Hi all, I have a strange issue with what should be a simple thing: changing volume level of a media player.
When I test the service in the “Developer tools”, it works perfectly: calling the service increases volume level.
service: media_player.volume_up
target:
entity_id: media_player.rez_de_chaussee
But, when I try to use this service as a tap_action for a button, I get an error message: "service must contain at least one of entity_id, device_id, area_id
tap_action:
action: call-service
service: media_player.volume_down
target:
- entity_id: media_player.rez_de_chaussee
What am I doing wrong?
