Room Card

[joe-winter]

Is it possible to have the template that controls the colour of the room card apply based on a conditon. For example if presence is detected, the room card becomes green.

[guger]

You can set the entity_id to that of the presence detector and add a color template, blue_on, for example, to the template configuration of the card.
