Product detailed description
💧 Protect Your Home 24/7 with the Shelly Flood Gen4 Sensor
The Shelly Flood Gen4 stands out with its multi-protocol connectivity—supporting Wi-Fi, Bluetooth, ZigBee, and Matter, ensuring broad compatibility with various smart home systems. Battery-operated and requiring no wiring, it can be easily placed anywhere in your home. With Plug & Play technology, installation is fast and hassle-free.
It offers three selectable alert profiles (Intensive, Normal, and Eco), allowing you to optimize detection sensitivity and battery consumption. It works with major platforms such as Apple HomeKit, Google Home, Amazon Alexa, Home Assistant, SmartThings, and others (via MQTT).
Complete Water Leak Protection – At Home or Away
Place the Shelly Flood Gen4 under appliances prone to leaks, like dishwashers or washing machines. Its extendable sensor cable (up to 150m) allows it to cover a larger area and detect water the moment it appears. You will receive real-time notifications on your phone and can activate local alarms.
Want even more peace of mind? Pair it with a Shelly 1 Gen4 or a smart valve controller to automatically shut off the water supply when a leak is detected.
Peace of Mind for Your Vacation Home
Don't let a minor water leak ruin your getaway. Install the sensor in seasonal homes and activate Eco Mode, which minimizes battery consumption while ensuring your property remains continuously protected.
Protect Patio Furniture with Automatic Rain Detection
Outdoor relaxation zones can quickly be ruined by unexpected rain. Thanks to Rain Mode, the Shelly Flood Gen4 can detect the first signs of rain by measuring increasing moisture on its surface. When paired with a motorized awning (e.g., controlled by a Shelly 2PM), the canopy can automatically deploy the moment it starts to rain.
Note: The main unit itself is IP44 rated and must not be directly exposed to heavy rain. Place the sensor cable in the area where rain detection is required.
