Integrate a Siri Remote

Hello,

Migrating from a Mac based home automation to HAOS on a Pi5.
I was aware of the existance off Home Assistent but never really tried it.
Must say I’m blown away by the possibilities. Wrote my first integration within a month.

Only 1 thing left to migratie and that is the use of a Siri Remote. Goal is to only use the Pi5.

Currently the Siri Remote is paired to a MacMini and using the app BetterTouchTools on this Mac I can use a POST command to an endpoint in AppDaemon to expose the buttons pressed.

What I would like to do is that HA reads the buttons pressed via BT directly.

Not really finding the right way to do this.
Any ideas are welkom.

Found this but not sure it will work with HAOS:

Greetings,
Adrian
