It looks to me like the main reason for moving to them to to be able to do things like colour / brightness across all the lights that support it. I don’t think that is possible with a normal group
Hmm I don’t think it’s good as the 'standard ’ groups of lights. Instead of creating a group containing the lights, and a toggle switch at the top for the group, the ‘group’ switch appears in the list of lights…
And it seems bugged as instead of the group card being called the name of the group, it just says ‘Light’
