I am trying to configure the "notify Card" To send a TTS to my sonos speaker but i keep getting an error that is putting me in a loop.
type: custom:notify-card
label: What would you like to say?
card_title: Broadcast
action: tts.speak
target: tts.piper
data:
message: $MSG
entity_id: media_player.great_room
Error: Failed to perform the action tts/speak. required key not provided @ data['media_player_entity_id']
Any suggestions?
