Shinobi would absolutely do that if that’s all you want it to do. It’s definitely not a one-click setup either, though, unfortunately.

Personal preference: Jellyfin instead of plex

Some that I run that you don’t seem to have anything for:

• Lancache (if you have several gaming PCs on the network or host any kind of lan party)
• surveillance camera software e.g. shinobi
• I see grafana, but other monitoring services like icinga, librenms, etc
• Mayan EDMS - I’ve found this really helpful as anything I get in the mail, I scan in, and this makes it all searchable and retrievable.
• There’s a whole hole you could dig if you start getting into home automation (I use home assistant)
