Smart ZigBee Water Leak and Water Shortage Sensor E13, TUYA

Aprašymas

Smart Water Leak Sensor NOUS E13, ZigBee, TUYA

NOUS E13 is a smart ZigBee water leak sensor designed to help quickly detect the presence of water and reduce the risk of potential damage. When a leak is detected, the sensor activates an audible alarm of more than 80 dB and can send a notification to your phone via the TUYA smart home system.

The compact NOUS E13 can be used near a washing machine, dishwasher, water heater, sink, pipes or other locations where water leaks may occur. Water detection contacts are located on the bottom of the sensor, and the device also supports connection of a 1 metre detection cable, allowing the monitoring area to be adapted to a specific location.

NOUS E13 uses ZigBee 3.0 connectivity, so a compatible TUYA ZigBee gateway is required for smart functions. Once the sensor is connected to the “Nous Smart Home” system, you can monitor its status and battery level in the app and receive notifications. The IP66 protection rating helps protect the housing against dust and water.

Who Is This Product For?

The NOUS E13 water leak sensor is suitable for locations where even a small water leak could cause damage or remain unnoticed for a long time.

• Home and apartment owners who want additional protection against unexpected water leaks.
• Kitchens and bathrooms where there are numerous potential sources of water leaks.
• Washing machine and dishwasher areas where a damaged hose or connection may cause water leakage.
• Holiday homes and less frequently occupied properties where remote notifications about detected water can be particularly useful.
• TUYA smart home users who want to integrate a water leak sensor into a complete ZigBee automation system.

Practical Applications in the Kitchen, Bathroom and Boiler Room

• Place the sensor under a sink, near water supply pipes and connections.
• Use it near a washing machine to detect water from a damaged hose or leaking connection more quickly.
• Install it near a dishwasher or under kitchen furniture where water leaks may be difficult to notice.
• Use it near a boiler, water heater or other water system equipment.
• Use the 1 metre detection cable when you need to monitor a longer area or a location where the sensor itself cannot fit.
• Include the sensor in TUYA automation scenarios together with other compatible smart home devices.

Detect a Water Leak Before It Becomes a Major Problem

A small water leak under a washing machine, dishwasher or sink can remain unnoticed for a long time. During this period, moisture can damage floors, furniture or other structures. NOUS E13 is designed to detect the presence of water and immediately provide an audible warning.

When the sensor is connected to a ZigBee smart home system, local warnings are supplemented by phone notifications. This is particularly useful when you are away from home. When compatible TUYA automation devices are used, a water detection signal can also be used as a trigger condition for a smart automation scenario.

Technical Specifications

Frequently Asked Questions (FAQ)

How does the NOUS E13 water leak sensor work?
When water reaches the sensor's detection contacts or the connected detection cable, the sensor detects the leak and activates the audible alarm. The information can also be transmitted to the “Nous Smart Home” app via the ZigBee gateway.

Does NOUS E13 have an audible alarm?
Yes. The sensor has an integrated audible alarm of more than 80 dB, so it also provides a local warning when water is detected, even if you are not looking at your phone.

Does NOUS E13 require a ZigBee gateway?
Yes. A NOUS E1, NOUS E7 or another compatible TUYA ZigBee gateway is required for smart functions. The sensor itself does not connect directly to a Wi-Fi network.

Where is the best place to use the water leak sensor?
It can be installed near a washing machine, dishwasher, sink, water heater, pipes and other locations where there is a risk of water leakage. The sensor contacts or detection cable should be positioned where leaking water will reach them as early as possible.

What is the 1 metre detection cable used for?
The cable allows you to increase the monitored area or detect water in harder-to-reach locations. This is particularly useful under kitchen furniture, near pipework or behind household appliances.

What batteries does NOUS E13 use?
The sensor requires two AAA batteries. Their status can be checked in the “Nous Smart Home” app.

Choose the NOUS E13 smart ZigBee water leak sensor if you want to detect water more quickly under a washing machine, dishwasher, sink or near other potential leak sources. The audible alarm, 1 metre detection cable, IP66 protection and TUYA ZigBee system support provide a practical early warning solution for homes or other premises.
