Node-Red TVHeadEnd EPG Dashboard

This flow provides two Node-RED dashboard tabs:

  • EPG Search:

    • Search the TVHeadEnd EPG by program channel (optional) and title (required)
    • Add a single recording
    • Add a series recording
    • Delete a single recording
  • Upcoming Recordings:

    • Search the list of upcoming recordings by channel and title (both optional)
    • Delete a single recording
    • Delete a series recording

Warning: TVHeadEnd provides a generic API endpoint for deleting entities by unique id. When a user clicks the Cancel or Cancel Serie button to delete the corresponding (auto-)recording, the unique id for the recording to be deleted is being sent from the browser to the Node-RED back-end. This potentially allows users to send malicious requests to delete any TVHeadEnd entity. For example, a malicious user could potentially delete entities like DVR Inputs, Channels, Recording Profiles, ... As such, the credentials used to connect to TVHeadEnd (see below) should only be given permissions to read the EPG, and create and delete (auto-)recordings.

To use this flow:

  • Install node-red-dashboard
  • Import flow into Node-RED
  • In the TVH Request sub-flow, update the TVH Request node to match your TVHeadEnd installation:
    • Update URL with the correct host, port, and sub-path as necessary. The URL must be a properly formatted URL that ends with {{{tvhPath}}}, for example http://tvh.lan:9981/{{{tvhPath}}}, http://192.168.1.1:9981/{{{tvhPath}}} or https://traefik.lan/tvh/{{{tvhPath}}}
    • Add the credentials for your TVHeadEnd installation
    • If necessary, enable Enable secure (SSL/TLS) connection
    • If necessary, enable Use proxy
  • In the TVH Record Action sub-flow, update the msg=[TVH Action] function node to specify the DVR profile UUID's for single and series recordings
  • Deploy flow
