The ETS Inside server should be physically connected to the installation. To define the way it is connected (interface between ETS Inside server and the KNX installation), you have to go on the dashboard of your ETS Inside and tap the "Connections" button on the main toolbar.
As soon as you tap the 'Connections' button, you will be redirected to the Connections page. If there are any KNX interfaces found, then they will be displayed in the list.
On the right side, you can see the discovered bus connections. To select one, just tap on it.
As soon as you tap on it, the connection becomes active, it is shown under the "Current connection" window on the left side and disappears from the 'Discovered' connections on the right side. Consequently, you can now proceed with the configuration of your project with ETS Inside.
NOTE: USB and IP routing interfaces are automatically recognized and displayed in ETS Inside and they do not need to be created. An interface that has not been automatically recognized cannot be used.
