low status indication with a warning when the battery needs attention.
• Reset button for physical control of the sensor.
• 48 × 48 × 21.6 mm body, weighing 45 g — a compact form for placement in confined indoor areas.
