Detects water leaks, freezing and humidity in homes and buildings and automatically shuts off the water supply.


Operators responsible for household and building plumbing, water supply lines, wet rooms, appliances, shut-off valves, floors, and connected leak sensors cannot continuously inspect every operating condition or developing fault. Periodic checks leave gaps between readings, while isolated local indicators provide limited history and context. A late response can cause downtime, safety exposure, equipment damage, or incomplete compliance evidence. Teams need timely measurements, clear exceptions, and a defined operating response.
Waterguard+ Connected Water Leak, Freeze and Humidity Protection combines connected field data with application software. Wireless sensors detect escaping water, moisture, freezing temperatures and humidity across the property. The AbraOS hub and cloud evaluate readings against safe limits, recognize leaks or freeze risk, and trigger the shut-off valve. Stop the water supply automatically, alert residents and partners, and prevent costly water damage before it spreads.
Teams configure the monitored assets, users, and operating rules. Wireless sensors detect escaping water, moisture, freezing temperatures and humidity across the property. Wireless sensors report to an in-home AbraOS hub and cloud; residents receive app alerts and the shut-off valve closes automatically when a leak is detected. The AbraOS hub and cloud evaluate readings against safe limits, recognize leaks or freeze risk, and trigger the shut-off valve. Stop the water supply automatically, alert residents and partners, and prevent costly water damage before it spreads.
