The groov View server is not part of RIO, there just was not the need since it has a limited I/O count.
The only only GUI that you can get working on RIO are the Dashboard Nodes.
But even then, you wont be able to use the groov View app on your phone to connect to those nodes either since the app has been built just for groov View… Just use your phones web browser to view the mini web server that the dashboard nodes create.
