I just published an Empeg remote for Android called Empeg Remote
At the 2019 Meet near Cambridge, several attendees had not heard of this app. I still use it myself, and strongly recommend it to others.
But it is no longer listed on Google Play. So I have PM'd the author (suomi35
) to see what the current status is. Ideally we might work out a scheme for me to just provide it inside the new all-in-one builder_v21 images. We'll see.
