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.
> Keep an eye on the GitHub repository for updates.
