Okay , I found a work around.
- Open Home Assistant Media browser.
- Choose Player → Select Web Browser.
- Opened Dev Console on the browser, go to Network tab.
- Select the media you want to play. Once it starts playing Check the Network tab. Copy the request URL and use it as the “media_content_id”
This is how mine looks.
service: media_player.play_media
data:
media_content_id: http://10.10.10.190:8123/media/local/private/WhiteNoise.mp4?authSig=eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpc3MiOiJjNTMxNDE2Y2IxYmE0M2ViYmE4N2YxNDAxZmY0ZTY0MCIsInBhdGgiOiIvbWVkaWEvbG9jYWwvcHJpdmF0ZS9XaGl0ZU5vaXNlLm1wNCIsImlhdCI6MTYyODYzMTEyNSwiZXhwIjoxNjI4NzE3NTI1fQ5SYn1_FC4BZzZtvyWPlG0Kx_QxNe4
media_content_type: music
entity_id: media_player.googlehome7641
EDIT ------ The copied Authkey expires.
I found a NodeRed solution to request authkey everytime.
