I just tried this with LIFX Group of Groups @ [RELEASE][UPDATED] LIFX Group of Groups
Took a while to set it up but it seems to do pretty well. I can fade in and fade out as well as control a LIFX group or a bunch of groups with one group (virtual switch). My lights all turn on at once and works well with webcore after I imported them into the service.
I am pleased with the results!
