# Dynamic Media Library with On-demand Downloads for Radarr/Sonarr and Plex
|
||||
|
||||
---
|
||||
|
||||
### 1. Workflow Overview
|
||||
|
||||
This workflow, titled **"Dynamic Media Library with On-demand Downloads for Radarr/Sonarr and Plex"** (also called "n8n Placeholdarr for Plex"), automates the management of media libraries integrated with Radarr, Sonarr, and Plex. Its main purpose is to create **dummy placeholder media files** for movies and TV shows tagged as `dummy-unprocessed` in Radarr/Sonarr, allowing Plex to display these items without requiring the actual media files to be downloaded initially.
|
||||
|
||||
Key functionalities include:
|
||||
|
||||
- Detecting new or updated items in Radarr/Sonarr tagged for dummy file creation.
|
||||
- Creating dummy media files on the server filesystem using FFmpeg via SSH.
|
||||
- Monitoring playback via Tautulli and triggering real media downloads when dummy files are played.
|
||||
- Managing Plex collections populated from external sources (JustWatch and Trakt).
|
||||
- Automated refreshing of Plex libraries and *Arrs monitoring states.
|
||||
- Removing dummy tags and files when real content is available.
|
||||
- Handling user requests through Overseerr integration.
|
||||
- Managing collections dynamically, including adding/removing items based on external lists.
|
||||
|
||||
The workflow is logically divided into these blocks:
|
||||
|
||||
- **1.1 Webhook Input & External List Handling:** Receives webhooks from *Arrs apps, Tautulli, and external list triggers (JustWatch, Trakt).
|
||||
- **1.2 Dummy File Creation & Media Monitoring:** Creates dummy files and manages *Arrs monitoring states for movies and series.
|
||||
- **1.3 Plex Library and Collection Management:** Updates Plex collections based on external list data, including item lookup and collection refresh.
|
||||
- **1.4 Tautulli Playback Monitoring & Overseerr Requests:** Monitors playback of dummy files and triggers real downloads using Overseerr API.
|
||||
- **1.5 Utility and Cleanup:** Removes dummy tags/files after processing and handles session termination for dummy playback.
|
||||

||||
- Listens to POST requests on a specific path.
|
||||
- Outputs JSON body with eventType and media details.
|
||||
|
||||
- **Switch eventType (switch):**

### 4. Reproducing the Workflow from Scratch
|
||||
|
||||
1. **Create Webhook Nodes for Incoming Trigger Events:**
|
||||
- *Webhook Arrs Dummy file update*: POST method on path `/bd5102ad-9dc5-4415-b779-89d002c6e448`.
|
||||
- *Webhook Tautulli*: POST on `/9cc04992-377c-40fc-a0a9-810c08438224`.
|
||||
- *Webhook Arrs custom list JustWatch*: GET/POST on `/:filter/:limit/:objectType/:collectionId`.
|
||||
- *Webhook Arrs custom list Trakt*: GET/POST on `/:username/:list/:limit/:objectType/:collectionId`.
|
||||
|
||||
2. **Add Switch and If Nodes to Route Based on Event Type:**
|
||||
- *Switch eventType*: Route by `eventType` field (`Download`, `MovieAdded`, `SeriesAdd`).
|
||||
- *If Radarr*: Check if payload contains Radarr movie.
|
||||
- *If tag unmonitored exists* (Radarr and Sonarr branches): Check for `dummy-unprocessed` tag in media tags.
|
||||
|
||||
3. **HTTP Request Nodes for Radarr/Sonarr API Calls:**
|
||||
- Radarr: *Radarr movie*, *Get Radarr information from tmdbId*, *Monitor movie*, *Search movie*, *Remove unmonitored tag*.
|
||||
- Sonarr: *Sonarr series*, *Get Sonarr information from tvdbId*, *Monitor series*, *Monitor all seasons*, *Search season pack*, *Remove unmonitored tag Sonarr*.
|
||||
|
||||
4. **SSH Nodes for Dummy File Creation and Cleanup:**
|
||||
- Create dummy files with FFmpeg commands for movies and series.
|
||||
- Remove dummy files when needed.
|
||||
- Use SSH credentials pointing to media server with FFmpeg installed.
|
||||
|
||||
5. **Plex API Integration:**
|
||||
- Use HTTP Request nodes to refresh Plex libraries.
|
||||
- Manage Plex collections by fetching collections, listing items, adding/removing items.
|
||||
- Use Plex token with HTTP header authentication.
|
||||
|
||||
6. **External List Handling:**
|
||||
- Call JustWatch API with GraphQL POST requests.
|
||||
- Call Trakt API with appropriate headers and parameters.
|
||||
- Format results with Code nodes to extract TMDB, IMDB, and TVDB IDs.
|
||||
|
||||
7. **Collection Processing:**
|
||||
- Use Wait node to delay processing for 5 minutes after receiving list data.
|
||||
- Split collections and iterate with SplitInBatches and SplitOut nodes.
|
||||
- Add or remove items from Plex collections based on external list data.
|
||||
|
||||
8. **Tautulli Playback Monitoring:**
|
||||
- On playback start for dummy files, filter user from Overseerr users list.
|
||||
- Check if Overseerr request exists, create new request if not.
|
||||
- Terminate Tautulli dummy playback sessions after real media is available.
|
||||
|
||||
9. **Utility Nodes:**
|
||||
- Merge nodes to combine parallel branches.
|
||||
- Set and Code nodes to prepare data structures.
|
||||
- Respond to Webhook nodes for proper HTTP responses.
|
||||
|
||||
10. **Credential Setup:**
|
||||
- HTTP Header Auth credentials for Radarr, Sonarr, Plex, Overseerr API keys.
|
||||
- HTTP Query Auth for Tautulli API.
|
||||
- SSH credentials for media server with FFmpeg access.
|
||||
|
||||
11. **Parameters and Defaults:**
|
||||
- Configure URLs with local network IPs or hostnames.
|
||||
- Use proper paths for media folders (e.g., `/mnt/user/Media/Plex`).
|
||||
- Use correct Plex library section IDs for movies and series.
|
||||
- Set tags in *Arrs applications: `dummy`, `dummy-unprocessed`.
|
||||
- Disable "search on add" in *Arrs, set monitor to none by default.

### 5. General Notes & Resources
|
||||
|
||||
| Note Content | Context or Link |
|
||||
|--------------|-----------------|
|
||||
| **n8n Placeholdarr for Plex (BETA)** - This flow creates dummy files for Radarr/Sonarr items tagged `dummy-unprocessed`. When a dummy is played, the real media is requested and downloaded automatically. | Sticky Note1 in workflow |
|
||||
| Use the following webhook URLs format to integrate with *Arrs and external lists: | Sticky Note (12ccd64d-4ea8-4d65-9778-f067866b2c12) |
|
||||
| JustWatch Webhook format example and parameter explanations included. | Sticky Note (12ccd64d-4ea8-4d65-9778-f067866b2c12) |
|
||||
| Trakt.TV Webhook format example and parameter explanations included. | Sticky Note (12ccd64d-4ea8-4d65-9778-f067866b2c12) |
|
||||
| Requirements: SSH with FFmpeg installed, correctly configured API keys and tokens for Radarr, Sonarr, Plex, Overseerr, and Tautulli. | Sticky Note1 and Sticky Note6 |
|
||||
| Tautulli webhook instructions with sample payload for playback start events with dummy files. | Sticky Note3 |
|
||||
| To-do: Implement check to ensure no dummy files remain before removing tags. | Sticky Note2 |
|
||||
| If SSH cannot run FFmpeg, manually copy dummy files to dummy folder as fallback. | Sticky Note4 |
