The Gardena 9 V Bluetooth control unit is designed to control the Gardena 9 V irrigation valve and can be easily programmed from a distance of up to 10 meters from the device via the Gardena Bluetooth app on a smartphone or tablet. It allows for six different irrigation plans, where time, duration, and days of the week can be set. Status LEDs provide information about the Bluetooth connection, battery status, and irrigation. The "Water Now" function allows for immediate irrigation without changing the settings. It is suitable for retrofitting Gardena 9 V irrigation valves and replaces the 9 V control unit and programming unit. The control unit can also be used with the Gardena soil moisture sensor.
