Water Shutoff Valve
A water shutoff valve closes the main water supply on command. Paired with leak sensors, it stops a burst hose or a failed fitting within seconds instead of waiting for someone to get home.

Its Z-Wave thermostats, sensors and water valves are ordinary Z-Wave Plus devices that Home Assistant drives locally through Z-Wave JS. Everything else, from the cameras and doorbells to the commercial access control and fire range, is licensed to the Alarm.com cloud, and reaches Home Assistant only through an unofficial integration or not at all.

ADC-SWM150
A motorised 1-inch shutoff valve with a flow meter in the same body, speaking Z-Wave Plus with S2. Home Assistant can include it directly in Z-Wave JS, which puts whole-home water shutoff and consumption data on the mains without an Alarm.com account.
ADC-SWV100
The current Alarm.com water shutoff: a motorised 1-inch valve on Z-Wave Plus with S2, but without the flow meter the older ADC-SWM150 carried. Home Assistant can include it in Z-Wave JS and close the mains from an automation.
