# SONOFF water valves, sirens and USB adapters

*SONOFF / 6 models / 2026*

> 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.
