Description
The SONOFF Hydro DUO (SWV-ZF2E) is a dual-channel Zigbee smart water valve with a built-in flow meter that manages two irrigation zones independently from a single tap. Each channel runs its own watering plan, with up to 6 schedules per channel and timed or volume-based watering.
It connects over Zigbee 3.0 and Bluetooth Low Energy (BLE), so schedules and manual control remain available through a proximity connection even without a gateway. Weather-based and seasonal adjustments save water, app alerts warn of low battery, frost, water shortage or leakage, and the IP65 housing with a brass inlet is built for outdoor use. This listing is the EU version (SWV-ZF2E).
Note: a Zigbee gateway is required for remote control and smart home integration (see "Works With" below). The EU and US versions have different inlet/outlet thread specifications and are not interchangeable.
