# Grainfather This functionallity is still in beta, use the integration at your own risk and provide feedback on your experience. Only tested with G30. This integration is only supported using a chromium based browser (like Chrome or the new Edge), on a device with bluetooth. It also works using the web version of the app on an android device in the chrome browser. iOS or other browsers are not supported at this time. Enabling the GF Bluetooth Control toggle in the settings page enables you to send your recipe directly to the GF Controller. Go to the brewing tab of a batch, then you can click start in the brew-controller section of the batch to connect to your controller. Depending on the chromium browser and your operating system you might have to enable browser bluetooth support to make the bluetooth connect dialog show: Enter **chrome://flags** in the searchbar.
