Sonoff Hydro ONE Lite – Zigbee Irrigation Valve

Product detailed description

💦Sonoff Hydro ONE Lite - Smart Irrigation That Saves Your Time

The Hydro ONE Lite Zigbee water valve is a battery-powered smart irrigation valve designed for outdoor use. It allows you to perform scheduled and automated irrigation tasks in gardens, lawns, vegetable patches, or smaller irrigation zones. It is particularly useful for users who want consistent and predictable watering, or lack the time for daily irrigation chores. It is suitable for locations where programmability, weather adjustments, and remote control are important, but precise water consumption data is not required.

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

The valve allows irrigation based on precise timing. You can set cycles for even/odd days or at regular intervals, saving up to six different schedules. Weather-based rules automatically skip irrigation during adverse conditions (such as rain), preventing water waste and plant damage from overwatering. 

Seasonal Adjustment

Adjust irrigation duration according to the seasons using customizable watering coefficients, ensuring your plants receive appropriate watering year-round while eliminating unnecessary overwatering.

📝 Note: Before the onset of frost, close the water supply and drain all remaining water from the valve to prevent freezing and bursting of the device. The displayed irrigation coefficients are indicative only and we recommend adjusting them according to local climate conditions and the specific needs of your plants.

Weather-Based Irrigation

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

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

Advanced Protection

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

🔋 Low battery

❄️ Frost

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

Quality Material, Easy Installation

The upgraded brass water inlet ensures superior corrosion resistance and higher durability. It is designed for reliable operation under long-term water pressure and direct sunlight, while the IP55 rating safely protects it from outdoor elements. This product is recommended for users looking for a modern yet easy-to-install solution for irrigation management.

📝 Note: It is recommended to install the device vertically

Integration with Open-Source Platforms

Zigbee Ecosystem Compatibility 

Key Features

📶 Dual Connectivity: The device supports Zigbee 3.0 and Bluetooth Low Energy. Zigbee is used for remote access and system integration, while Bluetooth Proximity Mode is intended for nearby control and configuration.

📅 Six Irrigation Schedules: Up to six separate schedules can be created for selected weekdays, even or odd days, or repetition at specified day intervals.

🌦️ Weather-based Adjustment: In Zigbee mode, conditions can be configured based on rain probability, humidity, and temperature. When a condition is met, the system can skip irrigation programs scheduled within the next 24 hours.

🍂 Seasonal Adjustment: Irrigation duration can be modified for each month using a percentage multiplier without changing the base schedules.

🌧️ Manual Rain Delay: Upcoming scheduled irrigation programs can be suspended for a defined period with a single action.

💾 Local Schedules: Configured irrigation programs are stored in the device's internal memory. Once configured, they run at specified times even without an internet or Zigbee connection.

📊 Irrigation History: Irrigation duration can be viewed and downloaded in daily, monthly, and six-month summaries.

🔔 Safety Notifications: The eWeLink app can send notifications for low battery level and frost risk.

🔒 Child Lock: Disables the local control button while app-based control remains available.

🔧 Brass Connector: The threaded water inlet is made of durable brass.

🛡️ IP55 Protection Rating: Limited protection against dust and protection against water jets from any direction.

Protocols and Compatibility

📶 Zigbee 3.0: Low-power communication based on the IEEE 802.15.4 standard. A compatible Zigbee gateway is required for remote control, automation, and weather adjustments.

📲 Bluetooth Low Energy: Proximity mode creates a direct connection between the eWeLink app and the nearby valve.

📱 eWeLink: When used with a SONOFF Zigbee gateway, the app provides remote valve control, schedule management, weather-based adjustment, history, notifications, scenes, and device sharing.

🌐 Recommended SONOFF Gateways: ZBBridge-P, ZBBridge-U, NSPanel Pro, and iHost.

🔌 SONOFF USB Coordinators: ZBDongle-P, ZBDongle-E, ZBDongle-M, Dongle Plus MG24, and Dongle Lite MG21 can be used with compatible local Zigbee systems.

🏠 Home Assistant: Can be used via Zigbee2MQTT or ZHA integration. Available features depend on the current integration version and device handler.

⚙️ Zigbee2MQTT: Supports, among other features, valve status, battery data, child lock, manual watering duration, irrigation schedules, rain delay, seasonal adjustment, and irrigation history.

🔄 MQTT Integration: When using Zigbee2MQTT, valve status and settings can be managed via MQTT messages. The MQTT connection is provided by the Zigbee2MQTT system.

🛠️ ZHA: Can be connected to the ZHA network for Home Assistant. The manufacturer provides a dedicated ZHA script for Hydro ONE Lite for more comprehensive functionality.

🎙️ Amazon Alexa: Manual irrigation can be controlled via a compatible Zigbee hub. Detailed schedules, history, and battery info may not be available on every Alexa hub.

🌌 Samsung SmartThings: Aeotec Smart Home Hub V3 supports manual valve control and scene actions. Additional available features depend on SmartThings device support.

🏡 Google Home: Supported control functions are available by linking your eWeLink account.

🔗 IFTTT: Valve control and status can be used in automations via eWeLink integration.

❌ Unsupported Gateways: According to manufacturer documentation, the device is not compatible with Zigbee gateways from Philips or FRITZ!Box.
