Complete Leak Protection-At Home or Away
Perfect for: Under sinks, dishwashers, or washing machines
Place Shelly Flood Gen4 beneath appliances that commonly develop leaks like your dishwasher or washing machine. Its extendable leak sensor cable allows you to cover a larger area, detecting water the moment it appears. Receive real-time alerts on your phone and activate local alarms to prevent long-term damage before it starts.
Want even more peace of mind? Pair it with Shelly 1 Gen4 or the Frankever Smart Water Valveâ¯to automatically shut off your home's water supply when you're away. With local automation and scripting, the system protects your home 24/7-even without internet.
Peace of Mind for Your Vacation Property
Perfect for: Vacation homes, cabins, and remote properties
Don't let a minor leak ruin your next getaway. Shelly Flood Gen4 is battery-operated and offers uninterrupted monitor & control via Shelly Smart Control app or other home automation platforms.
Install it in seasonal homes or cabins and activate "Economic Alarm Style" to minimize battery drain while keeping your space protected-even when left unattended for months.
Secure Your Basement or Garage from Flood Damage
Perfect for: Basements or garages
Basements or garages are among the most vulnerable parts of any home. Install Shelly Flood Gen4 in corners or along pipes where flooding might occur. Thanks to its customizable alert modes and extended coverage, you'll be notified immediately of leaks, even if you're not home, helping you act fast and avoid costly repairs.
Protect Outdoor Furniture with Automated Rain Detection
Perfect for: Patios, decks, and garden seating areas
Outdoor lounging spaces can be quickly ruined by unexpected rain. Using Rain Mode, Shelly Flood Gen4 detects the early signs of rainfall by sensing rising humidity levels on its surface — a reliable indicator before water visibly accumulates. When paired with Shelly 2PM Gen4 to control your motorized awning, it can automatically extend the cover to shield your furniture the moment rain begins.
