What issues are you having with the aeon doorbell? I’ve been using mine for all my mp3 notifications and it works great.

So does anyone know of a SIMPLE approach to get TTS or MP3 notifications working with a BT Speaker, Echo, or Doorbell?[/quote]
In SHM, all you have to do with the doorbell is select the it as an audio device, choose Custom Message and specify the track number.
In Core you can use the play track command to play a specific track number.
The other responses are probably better, but I just wanted to point out that the Aeon Labs Aeotec Doorbell should be a relatively simple solution to play mp3 notifications.
