Fetching Plex library info via Rest

Configuration
1

I’m trying to monitor my Plex server with some rest sensors. I created a new sensor which connects but I get the attributes back prefixed with @ and can’t seem to get the one value I want into the state attribute. Can anyone advise where I am going wrong/what to try?

- platform: rest

  name: Plex Unmatched Episodes

  resource: http://192.168.0.100:32400/library/collections/14152

  headers:

    User-Agent: Home Assistant

    Content-Type: 'application/json; charset=utf-8'

  params:

    X-Plex-Token: !secret plex_token

  scan_interval: 600

  json_attributes_path: '$.MediaContainer.Directory'

  json_attributes:

    - "@childCount"

    - "@title"

    - "@updatedAt"

  value_template: '{{ value_json["MediaContainer"]["Metadata"][0]["childCount"] }}'

The JSON response is like this:

{
  "MediaContainer": {
    "size": 1,
    "allowSync": true,
    "identifier": "com.plexapp.plugins.library",
    "librarySectionID": 1,

      }
    ]
  }
}

Aren’t you reinventing the wheel?

No, already have that set up but you don’t get access to the Library collections, only top line stats about a library. I’m looking to monitor for when files have not added to Plex and need manual intervention.

Solved. Plex needs accept rather than content type to fetch as Json.
