Unpackerr extracts downloads for Torrents, Radarr, Sonarr, Lidarr, Readarr, and deletes extracted files after import . Use it to automatically unpack archives after download.
Simply enable Unpackerr it in your account. You won't see it appear on your dashboard, since it's just a daemon running in the background.
You can examine the Unpackerr logs using File Browser, at /config/unpackerr/logs/. Log files are auto-rotated, so there's no need to worry about truncation, etc.
Unpackerr should "just work", provided you use both the built-in API keys for the Arr apps, and download to /media/downloads/completed. For more advanced Unpackerr options, you may (using File Browser edit /conf/unpackerr/unpackerr.conf and make further customizations.
