Use music Assistant remotly

Hi , I’m trying to listen to music via home Assistant when I’m not home . I have installed Zerotier for the remote access . The only problem is that music Assistant doesen’t see my iPhone as a media player . Someone has as idea of how I could do it ?

I dont think you can. Try using Navidrome or something else with subsonic and pick a player to your liking. There should be plenty available.
Then you can also connect music assistant to subsonic so you dont have file duplicates.
