Control your garden irrigation conveniently via the free Gardena Bluetooth® App Wireless connection with a range of up to 10 metres Create up to 3 individual and automated watering schedules ‘Safe Stop’ function prevents watering when battery power is low Manual watering is possible at any time with a simple button press Weatherproof, elegant design installs directly onto your outdoor tap Smart, App-Based Garden Watering The Gardena Water Control Bluetooth® provides a modern, convenient solution for automating your garden’s irrigation system. This weatherproof and elegantly designed device attaches directly to an outdoor water tap, allowing you to configure and manage watering schedules from the comfort of your garden lounger using a smartphone or tablet. With a Bluetooth® range of up to 10 metres, manual adjustments at the tap are a thing of the past. Intuitive Setup and Scheduling Getting started is simple. The free Gardena Bluetooth® App (for iOS and Android) guides you step-by-step through the connection process. Once paired, you can use the Scheduling Assistant to suggest ideal watering cycles for your plants or create up to three distinct, individual schedules. Each schedule can have different start times, durations, and repeat on specific days of the week, offering complete flexibility for any garden layout. Water-Saving Features and Manual Control The system is designed to be efficient. A ‘rain break’ function can be activated to pause watering during wet weather, saving water and protecting plants from over-saturation. For even greater efficiency, it can be connected to the Gardena Soil Moisture Sensor (sold separately), which ensures watering only occurs when the soil is dry. For immediate watering needs, a central button on the unit allows you to start and stop a watering cycle manually at any time. Reliable and Safe Operation Engineered in Germany for durability, the Water Control Bluetooth® features three status LEDs to show the current Bluetooth® connection, watering status, and battery level. The required 9V alkaline battery (not included) provides power for a full year of operation. Gardena’s ‘Safe Stop’ technology adds peace of mind; if the battery power is too low to complete a full cycle, the system will not start, preventing your garden from being overwatered or the system being left open. This ensures you always have your automatic watering under control.

Frequently Asked Questions Frequently Asked Questions How do I control the Gardena Water Control? The device is controlled wirelessly using the free Gardena Bluetooth® App on a compatible smartphone or tablet (iOS or Android). You can program schedules, start manual watering, and check the status from up to 10 metres away. What kind of battery does the Gardena 1889-28 need? It requires a single 9V alkaline battery, which is not included with the product. A fresh battery should provide enough power for approximately one full year of operation. Can I use this water timer if rain is forecast? Yes. The app allows you to set a ‘rain break’ to pause your automated schedules, preventing unnecessary watering and saving water. For fully automated rain detection, it can be paired with the Gardena Soil Moisture Sensor (sold separately). What happens if the battery runs out during a watering cycle? The Gardena ‘Safe Stop’ function prevents this from happening. If the system detects that the battery level is too low to complete a scheduled cycle and safely close the valve, it will not start the cycle at all. This protects your garden from being overwatered.
