Flood sensor Sonoff SNZB-05P

Description

Sonoff SNZB-05P – Zigbee 3.0 flood sensor

Smart water leak detection for complete protection of your home
Sonoff SNZB-05P is a Zigbee water leak sensor, designed to instantly detect minimal levels of liquid and automatically trigger alerts or preventive actions. Ideal for bathrooms, kitchens, technical rooms or basements, this sensor keeps your home safe even when there is no Wi-Fi connection.

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.

Ultra-sensitive detection

The smart probe detects water from as little as 0,5 mm, with a special design that allows installation even on metal surfaces – without false triggers.

Support for an extended detection cable

It can be used together with an extension cable (available separately) to cover large areas or hard-to-reach spaces. The cables can be connected in series with no length limit.

Instant alerts and offline operation

You receive push notifications in the eWeLink app in the event of a leak. And if the internet goes down, the local Zigbee scene still activates the audible alarm via the gateway.

Extended compatibility

Works with Zigbee 3.0 hubs, including:
Sonoff NSPanel Pro
Sonoff ZB Bridge / ZB Bridge-P / ZB Bridge-U
Sonoff iHost
SmartThings Hub v3
Home Assistant (via Zigbee2MQTT or ZHA)

Battery life of up to 5 years

The sensor is powered by a CR2477 battery (included), offering a service life of more than 5 years, with no maintenance worries.
