Smart water leak detector SHELLY Flood Gen4 WiFi ZigBee

Product detailed description

Shelly Flood Gen4 is a flood sensor that detects water exactly when it appears - under the dishwasher, washing machine, boiler or in the basement. With a long-range detection cable, built-in audible alarm and instant alerts, it helps prevent costly damage, and its compatibility with platforms such as Apple HomeKit, Google Home and Home Assistant makes it easy to integrate into an existing smart home system. In addition, battery power and IP44 protection allow installation in locations without access to an electrical outlet and with high humidity.

Flood and rain detection modes
The device offers two modes of operation, so you can easily adapt it to your specific application. Flood detection is designed for critical areas - as soon as the sensor detects water on the line, it immediately triggers an alarm that works well under the washing machine, dishwasher, boiler or in the basement. Rain detection works in a more subtle way: it registers rising moisture levels on surfaces but does not trigger an alarm, which works well on patios or under sheds, for example. In this mode, the device reacts at the first sign of precipitation and helps protect outdoor equipment and furniture.

Precision detection cable for small and large spaces
The two-meter flood detection cable provides a much greater range than a standard point sensor. It allows monitoring to cover hard-to-reach areas and its linear design is particularly suitable for long stretches of pipework, built-in furniture or large utility areas. If required, you can link consecutive sections to achieve a total length of up to 150 m, allowing you to protect large areas or several points at once.

Connectivity via Wi-Fi, Bluetooth, Zigbee and Matter
The Shelly Flood Gen4 sensor works with a variety of communication protocols (Bluetooth, Wi-Fi, Zigbee) and is compatible with the Matter standard, allowing for flexible integration with virtually any home automation system. You can easily connect it to Apple HomeKit, Google Home, Home Assistant, Samsung SmartThings or Amazon Alexa - manage all your devices from a single app!

Three alarm styles for different operating scenarios
The Shelly Flood Gen4 has a built-in audible alarm that emits a long alert when flooding is detected and a short beep when the battery is low. The sensor also offers three alarm modes that allow you to customize the water leak alert to your location. Intensive provides a quick and clear alert, Normal works well for everyday use, while Economy reduces power consumption, which is especially useful in summer homes, garages or other infrequently visited properties.

Battery power and freedom of installation
The device is powered by four 1.5 V AA batteries, which are included in the package. It requires no wiring and can be placed where there is no access to an outlet - for example, under the kitchen counter, in cabinets, near pipes or in utility areas. The device also has an IP44 rating, which means it is resistant to moisture and splash water. As a result, the sensor will work well not only indoors, but also in semi-open spaces, such as on terraces or under sheds.Note: do not expose the device directly to rain - the main module should be shielded and only the detection cable should be exposed.

Local automation and cooperation with external devices
The Gen4 Flood Sensor supports local operating scenarios that, among other things, allow the device to automatically shut down when water is detected. Integration with other Shelly modules and third-party devices allows for the creation of room- or system-specific safety features.

Control via app and built-in web interface
Flood Gen4 devices can be controlled using the Shelly Smart Control app and Shelly Cloud, which allows remote access to the device from anywhere. In addition, it has a built-in web interface that makes it easy to configure, monitor and customize settings. No matter how you work, you are always in full control of the sensor's performance.

Wide range of applications
The Shelly Flood Gen4 sensor will work well in many locations where the risk of water flooding is extremely high. Under the dishwasher, washing machine, boiler or in the bathroom, the sensor will detect even small water leaks before they cause costly damage. Deployed along pipes, it can monitor long stretches of water pipes, and in basements or garages, it reacts at the first sign of flooding. Thanks to its rain detection mode, it can also be used in semi-open areas such as patios or under sheds, where it responds to sudden rain and protects garden furniture. The device will also prove its worth in holiday homes and less frequently visited properties, where the energy-saving mode allows several months of operation with minimal energy consumption.
