Flood sensor Sonoff SNZB-05P, with flood detection cable included
Description
Note: This product uses the Zigbee protocol and requires a compatible Zigbee hub/bridge (e.g. Sonoff ZBBridge-P / Sonoff ZBBridge-U / Sonoff ZBDongle-E / Sonoff Dongle-M) to be connected to the network and controlled from the app. It does not work on its own over WiFi.
Sonoff SNZB-05P – Zigbee 3.0 water leak sensor with detection cable included
Smart protection against water leaks, with instant notifications and extended detection
The Sonoff SNZB-05P is an advanced Zigbee sensor for detecting water leaks, designed to prevent flood damage by automatically triggering alerts and smart scenes. This model comes with the detection cable included, ideal for large or hard-to-reach areas.
Ultra-sensitive detection, even of drops
The sensor probe detects liquid from 0,5 mm, and the concave design collects water efficiently, providing a fast reaction to leaks or dripping. It also works on metal surfaces without false alarms.
Detection cable included for extended coverage
Ideal for large areas or hard-to-reach corners, the included cable can be extended in series, with no length limit. It detects leaks wherever you place it.
Real-time notifications and alerts
You receive instant push notifications in the eWeLink app at the first trace of water. In addition, you can trigger local smart scenes (audible alarm via the gateway) even without a Wi-Fi connection.
Compatible with Zigbee 3.0 and Home Assistant
Works with Zigbee 3.0 hubs such as:
Sonoff NSPanel Pro
Sonoff ZB Bridge / Bridge-P / Bridge-U
Sonoff iHost
SmartThings Hub v3
Home Assistant via ZHA or Zigbee2MQTT (with ZBDongle-E / ZBDongle-P)
Battery life of up to 5 years
Powered by a CR2477 battery (included), the sensor offers a service life of up to 5 years, with no maintenance worries.
The Sonoff SNZB-05P, with the detection cable included, is the complete solution for smart protection of your home against floods and water leaks!
Practical use cases
