I followed this integration → media_player.group
but I am unable to validate config with an exact copy of the the yaml in the documentation. My code write now is simply:
media_player:
- platform: group
entities:
- media_player.cuisine
- media_player.salon
When checking the config file I get:
Platform error media_player.group - No module named ‘homeassistant.components.group.media_player’
Is there something I’m supposed to activate before using the group platform?
