The Shelly Flood Gen4 is a smart, proactive flood sensor designed to detect leaks and water intrusion before they cause costly damage. Ideal for basements, kitchens, garages, laundry rooms, and holiday homes, it alerts you the moment water appears where it shouldn’t. Its standout feature is the extendable leak sensor cable, which monitors along a surface rather than a single point, giving you broader, more reliable coverage under appliances, along pipes, or across vulnerable areas. With instant mobile alerts and local alarms, you stay informed and in control whether you’re at home or away.
Built on Shelly’s latest Gen4 platform, the Shelly Flood Gen4 offers true multiprotocol flexibility with Bluetooth, WiFi, and Zigbee, plus full Matter certification for seamless integration into any modern smart home ecosystem. It supports both Flood Detection and Rain Detection modes, making it just as useful indoors as it is for sheltered outdoor setups. Three configurable alarm styles (Intense, Normal, and Economic) let you balance audibility and battery life to suit everything from primary residences to long-term vacant properties. Battery-powered operation with included AA batteries ensures uninterrupted protection even during power outages.
