ive been using kodi (xbmc was better moniker) since google killed sagetv. i recall attempting plex, but it seemed to lack some open/extensibility (its been awhile).
i have a side project i want to make as a modular plugin generating a cable layout with original air orders and networks/channels... kodi seems most optimal, but ill admit its been a long while since i looked at plex.
Have you tried to install add-on or scraper to Kodi? On mobile or remote bases device. Please let me know how many steps it take to that, and also when you find a scraper , how long it actually stays up
Kodi is extremely fussy about file names for automatic scraping. If you follow the naming standards, which is easy if you using something like sonarr, the built in scanner will work fine.
