I have a Grandview motorised projector screen and a BroadLink RM4C mini, but I don’t have the original remote.

If you are in this position, then the following may be useful:

File: /config/.storage/broadlink_remote_<INSERT MAC ADDRESS>_codes

{
  "version": 1,
  "minor_version": 1,
  "key": "broadlink_remote_<INSERT MAC ADDRESS>_codes",
  "data": {
    "Grandview" : {
      "Up" : "JgBCACoLKgsqCyoLDiYOJg4mDiYOJg4mDiYqCw4mDiYOJioLKgsqCw4mKgsqCyoLDiYqCyoLKgsOJioLKgsqCyoLDgACzQ0FAAAAAA==",
      "Down" : "JgBCACkMKQwpDCkMDiYOJg4mDiYOJikMDiYOJg4mDiYOJikMKQwpDCkMDiYpDCkMKQwOJg4mDiYOJikMKQwpDCkMKQACrg0FAAAAAA==",
      "Stop" : "JgBCACoMKgwqDCoMDiYOJg4mDiYOJg4mKgwOJg4mDiYOJioMKgwqDA4mDiYqDCoMDiYOJioMKgwOJioMKgwqDA4mKgACsg0FAAAAAA=="
    }
  }
}

Then I created a template cover in configuration.yaml:

cover:
  - platform: template
    covers:
      lounge_projector_screen:
        device_class: blind
        unique_id: "GrandView_cover"
        friendly_name: "Lounge Projector Screen"
        close_cover:
          - service: remote.send_command
            target:
              entity_id: remote.wi_fi_universal_remote_remote
            data:
              device: Grandview
              command: Down
        open_cover:
          - service: remote.send_command
            target:
              entity_id: remote.wi_fi_universal_remote_remote
            data:
              device: Grandview
              command: Up
        stop_cover:
          service: remote.send_command
          target:
            entity_id: remote.wi_fi_universal_remote_remote
          data:
            device: Grandview
            command: Stop
        icon_template: mdi:projector-screen

This works and I can now automate raising and lowering the screen.

If you are starting from scratch, you should

  • create the initial broadlink codes file (by recording any button off any remote),
  • use Visual Studio code or similar to find and edit the file created
  • then you can just insert the “Grandview” dictionary item with the codes.

For historical reference, these are the full codes:
