Looking for firestick automation as an alarm clock

I would like to create an alarm clock automation. The lights should gradually come on and at some point television channels or music from the FireStick should be played on the television.
My problem is that I can get the stick integrated via ADB and can also control it manually from HA, but unfortunately I can’t automate it.
Every now and then it works to get the stick and TV out of standby with the media player start command, but not always and I can’t get anything to start up. Can anybody help me further? Does anyone already have this in use?
Thank you in advance for all the tips and advice.
Best regards
