Download backup via Shortcuts app

[flochtililoch]

I'm looking for a simple way to transfer my backups from my HA instance, to an iCloud directory.

Ideally, we would want two new actions to the Shortcuts actions exposed by the HA iOS app:

• List backups: no entry param,
  return a list of files
• Delete backup: File as entry param, return boolean

These could then easily be chained in an automated Shortcut to move the files.

My current approach is running Samba as Home Assistant Add-on, connect to the backup share in the Files app, then moving files over. A wrote a shortcut for this but it never worked well because authentication won't work when device is locked, and recent iOS broke the integration with remote drives in Files app anyway.

I can do iOS dev and would love pointers to help build this.

Hopefully this seems useful to others too!
