Anybody have success sending to a group of echoes rather than a single echo?

@dmayo305, Just use a dash with each echo in your YAML:

service: notify.alexa_media
data:
  message: >-
    <audio
    src='https://myPublicURL.ui.nabu.casa/local/mp3/doorbell-chime.mp3'/>
  target:
    - media_player.colton_s_echo_show
    - media_player.apartment_door_echo_amz
    - media_player.bedroom_echo_right_amz
    - media_player.kitchen_echo_plus_amz
    - media_player.bathroom_echo_amz
    - media_player.bedroom_echo_right_amz
  data:
    type: tts
enabled: true

I had the same problem with "Simon says ...". Finally, I could fix it by correcting the source-statement of the mp3-file.
It seems that the source needs to be like this (watch the different quotation marks):

src='https://abcdef.ui.nabu.casa/local/mp3/Alarm.mp3'/>
