I will use ropieee to create a roon bridge on a Pi 3b+ Then I will connect the meridian explorer 2 to the USB as audio output and…
I would like to use an old tablet android as screen to see what is playing
Is this possible (if yes how) or am I aiming at the sky?
The first part for sure. That’s the whole idea with RoPieee
About the tablet… that depends on what you exactly mean. For sure you can run the Roon application on your tablet and indeed see what’s playing. It’s not a dedicated screen however.
