I just added the 7" display and reinstalled RoPieee to enable it. Sound works fine and in general the Screen UI is super, but ever so often it shows a “Connection Failure” screen before it resumes normal function. This happens multiple times per minute. Looking at it from Roon extension config page it shows the extension goes from status running to disappearing altogether and then returning to running when RoPieee goes back to normal. The music plays uninterrupted while this happens.
Only wired Ethernet for the involved parts (Library, Core, RoPieee) and since the music is playing I assume I got the zone name right in the RoPieee config, right?
Only thing I can think of is that the under-voltage icon was popping up every now and then during boot. (Power supply is specified as 5V 3,1A so I thought it would be enough to power a Pi 3B plus the 7" touch screen…)
I sent feedback e671c8a2df253602 for your troubleshooting.
Thanks for your advice
