Component/platform: light groups doc
Description of problem: impossible to differentiate between actual lights, and light groups.
Relevant configuration.yaml entries:
- platform: group
name: rooma
entities:
- light.bulb1
- light.bulb2
Description: There are scenarios (like this) where it would be helpful to be able to differentiate between actual lights (light.bulb1 and light.bulb2 in the configuration above) and a light group (eg. light.rooma).
Suggestion: This could be done by automatically adding an attribute to light groups; for instance is_group = true, similar to the attribute is_hue_group: true which is set for light groups imported through hue.
