The Shelly Leak Sensor is an auxiliary sensing cable that can significantly extend the coverage of the Shelly Flood Gen4 water leak detector. The cable senses along its entire length, so it does not detect moisture at just a single point. It is ideal for protecting long wall sections, kitchens, bathrooms, mechanical rooms, laundry rooms, or even basements.

The cable is flexible, easy to lay, and reusable: after an alarm, simply dry it and it is ready for use again. It connects in a Plug&Play manner to the dedicated sensor port of the Shelly Flood Gen4 and requires no separate power supply. By linking multiple sections, the total monitored length can be extended up to 150 meters.

Use cases include the areas around dishwashers, washing machines, sinks, boilers, refrigerators, and plumbing; continuous, line-based leak detection along long walls or in hard-to-reach places.
