Core service routing#

core_service is the flag DUMB uses to route automation between Arrs and the core download workflows. It keeps Debrid- and Usenet-based stacks isolated while still allowing multiple instances of the same Arr service.

Where `core_service` is used#

Config block	Purpose
Arr instances (`sonarr`, `radarr`, `lidarr`, `whisparr`)	Selects the download workflow(s) to auto-wire.
NeutArr instances	Filters which Arr instances are sent to NeutArr.
Profilarr instances	Filters which Arr instances are auto-linked to Profilarr.
rclone/zurg instances	Labels the instance for the workflow it supports.

Supported values#

Use one or more of the core workflow keys:

Value	Workflow	Typical use
`decypharr`	Debrid and/or Usenet workflow	Decypharr torrent and Sabnzbd-compatible Arr clients
`nzbdav`	Usenet workflow	NzbDAV + Usenet indexers
`altmount`	Usenet workflow	AltMount SABnzbd-compatible client + Usenet indexers

Leave core_service empty if you do not want DUMB to auto-wire a service into a workflow. To combine workflows, set core_service to a list or use a comma-separated string.

What DUMB does with it#

When core_service is set on an Arr instance, DUMB:

Configures matching download clients (Decypharr, NzbDAV, and/or AltMount).
Adds or updates Arr root folders and permissions for each workflow.
Creates Prowlarr apps tagged with the same core service(s) so indexers sync only to the intended Arrs.

When core_service includes multiple workflow keys, DUMB uses a shared root folder base at /mnt/debrid/combined_symlinks/<slug> for the Arr instance.

When core_service is set on a NeutArr instance, DUMB:

Sends Arr instances whose core services overlap the NeutArr instance.

When core_service is set on a Profilarr instance, DUMB:

Auto-links only Arr instances whose core services overlap the Profilarr instance.
Seeds profile/custom format/regex/media-management sync for those Arr instances (when use_profilarr is enabled on the Arr).

Example: split Debrid and Usenet workflows#

"radarr": {
  "instances": {
    "Debrid": {
      "enabled": true,
      "core_service": "decypharr",
      "use_neutarr": true,
      "use_profilarr": true,
      "port": 7878
    },
    "Usenet": {
      "enabled": true,
      "core_service": "nzbdav",
      "use_neutarr": false,
      "use_profilarr": false,
      "port": 7879
    }
  }
}

In this layout:

The Debrid Radarr instance syncs with Decypharr and Debrid indexers.
The Usenet Radarr instance can sync with Decypharr, NzbDAV, AltMount, or any selected Usenet workflow service.
NeutArr only receives the Debrid instance because use_neutarr is set there.
Profilarr only links the Debrid instance because use_profilarr is set there.

Example: combine workflows on one Arr instance#

"sonarr": {
  "instances": {
    "Combined": {
      "core_service": ["decypharr", "nzbdav", "altmount"],
      "use_neutarr": true,
      "use_profilarr": true
    }
  }
}

In this layout, DUMB wires Decypharr, NzbDAV, and AltMount download clients and root folders for the same Sonarr instance.
