The Leak Sensor Cable detects water the moment it touches any part of the cable – not just a single spot. Flexible and easy to install, it’s perfect for placing under appliances, along walls, or across larger areas that need extra protection. Originally included with Shelly Flood Gen4, it’s now available as a separate extension, allowing you to expand your coverage up to 150 meters. Just connect additional cables to protect every vulnerable area of your home with confidence. Extendable cable for expanded Shelly Flood Gen4 water detection Main Features Full-length detection – senses water along the entire cable for extended protection. Multi-water type detection – detects tap water, rainwater, AC leaks, and fire protection water. Expandable coverage – chain multiple cables for up to 150 m of continuous leak detection. High sensitivity – super-conductive materials provide fast and reliable response. Flexible design – soft cable adapts to tight or irregular spaces, easy to install anywhere. Reusable & low maintenance – simply dry with a cloth and reuse after an alarm.
