SONOFF SNZB-05P Zigbee Water Leak Sensor with Detection Cable

Protect your home from costly water damage with the SONOFF SNZB-05P Zigbee Water Leak Sensor – a powerful, smart leak detector equipped with multi-mode detection, long battery life, and IP67 waterproof protection. Whether you're guarding your bathroom, kitchen, basement, laundry room, or under-sink area, this sensor is the perfect solution.

Designed using Zigbee 3.0 protocol, it delivers real-time leak detection and instant alerts via the eWeLink App, even when your WiFi goes down—thanks to Zigbee local scene triggers. It supports voice assistant integration, including Alexa and Google Home, plus email and SMS alerts through the eWeLink advanced plan.

With a 5-year battery life powered by CR2477 and a 130m open-space range, the SNZB-05P ensures long-term, reliable coverage. Its elevated probe design detects as little as 0.5mm of water, while the concave water collection zone is ideal for detecting slow drips. You can also connect it with an extension cable (included in kit versions) for wide-area monitoring, and even series-connect multiple cables without length limitations.

Crafted with UV-resistant PC+ABS material and gold-plated probes, it offers long-lasting performance and resistance to corrosion. The IP67 waterproof rating ensures durability—even in harsh or humid environments.

Whether you want to monitor a narrow pipe or a large surface, the SNZB-05P adapts to your setup. When leaks occur, it alerts your smartphone every 10 minutes until resolved—so nothing goes unnoticed.
