Custom Sounds in iHost

i have been using the TTS which is working great, i have the iHost connected to a bluetooth speaker in my house and i want to have it say “You Got Mail” but the way AOL used to when the door opens on the mailbox. i have a WAV file here on my computer what i would like to have ihost play. does anyone know how i can get it there or if i can replace the WAV file generated by TTS docker app with the one on my local computer?

I think they haven’t opened up the storage access

Can you try this add-on;

Yes! You are the man! It uses the same port as mqtt2cube but this is exactly what I was looking for!

Suspect you can bodge your own version using the EWeLink Cube Open API V2 if you want that port still available.
