Relative Brightness Light Group

Thanks a lot for this functionality, it works well and I feel like this should be part of home assistant natively.

The light group works well!
Now I would like to control this group with a physical rotary switch but I am unable to either use this relative brightness light group integration or use group to control the switch.
“Living Sync” controls all 3 lights
“Rotary Sync” is linked between the rotary and the Living sync light group.

Hi,

Same issue here. How can I get the relative state be permanent?

Regards, Luuc.

There wasn’t any movement on the original repo the past 6 months or so, so I’ve gone ahead and forked the project and implemented this! I’ve added support to ensure that when turning the group off and back on only the lights that were on before get triggered. Feedback & PRs on the fork are welcome (and happy to eventually sync back to Oscar’s original version here if desired by him). I’m hoping to eventually add a way of setting up and managing groups with the GUI, but that will probably be a bit of a bigger effort and may be better suited to an actual feature improvement in the core integration.
