For tetris you should also try this one: Falling Lightblocks (Not on F-droid, and you should import a theme)

• Audiobookshelf: Audiobooks
• Navidrome: Music
• Jellyfin: Movies, videos, audio and books
• Radicale: calendar, contacts and tasks
• Nextcloud: all files and more
• HomeAssistant: for managing the solar panels, battery and other iot

Thanks

If you have too many cardriges, and you decide to stop paying, you cannot print anymore.

I suggest an ink tank printer
