SONOFF / 3 lines, 6 models / 2026
Last checked
SONOFF's Zigbee valve range is the Hydro series plus the earlier hose-end Zigbee Smart Water Valve.
The Hydro DUO has two channels and a flow meter, the Hydro ONE has a flow meter and the Hydro ONE Lite has none. Hydro valves also list a proximity mode that keeps basic control available without a gateway. The SenseGuard Indoor Siren (SNZB-09P) and the Micro Zigbee USB Smart Adaptor (ZBMicro) are separate Zigbee products. All of them need a Zigbee hub, gateway or coordinator.
