Claber Hydro-4 Programmable Bluetooth Valve Boxes

4-valve irrigation controller | App programmable via Bluetooth® | IP68 fully waterproof

The Claber Hydro-4 Bluetooth® Valve Box is a compact, ready-to-use solution for managing irrigation in residential gardens. This watertight valve box houses a battery-powered controller and four solenoid valves, offering full control of underground or drip irrigation systems via the myClaber app (iOS and Android) using Bluetooth® technology.

Designed for flexibility, the Hydro-4 can be buried or installed above ground with minimal effort. Each outlet is programmable with up to 2 independent programmes and a maximum of 8 watering cycles per day. Watering durations can be set from 1 minute to 2 hours, and weekly scheduling allows the exclusion of individual days. The manual function (default 15 minutes, adjustable up to 120 minutes) enables immediate activation of watering or preset programmes. The integrated Water Budget feature allows seasonal adjustment between 50% and 150% without changing programmed schedules.

Durable and reliable, the Hydro-4 features a fully sealed IP68 housing, protecting against water, dust, and moisture. Operates with 2 x AAA 1.5V alkaline batteries (not included), and can connect to the Claber Rain Sensor BT (CTS9260) for automatic rainfall override.
