The Shelly Flood S Gen4 is a compact wireless water leak sensor that immediately alerts you when water is detected. It detects not only tap water but also clean, low-conductivity water such as air conditioner condensate or distilled water, helping to prevent costly water damage.
In addition to water leak detection, the Shelly Flood S Gen4 features an integrated temperature sensor. This makes it suitable for monitoring the ambient temperature in technical rooms, basements, utility rooms and other sensitive areas.
The sensor supports Wi-Fi, Zigbee, Bluetooth and Matter. Depending on your preferred setup, communication can be configured via either Wi-Fi or Zigbee. Notifications and automations can be managed through the Shelly Smart Control app or a compatible smart home platform.
With its IP67 protection rating, the Shelly Flood S Gen4 is designed for use in humid environments. It operates on one included CR123A battery with a battery life of up to 2 years and can easily be placed underneath washing machines, dishwashers, boilers and other appliances.
