I don’t see the master attribute anymore for my Sonos and whilst I can successfully join a group of speakers I can find no way to adjust the volume of the group as a whole.
Can this still be done?
This will join them…
sonos_group_some_speakers: alias: Sonos Some Speakers sequence: - service: sonos.join data: master: media_player.speaker1 entity_id: - media_player.speaker1 - media_player.speaker2
…but this only changes the volume of speaker1 (which is set as the master)
- service: media_player.volume_set data_template: entity_id: media_player.speaker1 volume_level: 0.5
