Hi Peter,
I have never used Astroberry but am using the very similar KStars/Ekos/indi on a Rpi4. It works really nicely and controls all my equipment from inside in the warm (using NoMacine to control the Pi headless). Just wish that it would set my equipment up for me too!
If you have not looked yet there is lots of info on Astroberry on the Indilib site as it all runs though indi drivers etc.
Here is the link (KStars and Ekos info on there too).

Go to category - Astroberry and have a look through the forum and see what others are doing with it.
