Grouping lights

ok, what is a better option for grouping lights?

using the light group functionality from home assistant (https://www.home-assistant.io/integrations/light.group/) or just the regular group option in the groups.yaml?

I like to group lights per room, but also nesting groups (floor --> rooms)

Definitely the light group. With the normal group you don’t get brigtness control for the group etc.

offcourse! thanks for your reply!

It does not seem like light groups are exposed to Google by Nabu Casa

Don’t know, I’m not using Google Assistant. However, I don’t see any reason why they could not be exposed. They have the same domain as a single light. I also don’t see any note about this not being possible in the documentation. How did you try to expose the light group and how did you create the light group?
