Nous E13 Zigbee Water Leak or Shortage Sensor (Flood Detector)

Product detailed description

Nous E13 – Stop Flood Damage Before It Happens

The NOUS E13 (Zigbee) Water Leak Sensor is a compact, intelligent device that acts as a tireless guard for your property. It is engineered to detect unwanted water presence (from a burst pipe or a malfunctioning washing machine) and instantly alert you long before the flooding causes massive financial damage to your home and your neighbors.

Loud Built-in Siren and Extension Probe

This model distinguishes itself from other smart sensors on the market with a massive advantage: the main unit houses an exceptionally loud (80 dB) built-in siren alarm. Furthermore, the actual water detection does not happen on the main sensor body itself, but rather at the tip of the included 1-meter wire probe.
This brilliant design allows you to mount the main unit (and its loud siren) higher up on the wall where it can be heard clearly, while only dropping the small metal probe tip to the floor underneath your sink, bathtub, or behind the kitchen cabinets. Additionally, the device is designed to detect both the presence of water (leaks) and the absence of water (useful for monitoring empty aquariums or tanks).

Instant Smartphone Alerts and Automations

The moment the probe contacts water, the deafening siren triggers locally, and the device instantly fires a push notification directly to your smartphone. When integrated with other smart home actuators, it performs miracles: for instance, if the Nous E13 detects a leak, it can trigger an automation scene that commands a motorized smart valve (like the Nous LZ3) to immediately and physically shut off the house's main water supply line.

Long Battery Life and Wide Compatibility

The sensor is completely wire-free, powered solely by 2 standard AAA batteries that boast an exceptionally long lifespan. The sensor body itself carries a robust IP66 waterproof rating, ensuring it easily survives in highly damp and wet environments.

Important Note: Because this device utilizes the advanced Zigbee 3.0 communication protocol, you absolutely must own a central Zigbee Gateway (such as the Nous E1) to integrate it with the Nous Smart Home or Tuya (Smart Life) mobile apps. This sensor is also a favorite among tech enthusiasts for easy integration into open-source platforms like Home Assistant and Zigbee2MQTT.
