A worn gasket drips overnight and the cable detects water the instant it touches any section.
Lay the cable around the perimeter of the room with the boiler and water manifold.

Shelly Leak Sensor Cable is a 2 m rope leak detection cable designed as an accessory for the Shelly Flood Gen4 sensor. Unlike a single-point probe, this cable senses water the moment it touches any section along its full length, so you can protect entire runs - behind the washing machine, along the boiler or around the perimeter of a cellar.<br><br>The cable is 4 mm in diameter, weighs 37 g and is made of conductive polymer and insulated polymer in a black-and-white finish. Thanks to connectors at both ends you can chain several Leak Sensor Cables or extension cables together for up to 150 m of continuous detection without any extra power supply. It operates between -20 C and 40 C, which suits technical rooms and basements in Chisinau.<br><br>As a passive accessory the cable has no radio of its own - all alerts and automations are handled by the Shelly Flood Gen4 it is connected to.
Lay the cable around the perimeter of the room with the boiler and water manifold.
Route the cable along the wall behind the washing machine and dishwasher.
Chain several cables together for up to 150 m of coverage along the walls.
