lights of a group

It’s not a Group, it’s a Light Group. They’re two different integrations.

You can expand a Group directly but for a Light Group you must do what Central Command provided (expand the Light Group’s entity_id attribute).

Another example of expanding a Light Group can be found here:

Light group for lights that are already on

If you already have a Light Group (defined with a fixed list of light entities), a template can use it to determine which of its members is currently on or off. For example, if your Light Group is called light.first_floor then this template will select all members that are off and present them as a comma-delimited string of entity_ids. {{ expand(state_attr('light.first_floor', 'entity_id')) | selectattr('state','eq','off') | map(attribute='entity_id') | join(',') }}
