Unfortunately, Radarr and Sonarr run on a Digital Ocean droplet, but the PMS runs on a RPi 4 at home. You see I have bad peering and there’s also the issue of CGNAT
Script to assist sonarr/radarr with plex imports. Will only scan the folder that has been imported, instead of the whole library section. - l3uddz/plex_autoscan
Plex Autoscan is a python script that assists in the importing of Sonarr, Radarr, and Lidarr downloads into Plex Media Server.
It does this by creating a web server to accept webhook requests from these apps, and in turn, sends a scan request to Plex. Plex will then only scan the parent folder (i.e. season folder for TV shows, movie folder for movies, and album folders for music) of the media file (versus scanning the entire library folder).
In addition to the above, Plex Autoscan can also monitor Google Drive for updates. When a new file is detected, it is checked against the Plex database and if this file is missing, a new scan request is sent to Plex
So you can either have Sonarr/Radarr send the notice or just have PAS monitor GDrive
