The Sonoff SNZB-05P is a compact Zigbee 3.0 water leak sensor designed to protect your home from accidental flooding and drips. It features a specialized concave water collection design with elevated probes that allow it to detect liquid levels as low as 0.5 mm, ensuring you are alerted to leaks almost immediately. To withstand damp environments, the device is built from ABS/PC materials with an IP67 waterproof rating, making it durable enough for placement near washing machines, sinks, or water heaters. Operating on a CR2477 battery, this sensor can last up to 5 years, while the eWeLink app provides helpful low battery indicators so you are never caught off guard. The small 48 x 48 x 21.6 mm frame weighs only 45 g, allowing it to fit discreetly in tight spaces. Because it requires a compatible Zigbee hub, such as the Sonoff Zigbee Bridge, you can integrate it with Alexa or Google Assistant to receive vocal notifications or set up scene linkages that trigger other smart devices when water is detected. It remains functional in temperatures ranging from -10 to +60 °C, providing reliable monitoring across various household conditions.
