AliexpressThe SONOFF Hydro DUO US Smart Water Valve provides two independently controlled irrigation outlets in one valve body. It includes a flow meter and supports up to six schedules per channel, making it suitable for separating watering zones when the installation and control system match your setup. This listing concerns the US option, manufacturer model SWV-ZF2U, rather than the European-thread version referenced by the wider product-family title.
Control and irrigation functions
The valve communicates through Zigbee 3.0 and Bluetooth Low Energy proximity communication. Remote integration requires a compatible gateway or system; a hub is not promised as included. It is not a native Wi-Fi valve or a standalone native Matter valve. Matter access requires an appropriate bridge. The two outlets can be managed independently, while the flow meter provides water-flow information for the connected irrigation setup.

Limitations and installation notes
Install the valve vertically when relying on flow measurement. Low-flow systems below 5 L/min can trigger no-water detection, so check the behavior of your particular irrigation arrangement before depending on unattended watering. Protect the valve from freezing. Batteries, a USB power supply, cable, irrigation hoses and a gateway are not promised as included.
Buying checks for the US option
Confirm that your faucet and hose use the North American NH3/4-11.5 thread. The product-family title also references SWV-ZF2E, but the selected US option maps to SWV-ZF2U and is not the EU BSP G3/4-14 version. Review the selected bundle carefully: optional bundles or accessories should not be assumed from product imagery. For general marketplace delivery information, see AliExpress shipping to the US.
