Product detailed description

💦 Smart irrigation that saves your time and water

The Hydro ONE Zigbee water valve is a battery-powered smart irrigation valve  designed for outdoor use. It allows you to perform scheduled and automated watering tasks in gardens, lawns, vegetable patches, or smaller irrigation zones. Thanks to the built-in water flow meter, it supports not only time-based but also fixed-volume watering, allowing for more precise control over water consumption. It is especially useful for users who want consistent and predictable watering while reducing waste and minimizing manual intervention, or who simply don't have time for daily watering tasks. View your watering history by day, month, or half-year. Quickly detect abnormal watering, export records, and manage your irrigation like a pro.

One of the key advantages of the device is the support for both Zigbee 3.0 and nearby Bluetooth Low Energy connectivity for situations such as internet outages or a weak Zigbee signal. In Zigbee mode and when connected to a control unit (hub), the valve offers rich automation options. However, in local proximity mode within the eWeLink ecosystem, you can control it directly from your smartphone at a distance of 10 to 20 meters, entirely without a hub. This is extremely useful outdoors, where the Zigbee signal may be limited, or if you prefer using the basic functions of the valve without needing a control unit.

The valve enables watering based on precise time or flowed water volume. You can set cycles, for example, for even/odd days or at regular intervals, with up to six different schedules capable of being saved. Weather-based rules automatically skip watering  during unfavorable conditions (like rain), preventing both water waste and plant damage from overwatering.  

You can set a maximum watering time limit yourself. If the desired volume is not reached within this time (for example, due to low water pressure), the system automatically shuts off. This prevents a situation where a slow water flow would unnecessarily delay and disrupt the rest of your watering schedule.

Seasonal Adjustment

Adjust the duration and volume of watering according to the seasons using freely adjustable irrigation coefficients, ensuring plants receive adequate moisture all year round and eliminating unnecessary overwatering.

📝 Note: Before freezing temperatures arrive, turn off the water supply and drain any remaining water from the valve to prevent the device from freezing and cracking. The displayed irrigation coefficients are for reference only, and we recommend adjusting them according to local climate conditions and the specific needs of your plants.

Weather-Based Watering

In the event of bad weather, all watering cycles scheduled for the next 24 hours are automatically skipped, allowing the irrigation to better adapt to current weather conditions.

📝 Note: This feature uses weather data from external sources. Due to regional coverage and potential delays in data updates, actual weather conditions may vary, which can affect scheduled watering.

Advanced Protection

📱 Real-time Monitoring: The device sends instant notifications to the app if it detects:

🔋 Low battery

🚰 Water shortage

💧 Water leak

❄️ Frost

👶 Built-in child lock prevents accidental activation: When the child lock is activated, local buttons become inactive and control is only possible through the app

High-quality materials, easy installation 

The upgraded brass water inlet ensures superior corrosion resistance and higher strength. It is designed for reliable operation under long-term water pressure and direct sunlight, while the IP55 rating safely protects it from the outdoor environment. This product is recommended for users looking for a modern and easy-to-install irrigation control solution with the added benefit of water consumption monitoring.

📝 Note: Install the device vertically, as horizontal placement may reduce the accuracy of the water flow measurement.
