Entity-button for groups

hey ! i’m using some entity-button in my lovelace and it’s working great ! except for group, let say i have a group like entity: group.all_lights_Kitchen and all the light in the group are on, the icon will not show me that the group is on…

is it something I need to do with the service data or something ?

I think you might have more luck with light groups instead of putting your light into a normal group.

still does the same thing …
