Product information

Description

Nous E4 ZigBee 3.0 water sensor is a compact leak detection device designed for integration with ZigBee smart home systems. It senses the presence of standing water at floor level and transmits status updates and alarm events to a compatible ZigBee hub. The sensor is intended for locations where leaks may occur—near sinks, washing machines, boilers, water heaters and in basements or utility rooms—and enables automated responses such as notifications, alarms or shutoff actions when connected to a supported smart home controller.

Advantages

The device offers real‑time leak detection over ZigBee 3.0 for reliable communication with a wide range of hubs and controllers. Its compact design allows placement in confined spaces and along baseboards. Low power consumption supports long battery life, and simple integration enables use in automation scenes to trigger alerts or protective actions. The sensor operates without the need for direct wiring, simplifying installation and relocation.

Suitable for

Monitoring under kitchen and bathroom sinks
Placement near washing machines and dishwashers
Protection around boilers and hot water tanks
Basement, crawlspace or utility room leak detection
Integration into home automation scenarios for automatic shutoff or alarm

Key specifications

Communication protocol: ZigBee 3.0 compatible
Detection type: standing water / liquid contact detection
Power supply: battery powered for wireless installation
Form factor: compact sensor housing suitable for floor placement
Integration: reports events and status to compatible ZigBee hubs for automation

How to use

Place the Nous E4 sensor on a level surface where leaks or pooling water are most likely to occur, ensuring the sensing contacts can touch the floor. Pair the sensor with a ZigBee 3.0 compatible hub following the hub’s device inclusion procedure. Once paired, configure alarm notifications and automation rules in the hub or smart home app to receive alerts or trigger actions such as sirens, push notifications or valve shutoff when water is detected. Test the sensor after installation to confirm communication with the hub and correct alarm behavior.

Usage recommendations

Install the sensor on a clean, dry surface and avoid placing it directly on carpets or unstable substrates. Keep the device within the reliable ZigBee network range of your hub and avoid strong sources of radio interference. Periodically test the sensor and replace batteries according to the hub’s battery status reports to ensure continuous protection against leaks.
