Play unlimited amounts of personal music through Flow

Questions & Help
1

Hello everyone. I have my own media library with my audio tracks, and I would really like to play my tracks in Flow with lighting. My question is, how can I play an unlimited number of tracks? At the moment, I’m using WiiM Pro, but it has a limited number of presets (12). Spotify is also not suitable because it requires copyrights. Using Plex, my goal is achievable, but only if the storage is on the same local network as Homey Pro, which I don’t have the possibility for, because the Homey Pro devices are installed in different locations, and I can’t put a PC or NAS at each location. Thank you.
