Dynamic Media Library with On-demand Downloads for Radarr/Sonarr and Plex

n8n Placeholdarr for Plex (BETA)

This flow creates dummy files for every item added in your *Arrs (Radarr/Sonarr) with the tag unprocessed-dummy.

It’s useful for maintaining a large Plex library without needing the actual movies or shows to be present on your Debrid provider.

How It Works

• When a dummy file is played, the corresponding item is automatically *monitored in Arr and added to the download queue.
• This ensures that the content becomes available within ~3 minutes for playback.
• If the content finishes downloading while the dummy is still being played, Tautulli triggers a webhook that stops the stream and notifies the user.

Requirements

• Each n8n node must have the correct URL and authorization headers configured.
• The SSH host (used to create dummy files) must have FFmpeg installed.
• A Trakt.TV API key is required if you're using Trakt collections.

Warning

⚠️ This flow is currently in BETA and under active development.
It is not recommended for users without technical experience.
