Change group of lights brightness/temperature without changing state

Configuration
1

Hi,

I’ve a group of two lights. Sometimes both are on, sometimes only one of those. If I use the “turn_on” service on the group, and only one light is on, both turn on.

Sometimes I’d like to change the brightness or the color of light (lights) that are currently turned on. I can go to each light separately and change its parameters, but I’d like to use the group for that.

Is it possible?

Yes it’s possible, check out the action section in: Automate multiple lights, but only the ones that are on - #7 by Didgeridrew

That is not exactly what I wanted, but thanks anyway, now I know where to look for the solution.
