Broadcasting to Alexa audio group from Spotify in HA

Hello,

I’m very new to the Home Assistant world and just trying to get things setup. I am trying to find a way to play music on a specific Spotify/Alexa audio group called everywhere. I have connected Spotify to HA and tried using scenes but don’t get much luck as it just seems too play music on the last selected source, even when I select the source within the scene. If for instance Spotify then started playing on my bedroom group when I triggered the scene it will just play on the bedroom group rather that switching to the everywhere group. I have also looked at automations but not sure how I would trigger the everywhere group. This is the current YAML code for the automation:

description: “”
mode: single
trigger:
condition:
action:

Is there a code I can use to specify the source/audio group or does anyone know of a simple way to do this in HA?

Many thanks for your help in advance,
Mark
