@Lepracon68 that would be nice!

Thanks to you and Michael Teeuw the MM is the best project for RPI I have ever seen.
I appreciate your interest and help.
I just succeeded in adding a MMM (Earth)( happy me!).
Things that do not work up till now: MM does not start automatically and I still have to find out how to combine two Calendars.

Mykle1, your project is an inspiration for this other old man (62) in the Netherlands.
The RPI is running, old monitor is found, so I can start the project!
It will take a lot of reading and searching!
