This blueprint will help you automate an Alexa device connected to an amplifier that’s not always on.
It will:

  • turn on the amplifier and switch to the correct source when the Alexa device starts playing music
  • turn off the amplifier after 10 seconds of no music playing
  • stop playback on the alexa device if the amplifier is turned off or the source is switched

It is intended for the following setup:

  • One “Main” Alexa device which you’ll talk to and get answers from
  • One “Music” Alexa device which will be muted
  • An amplifier which is controllable in Home Assistant via a media_player entity

The “Music Alexa” must be connected to the amplifier.
Set up a group in the Alexa app and add the “Main” and “Music” Alexa and set the preferred speaker for music to the “Music Alexa”.

:zap: This blueprint currently doesn’t support multiroom audio groups. The amp will not turn on if you, for example, start music on the “Everywhere” group. This feature might get added in a future version of this blueprint.

This blueprint requires the alexa_media custom integration.
