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.\u003c\/p\u003e\u003cp\u003eBuilt 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.

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.
