I put together Sonarr and Radarr Activity Modules to show recent downloads, so it was pretty easy to copy the Sonarr one and have it look at the calendar endpoint instead of the activity endpoint. Enjoy!

This is a module for MagicMirror, intended to show the latest downloaded episodes from Radarr.
Easy enough to modify my first one to access Radarr, enjoy:
Just put together my first module to get the lay of the land. This will show the latest downloads from your Sonarr installation. Next up, a ZoneMinder module!
