Shelly Leak Sensor Cable 2m Extension for Flood Gen4 Water Detection
Protect your home from water damage with the Shelly Leak Sensor Cable, a 2-meter extendable water detection cable designed for use with the Shelly Flood Gen4 smart sensor. This cable detects water the moment it touches any part of the cable, providing comprehensive coverage for basements, kitchens, laundry rooms, garages, and hard-to-reach areas where leaks can cause costly damage. Multiple cables can be connected to expand coverage up to 490 ft. (150 meters), making it ideal for large properties, holiday homes, and commercial applications.

Perfect for Multi-Zone Water Leak Protection
The Shelly Leak Sensor Cable transforms your Shelly Flood Gen4 into a comprehensive perimeter water leak detection system. Unlike point sensors, this cable allows for the detection of water presence along its entire length, offering continuous and effective coverage in large or hard-to-reach areas. Monitor under sinks, behind washing machines and dishwashers, along basement walls, around water heaters, and in any location where a slow leak could go unnoticed until it causes serious damage.
Installation & Compatibility
Installation is simple and flexible. The 3.5mm jack plugs directly into Shelly Flood Gen4, another leak sensor cable, or an extension cable. The soft, flexible construction makes it easy to route around corners, under cabinets, and through tight spaces. Optional mounting brackets (3D print files available from Shelly) help secure the cable flat against surfaces for optimal water contact and reliable detection.
Smart Automation & Instant Alerts
When paired with Shelly Flood Gen4, the Leak Sensor Cable enables powerful smart home automations. Receive instant alerts on your mobile device the moment water is detected, trigger local alarms, automatically shut off water valves, or activate other connected devices to minimize damage. The system works with all major smart home platforms including Wi-Fi, Zigbee, Matter, and Bluetooth protocols.
