Alexa to play local mp3 file

Hi all,
I’m very new in HA. I would like to create automation scripts on HA and play mp3 file locally.
I tried app call “My Media for Alexa” it able to play via asking alexa to play mp3 file, but no luck on HA.
Anyone tried this?


It’s possible following this example. Your HA setup need to be accessible to the outside world for it to work. If not, you can try this setup.
