Sonoff Hydro ONE SWV-ZFE - Smart Zigbee Irrigation Valve

Zigbee Irrigation Valve with Integrated Flow Meter for Garden

The Sonoff Hydro ONE SWV-ZFE is a battery-powered smart water valve designed to automate and optimize garden watering. Equipped with an integrated flow meter, it allows precise watering control, either by duration or by volume of water consumed. Ideal for gardens, lawns, vegetable patches, or small irrigation zones, with the robustness of a brass inlet and IP55 protection for outdoor use.

Main features

✔ Dual connectivity: Zigbee 3.0 and Bluetooth Low Energy for direct local control ✔ Integrated flow meter: watering by time or by water volume ✔ 6 smart schedules: configurable independent watering programs ✔ Weather adjustment: automatically skips watering in unfavorable conditions ✔ Seasonal adjustment: adapts duration and volume according to the season ✔ Real-time alerts: low battery, lack of water, leaks and frost risk ✔ Brass connector: durable, stable and crack-resistant ✔ History and statistics: daily, monthly and half-yearly consumption for download

Usage example

Install the Hydro ONE on the garden outdoor tap, connect it to your Sonoff Zigbee hub (such as the ZBBridge-P or NSPanel Pro) and configure up to 6 watering schedules in the eWeLink app. You can set watering by duration (e.g. 15 minutes at 7 a.m.) or by volume (e.g. 20 liters). On rainy days, the valve automatically skips watering, avoiding water waste. If the Zigbee signal is weak outdoors, use direct Bluetooth control up to 20 meters.
