A battery-powered Zigbee 3.0 water valve for hose bibs and drip lines with built-in flow metering. Home Assistant opens and closes it through ZHA or Zigbee2MQTT, waters by duration or by measured volume, and flags water shortage or leakage, all local on your Zigbee mesh, with about 20 months from 4 AA batteries.

Roles it can fill
Zigbee2MQTT exposes valve state, flow rate, battery, water shortage/leakage status, cyclic timed and cyclic volume-based irrigation programs, and auto-close on prolonged water shortage (firmware 1.0.4+, OTA updatable); ZHA pairs it as a standard Zigbee valve. IP55-rated, 0.06–0.8 MPa working pressure, BSP or NH thread variants; pick NH for US garden hoses. About $27 from ITEAD.
