SONOFF Hydro ONE Lite – Zigbee Smart Watering Controller
The SONOFF Hydro ONE Lite is a smart irrigation controller designed to simplify and optimize garden watering. Replacing traditional button-based programming with a mobile visual interface, it allows convenient management of irrigation schedules from anywhere.
Supporting both Zigbee 3.0 and Bluetooth Low Energy connectivity, the controller can integrate into smart home ecosystems through a Zigbee gateway or operate locally in Proximity Mode when no gateway is available.
Its durable brass water inlet and IP55-rated housing are designed for outdoor use, while advanced scheduling, seasonal adjustments, and weather-based automation help reduce water waste and maintain healthier plants throughout the year.
