Remote control via Zigbee
Hydro ONE Lite uses the Zigbee 3.0 standard. After connecting to a compatible Zigbee gateway, the device can be operated remotely in the eWeLink app and used in Smart Home scenes and automations.
Examples of compatible gateways: SONOFF ZBBridge-P, ZBBridge-U, NSPanel Pro, and iHost. The device can also work with selected Zigbee coordinators and third-party platforms, although the range of available functions depends on the system used.
Local control via Bluetooth
SONOFF Hydro ONE Lite also allows for a direct connection to a phone via Bluetooth. The local mode allows you to use basic functions, including setting schedules, without using a Zigbee gateway.
Connecting to a Zigbee gateway provides a wider range of functions, such as remote access, automation scenes, and app notifications.

Precise irrigation schedules
The valve allows you to create up to 6 irrigation schedules. You can specify the operating time and select days of the week, even or odd days, so that watering can be tailored to a specific garden and irrigation method.
The seasonal adjustment function allows you to change the intensity of scheduled watering without the need to manually edit each schedule. Watering delay functions and automations taking weather conditions into account are also available.
Irrigation history
Hydro ONE Lite saves the valve's operating history, allowing you to check irrigation time on a daily, monthly, or half-yearly basis. The data can facilitate schedule control and assessment of how the installation is used.

Alerts and security
The device monitors basic operating conditions and can inform the user about events requiring attention. Hydro ONE Lite also has a child lock, which, when activated, disables local button control and leaves the possibility of operation from the app level.
- Low battery notification.
- Warning about the risk of freezing at low temperatures.
- Local device button lock.
- Possibility of temporary delay of scheduled irrigation.
Compatibility with Smart Home automation
The Zigbee 3.0 standard allows for the integration of the valve with compatible automation systems. Hydro ONE Lite can work with eWeLink, Home Assistant, Alexa, and SmartThings, among others, although the availability of individual functions depends on the gateway or coordinator used.
Integration with Apple Home is possible via a compatible Matter bridge, for example, a solution based on SONOFF ZBBridge-U or eWeLink CUBE. In the case of Home Assistant, solutions using Zigbee2MQTT and ZHA are supported, however, the range of available functions may differ depending on the configuration.
