Waterguard watches every WaterSensor+ in your home and shuts the main valve the moment water is detected, stopping a small leak from becoming an expensive flood. Temperature, humidity and battery level for each wireless sensor are there at a glance, and the shut-off valve can be opened or closed from any Flow.
It talks to your Abra Linkbox+ directly over the local network, so your leak protection keeps working even when the internet does not.
