Overview

Protect your home from costly water damage with the SONOFF SNZB-05P Zigbee 3.0 water leak sensor. This compact smart detector continuously watches for leaks and drips, then pushes real-time alerts straight to your phone the moment water is detected, so you can act fast before damage and mold set in.

Built for versatile placement, the elevated probe design senses even a shallow 0.5 mm liquid level and works reliably on metal surfaces without false triggers. A concave water collection area catches drips to stop leaks at the source, making it ideal for basements, laundry rooms, under sinks, and around water heaters.

Running on a long-life CR2477 battery with over 5 years of use, it pairs seamlessly with Zigbee 3.0 gateways and integrates with Home Assistant, Google, and Alexa ecosystems for a truly connected smart home safety setup.
