Sonoff Hydro ONE: Smart Zigbee 3/4 Water Valve with Flowmeter for Irrigation
Managing irrigation no longer has to mean manually turning the faucet on and off or relying on inflexible timers. Sonoff Hydro ONE is a 3/4 Zigbee smart water valve designed to automate the irrigation of gardens, lawns, vegetable gardens, greenhouses, terraces and outdoor areas, offering precise control directly from the app. The European version SWV-ZFE uses a G3/4-14 BSP connection, compatible with most garden faucets in Europe. Thanks to the integrated flow meter , Hydro ONE allows you to monitor water consumption, control irrigation duration and consult history for up to 6 months , helping to reduce waste and costs. You can create customized time, volume or cyclical programs, set frequencies on specific days, activate the rain delay and adjust irrigation based on the season or weather conditions. Zigbee 3.0 + BLE connectivity allows use with compatible gateways for remote control, smart scenes and notifications, or in proximity mode when a stable Zigbee signal is not available. With IP55 protection rating, brass water inlet, 4 AA battery power supply and alerts for low battery, leak, low water and frost risk, Sonoff Hydro ONE is a complete solution to make outdoor irrigation more automatic, safe and efficient.
Smart water management with timers, notifications, and app control
Manual irrigation management becomes simpler and smarter with Sonoff Hydro ONE , the smart Zigbee water valve designed to overcome the limitations of traditional, non-connected faucets. In addition to manual opening and closing, it allows you to create irrigation schedules, activate rain delays, remotely control water usage, and view consumption history. Advanced features such as anomaly alerts, weather-based adjustments, seasonal adjustments, and child lock help you use water more conveniently, safely, and efficiently, whether in the garden, on terraces, vegetable gardens, or greenhouses.
Proximity mode without Zigbee gateway
Even when the Zigbee gateway is unavailable or the signal doesn't reach the installation point, Sonoff Hydro ONE can still be managed via proximity mode . By holding your smartphone close to the valve, you can access essential functions from the eWeLink app, control irrigation, and change key settings without having to constantly rely on the Zigbee network.
A smart valve for your garden, lawn, vegetable garden, and pool
From lawn care to vegetable garden irrigation, Sonoff Hydro ONE adapts to many outdoor applications with a single compact solution. It can be installed on 3/4" garden faucets to manage sprinklers, flower beds, greenhouses, home gardens, and pool systems. The Zigbee smart valve allows you to program watering based on actual needs, avoiding unnecessary manual opening and making it easier to keep plants, lawns, and green spaces always well-maintained.
3/4ā brass inlet and quick installation on external tap
Designed to last outdoors, Sonoff Hydro ONE features a more robust brass water inlet than traditional plastic fittings, ideal for frequent connections to garden faucets, irrigation systems, terraces, and vegetable gardens. The European version uses a G3/4" connection, compatible with most standard faucets, and installs in minutes without any masonry or electrical wiring. For more accurate water flow measurement, vertical installation is recommended, so the valve can better track consumption and manage smart irrigation more reliably.
Precise irrigation by time, cycle or water volume
Scheduling irrigation becomes much more precise thanks to Sonoff Hydro ONE 's advanced modes. You can create up to 6 smart programs , choosing between duration-based irrigation, cyclical irrigation with pauses and restarts, or irrigation based on the desired water volume. This management helps distribute water more evenly across the lawn, vegetable garden, greenhouse, and flowerbeds, avoiding waste and reducing the risk of over- or under-watering. The failsafe function automatically interrupts the cycle if the set volume is not reached within the time limit, protecting the program from low pressure or insufficient flow problems.
Customizable irrigation frequency for every need
Every garden has different rhythms: with Sonoff Hydro ONE, you can precisely choose when to activate irrigation , adapting programs to the actual needs of your lawn, vegetable garden, terrace, or greenhouse. The smart valve allows you to set odd/even day cycles, programmable intervals from 1 to 30 days , or customized calendars, so water is delivered only when needed.
Seasonal irrigation adjustments for healthier plants
As the seasons change, so do your plants' water needs. Sonoff Hydro ONE allows you to adjust irrigation based on the time of year, increasing or decreasing the duration and volume of water with customizable seasonal multipliers. In summer, you can increase watering for your lawn, vegetable garden, and garden; in spring or fall, you can reduce it to avoid waste; and in the colder months, you can suspend cycles when irrigation is not needed.
Intelligent irrigation with rain delay and frost protection
When the weather changes, irrigation needs to adapt too. Sonoff Hydro ONE can automatically suspend scheduled programs for the next 24 hours in the event of rain, high humidity, or low temperatures, preventing water waste and protecting the system from adverse conditions. Using the app, you can set custom thresholds for rain delay, humidity delay, and frost delay, so the smart valve regulates watering more precisely than a traditional timer.
Advanced protection with child lock and automatic alerts
Automatic irrigation safety is managed by features designed to prevent errors, waste, and unwanted activations. Sonoff Hydro ONE integrates a child lock , which disables local buttons and allows control only via the app, also useful for preventing accidental activation by pets or children. The system also sends notifications in the event of low battery, low water, leaks, or risk of frost , so you can intervene quickly before the problem becomes more serious. In the event of abnormal flow or water shortage, the valve can automatically close, making irrigation more reliable and worry-free.
Irrigation history and water consumption always under control
Each irrigation cycle is recorded to help you understand how much water you use, when it is distributed, and if there are any anomalies in the system. With Sonoff Hydro ONE, you can consult the history by day, month, or semester via the app, monitoring water volume and irrigation duration with clear, easy-to-read graphs. This feature is very useful for identifying unusual consumption, optimizing programs, reducing waste, and managing your garden, lawn, vegetable patch, or greenhouse with greater precision. The integrated flow meter also allows you to monitor up to 6 months of history , making smart irrigation more efficient and informed.
Voice control and smart scenes for multi-zone irrigation
Managing multiple green areas becomes much more convenient thanks to Sonoff Hydro ONE 's smart connectivity. By installing multiple valves in your garden, lawn, vegetable patch, or pool area, you can create customized scenarios from the eWeLink app and control each irrigation point separately. With a compatible Zigbee gateway, the valve can also integrate with Alexa, Google Home, and SmartThings , allowing for quick voice commands like turning the water on or off in a specific area.
Apple Home compatibility via Matter Bridge
Those who use the Apple ecosystem can integrate Sonoff Hydro ONE into Apple Home via a compatible Matter Bridge , keeping the Zigbee valve within a more open and centralized home automation system. Using devices like ZBBridge-U , iHost , NSPanel Pro , or solutions with eWeLink CUBE , the valve can be managed together with other smart home accessories, creating more comprehensive automations.
Open-source integration with Home Assistant and Zigbee2MQTT
For those using advanced home automation, Sonoff Hydro ONE can also be integrated into open-source environments based on Zigbee 3.0 , such as Home Assistant and Zigbee2MQTT , extending control possibilities beyond the eWeLink app. This compatibility allows you to monitor status, battery, signal quality, and valve control directly from your home automation dashboard, creating customized automations for irrigation, water saving, and multi-zone management.
