## Summary description

Shelly Flood Gen4 is a wireless flood sensor compatible with WLAN and Matter ecosystems. It detects water leaks and notifies users for fast response. Designed for home and commercial use, it offers flexible power options (mains or battery) and simple integration into smart home setups for prevention of water damage and automated responses.

## Long description

Shelly Flood Gen4 is a compact wireless water leak detector designed for integration into WLAN and Matter smart home ecosystems. The device senses the presence of water on floors or surfaces, sends immediate alerts to connected systems, and supports both mains and battery power options for flexible installation in homes or commercial premises.
Advantages
The sensor combines dual connectivity with low-power operation, enabling reliable detection and timely notifications through WLAN and Matter-compatible platforms. Its dual power support allows continuous monitoring when mains power is available and battery backup for locations without a nearby outlet. The device is compact and easy to position near potential leak sources and is designed for simple integration into automated workflows to trigger alarms, shutoff valves, or other protective actions.
Suitable for
Basements and crawl spaces prone to flooding
Under sinks, near washing machines and dishwashers
Boiler rooms and utility closets
Commercial storage areas and server rooms with potential water damage risk
Smart home setups requiring automated leak responses
Key specifications
Connectivity: WLAN and Matter compatibility for integration with smart home platforms
Power options: mains power with battery backup or standalone battery operation
Detection type: water presence detection on contact points/surface sensors
Installation: surface-mountable compact design suitable for floor or raised placement
Notification: real-time alerts to connected applications and automation systems
How to use
Place the Flood sensor on a level surface near potential leak sources such as appliances, pipes, or drains. For permanent locations with power access, connect to mains and configure the device through the compatible WLAN or Matter setup app; for remote or temporary placements use the battery option and follow the pairing procedure. Calibrate or test the sensor after installation by simulating a small amount of water at the sensing points to confirm alert delivery and automation triggers. Ensure the device remains accessible for occasional inspection and battery replacement if operating on battery power.
Usage recommendations
Position the sensor where leaks are most likely to appear, avoid placing it on sloped or highly insulating surfaces that prevent water contact, and maintain a clear communication path to the WLAN hub or Matter controller. Regularly verify firmware updates and test alerts to ensure reliable operation.
