It’s subscription only for now. A one time payment to go and free will be added.

Port 443 through Traefik and a port for Plex.

I name devices after Greek Gods / Goddesses. My main server is called Olympus.

I found the DietPi OS to be great for getting a media server going. Alternatively, just install a lightweight OS, install docker, then set up Sonarr / Radarr / Prowlar / Overseerr (or Jellyseerr) / a torrent client / Jellyfin using docker. Make sure you transfer the OS off the memory card though, they eventually corrupt if you run the OS off them. Not sure about a remote, Plex let’s you use the android app to fling media to another Plex app on the same network, maybe Jellyfin has similar?

Drunkenslug and NZBGeek seem to be the go to for Indexers. I use Sunny Usenet as a provider.
