Easy to set up via Bluetooth with the Gardena APP With the GARDENA Bluetooth® Water Computer, you can easily configure your garden's automatic watering system on your smartphone or tablet.

The Gardena Water Control Bluetooth is weather resistant. Its design is simple yet elegant. The wireless watering computer is connected directly to the outside tap. Thanks to Bluetooth®, the water computer can be set within a radius of up to 10 meters, for example from the comfort of your garden chair.

A smartphone or tablet with Apple iOS or Android acts as a handy remote control. After installation, the GARDENA Bluetooth App® guides you step by step to connect the smartphone or tablet to the Water Control Bluetooth. You can then have the planning assistant suggest the ideal watering cycles for the plants or set up to three separate schedules as desired.

Each schedule consists of different start times and durations and can be repeated on different days of the week. A watering break can be set as needed to ensure the garden is not watered unnecessarily during a rainy week. This is good for the plants and saves water.

In combination with the optional GARDENA Soil Moisture Sensor, you can easily and automatically ensure that no water is given when the soil is already damp.

Three status LEDs on the control panel indicate the current status of the Bluetooth® connection, watering and of the 9 V alkaline battery used. The battery lasts a whole year.

If you want to water your plants outside of the watering cycle, you can manually start and stop watering at any time with the push of a button on the unit. Thanks to the GARDENA "Safe Stop" function, you always have automatic watering under control.

When the battery is low, the start of the next watering cycle is automatically prevented. This means you are always assured that the garden is protected against excessive watering at all times.
