The Shelly Leak Sensor Cable is an extension accessory for the Shelly Flood Gen4, designed to expand water leak detection coverage across larger areas. The cable detects water along its entire length, allowing flexible placement around appliances, pipes, and room perimeters.

With a 2 m cable length that can be extended up to 150 m using additional cables, it enables wide-area monitoring for spaces such as kitchens, basements, utility rooms, or plant areas where leaks may occur.
