Extension Cable for Shelly Flood Gen4

Extend your Shelly Flood Gen4 setup with this 2m extension cable, extending coverage for larger or hard-to-access areas, delivering precise water leak detection around appliances, in basements, kitchens, garages, laundry rooms, holiday homes or any areas at risk.

You can connect multiple extension cables together up to 150m for massive coverage.

Shelly Flood Gen4 not included.

Extension use cases

• Run the leak-sensing cable neatly along a wall edge - mount the brackets along walls or wall sides to guide the Leak Sensor Cable in a straight line. With the cable held flat to the surface, your leak-detection setup can react more reliably when moisture reaches the cable.
• Secure the cable under a kitchen sink where hoses and fittings can drip - use multiple brackets to route the Leak Sensor Cable along the cabinet base or floor area so it doesn’t shift during cleaning or when items are moved. Keeping full surface contact helps ensure the cable is positioned to trigger your leak-alert routine as soon as water appears.
• Create a stable sensing path behind a washing machine or dishwasher - attach the brackets to guide the Leak Sensor Cable along the floor line behind appliances where vibration can otherwise move loose cables. A straight, held-down cable makes it easier to maintain consistent coverage for your leak-notification or monitoring rules.
• Route the cable along a basement wall or utility-room perimeter - place brackets at intervals to keep the Leak Sensor Cable tight to the floor or a flat ledge where seepage might first appear. With the cable secured, your existing leak-detection automations can depend on the cable staying in the intended detection zone.
• Fix the cable around a water heater, HVAC area, or other equipment footprint - use the pack of 10 to anchor the cable around the edges of a drip-risk zone so it remains flat and in continuous contact. This improves the chance that moisture reaching the area is detected promptly, enabling quicker response from your leak-monitoring setup.
