Short description

Shelly Flood Gen4 is a smart leak detection sensor that alerts you immediately when water is detected where it
shouldn’t be—under appliances, sinks, or along pipes. Featuring an innovative extendable leak sensor cable that
covers large areas (up to 150 m), it ensures wide protection against flooding. The device provides instant
notifications, local buzzer alerts, and supports multiple connectivity options (Wi-Fi, Zigbee, Bluetooth, and Matter).
Its IP44-rated housing ensures reliable operation even in humid environments.
