Keep your garden green with the Hombli Smart Controller. You can precisely set which days, how long, and how often your garden should be watered. This prevents your plants from receiving too much water, and you no longer have to worry about turning off the sprinkler. The irrigation system consists of two parts: a controller and a gateway, which you can easily control with your smartphone or tablet to automatically water your garden. The controller delivers the right amount of water. The included gateway connects the sprinkler to your smartphone.
