Sonoff Zigbee Smart Water Leak Sensor<\/p>\n
Flood and Drip Detection – The raised sensor design detects liquid levels as low as 0.5 mm and operates reliably even on metal surfaces without false triggering. Its concave water collection structure quickly detects drips and stops the leak at the source.<\/p>\n
Extended Detection Capability – Supports the connection of water leak detection cables (sold separately or as part of the sensor system). Whether wide area or focused spot coverage is required, the sensor accurately detects leaks. Extension cables can be daisy-chained without length limitation.<\/p>\n
Real-time and multiple alerts – Instant notifications in the app are sent as soon as water is detected. Local Zigbee scenes can trigger alarms on the control gateway even when the WiFi network is unavailable.<\/p>\n
Zigbee 3.0 Compatible – Connects to Zigbee 3.0 hubs such as SONOFF NSPanel Pro, SONOFF iHost, ZB Bridge versions (ZB Bridge, ZB Bridge-P, ZB Bridge-U) and SmartThings Hub V3.<\/p>\n
Home Assistant Support – Easily interfaces with Home Assistant via ZHA or Zigbee2MQTT (requires a Zigbee dongle such as SONOFF ZBDongle-P or ZBDongle-E) for seamless home automation.<\/p>\n
Sonoff Zigbee Smart Water Leak Sensor
\nSonoff Zigbee SNZB-05P Smart Water Leak Sensor is an advanced solution for protecting your home or office from leaks and flooding. The sensor detects water as deep as 0.5mm thanks to its raised probe design and concave structure to collect drops, enabling a quick response at the beginning of a leak. It is suitable for placement near washing machines, dishwashers, refrigerators, water heaters, sinks and bathrooms \u2013 and provides real-time alerts as soon as a leak is detected.<\/p>\n
With Zigbee 3.0 technology connection, the sensor easily integrates with smart home hubs such as SONOFF NSPanel Pro, SONOFF iHost, ZB Bridge Pro, ZBDongle-E, and also with SmartThings Hub. When water is detected, it can be configured to trigger smart scenes: closing a smart water valve, triggering an alarm, sending instant notifications to the app, and even automatically taking pictures on security cameras. Even if the WiFi network drops \u2013 local Zigbee scenes continue to work, ensuring continuous protection.<\/p>\n
The sensor comes with high water and dust resistance IP67, powered by a CR2477 battery that lasts up to 5 years of reliable use, and supports the possibility of connecting extension cables to detect water in a wider area without length limitation. Thanks to its compact design, light weight and simple installation, it is one of the most convenient and reliable solutions for protecting your home from expensive damage caused by water leaks.<\/p>\n
