Hi Can I choose room in configuration.yaml? Example light group or platform switch light?
light: - platform: group name: Lights muuri entities: - light.muuri1 - light.muuri2 - light.muuri3 - light.muuri4 - platform: switch name: Khh light entity_id: switch.plug_khh_valo
Rooms are “Area” in HA, and you can only do that via the UI as described here How to define AREA in "configuration.yaml"?
The post you mentioned is 2 years old. And that time I was told that areas are still in progress. Now, after 2 years, it is expected that areas may be selected in yaml too - unless devs decide to move settings to UI only.
