The Sonoff SNZB-05P is a Zigbee 3.0 water leak sensor designed to protect your home from accidental flooding. It features a highly sensitive detection system capable of spotting liquid levels as low as 0.5 mm, utilizing a concave water collection design for drips and an elevated probe specifically for metal surfaces to prevent false triggers. The device is housed in a white ABS casing with an IP67 rating, ensuring it remains durable and water-resistant in damp environments. To provide flexible installation, it comes with a 2-meter WLDC200 cable that supports unlimited series connections if you need to extend the reach. The sensor is powered by a CR2477 battery, which offers a long service life of over five years. It integrates seamlessly with hubs like the SONOFF iHost, NSPanel Pro, and ZB Bridge series, as well as SmartThings v3 and Home Assistant via ZHA or Zigbee2MQTT. When a leak is detected, you will receive push notifications through the app, though you can also set up local Zigbee scenes to trigger a gateway alarm if your WiFi connection fails. This makes it a reliable choice for monitoring areas like kitchens, bathrooms, or laundry rooms where early detection can prevent significant water damage.
