• Leak and drip detection
  The raised probe design allows liquid detection as low as 0.5mm and works on metal surfaces without false metal triggers. The concave water collector detects drips and stops leaks at the source.

• Extended detection support
  In combination with the leak detection cable (available separately or as part of a sensor kit), it enables detection over both wide areas and narrowly focused areas. The extension cable can be connected in series without limitation of the total length.

• Real-time alerts and multiple types of notifications
  The SNZB-05P water detection sensor immediately sends a notification to the app on your phone when a leak is detected. Local Zigbee scenarios can trigger an audible alarm via the router even in the event of a WiFi network outage.

• Compatible with Zigbee 3.0
  Works with Zigbee hubs that use the Zigbee 3.0 protocol, such as: SONOFF NSPanel Pro, SONOFF iHost, SONOFF ZB Bridge/ZB Bridge-P/ZB Bridge-U, SmartThings hub v3, etc.

• Home Assistant support
  Easy integration into Home Assistant via ZHA or Zigbee2MQTT (a Zigbee dongle is required, e.g. SONOFF ZBDongle-P or ZBDongle-E).
  
  Note : SNZB-05P must work in conjunction with a Zigbee hub.

Detect leaks in time, protect your home

• Early detection of leaks prevents expensive repairs, mold growth, and protects health.
• Basement flooding during rains can damage floors, walls, carpets, and electrical equipment.
• A leaking HVAC system in the attic can cause insulation rot, load-bearing issues, and health risks.

Unexpected leaks that can flood your home

• Pipe bursting due to frost
• Old and worn pipes
• Washing machine leak
• Dishwasher Leak
• Boiler aging

Multiple detection modes for different scenarios

Leak detection
The raised probe detects as little as 0.5 mm of liquid and also works on metal surfaces without false triggering.

Drip detection
The concave water collector detects dripping and stops it at the source.

Detection with extended cable
Allows for wide or targeted detection. Cables can be connected in series without length limitation.
In high humidity, the cable may trigger leak detection.

Designed for durability and quality

• IP67 water and dust protection – works even in humid or dusty environments.
• Gold-plated probes for better corrosion resistance (48-hour salt spray test).
• UV-resistant materials prevent discoloration in the sun.

Reliable alerting and integration

Multiple notification types

• In-app push notifications
• Alarm sound via Zigbee router
• Email notification ( eWeLink advanced subscription required )

Redundant warnings
The sensor reports leaks every 10 minutes to avoid missing an alarm due to network fluctuations.

Local Zigbee scenes
They work even when WiFi goes down – the alarm is still triggered via the Zigbee router

Multi-platform support

Compatible with:
Alexa , Google , SmartThings , IFTTT , Alice
( note: Alexa detects the sensor as a motion sensor )
SMS alerts are available with an eWeLink subscription and connection via IFTTT.
