Shelly Flood Gen4 Smart Water Leak Sensor

Shelly Flood Gen4 is a battery-operated water leak sensor for monitoring areas where a leak could cause damage. Its extendable sensor cable detects water along the cable, helping cover spaces beneath sinks, near appliances, in laundry areas, or around other vulnerable points. The device supports flood detection and rain detection modes and can send alerts through Shelly Smart Control or a compatible home automation platform. Shelly documents Wi-Fi, Bluetooth and Zigbee connectivity, together with Matter support, so the sensor can fit into different smart home setups. The enclosure has an IP44 protection rating. Local automation can trigger an action when water is detected, subject to the connected system and configured rules. Review placement, cable routing and battery access before setup. Use the supplied cable and follow the manufacturer’s installation guidance for reliable detection.
