Claber Hydro-4 BT & Rain Sensor Bundle
The Claber 90840 Hydro 4 BT is the next-generation evolution of Claber's popular all-in-one irrigation system. This updated version integrates Bluetooth technology, allowing you to manage your entire garden’s watering schedule directly from your smartphone via the myClaber app (for iOS and Android). It can also be paired with the Claber 90844 Bluetooth rain sensor (sold separately).
The Hydro-4 BT is a professional-grade, all-in-one irrigation solution that manages up to 4 independent watering lines. This pre-assembled unit combines a battery-powered timer and four solenoid valves inside a rugged, compact valve box, making it ideal for gardens up to 700 square meters.
Because it is battery-operated (batteries not included), the Hydro-4 requires no electrical wiring, allowing quick installation above ground or buried underground. It features an IP68 waterproof rating, providing the highest level of protection against water, dust, and moisture.
Rain Sensor
Easily programmed from your smartphone via Bluetooth® with the intuitive myClaber app (iOS and Android). The Claber 90844 Rain Sensor automatically pauses the next water timer irrigation cycle when rainfall is detected (at 5 mm/m²) and resumes at the next scheduled cycle once the rain stops. Bluetooth-enabled, it is compatible with all products in the Claber myAquaSystem range. Designed for outdoor installation in rain-exposed areas, it mounts easily using the supplied bracket. No electrical connections are required. Powered by two 1.5 V AA alkaline batteries (not included).
