• 
  leak and drip detectionThe raised probe design allows liquid to be detected at a level of just 0.5 mm and also works on metal surfaces without false alarms due to the metal. The concave water collector detects drips and stops leaks at the source.

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

• Real-time alerts and multiple notification types
  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 failure.

• 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.

• Support for Home Assistant
  Easy integration into Home Assistant via ZHA or Zigbee2MQTT (Zigbee dongle 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 leak detection prevents costly repairs, mold growth, and protects your health.
• Flooding in the basement during heavy rain can damage floors, walls, carpets, and electrical equipment.
• Leaks in the HVAC system in the attic can cause insulation to rot, load-bearing problems, and health risks.

Unexpected leaks that can flood your home

• Pipes bursting due to freezing
• Old and worn pipes
• Washing machine leaks
• Dishwasher leaks
• Aging water heater

Multiple detection methods 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 alarms.

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

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

Designed for durability and quality

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

Reliable alerts and integration

Multiple notification types

• Push notifications in the app
• Alarm sound via Zigbee router
• Email notification (eWeLink advanced subscription required)

Redundant alerts
The sensor reports leaks every 10 minutes to prevent missing alarms due to network fluctuations.

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

Support for multiple platforms

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.
