Sonoff SNZB-05P is a Zigbee 3.0 water leak sensor designed to detect moisture and flooding.

## Long description

SONOFF SNZB-05P ZigBee flood/water leak sensor kit with WLDC200 cable provides reliable detection of water leaks and flooding. The SNZB-05P sensor uses ZigBee 3.0 communication and features gold-plated probes and IP67 protection for corrosion resistance and operation in wet environments. The included WLDC200 2 m extension cable expands sensing reach to hard-to-reach locations such as basements, under HVAC equipment or around water heaters, enabling timely detection of small leaks.
Advantages
The kit combines a high-precision SNZB-05P sensor with a WLDC200 extension cable to deliver extended monitoring range and flexible installation. The sensor detects water levels from 0.5 mm, offers up to five years of battery life on the included CR2477 battery, and supports long-range ZigBee communication. IP67 housing and gold-plated probes increase reliability in damp or corrosive conditions. Integration with popular smart home platforms and eWeLink notifications ensures remote alerts and centralized control.

Place the probe contacts where leaks are most likely to appear; use the supplied clamps to secure the cable. Configure notifications in the app to receive push alerts, audio alarms via a ZigBee gateway and optional email alerts (requires eWeLink Advanced subscription). Regularly check battery status in the app and replace the CR2477 battery when indicated.
Recommendations
The kit is suitable for homes and industrial sites where early leak detection is required; for larger areas, connect WLDC200 cables in series as needed and keep probes clear of heavy debris. Maintain periodic inspections of cable routing and probe contacts to ensure reliable operation.
