I was able to say "set the entryway to cool white" and both Hue lights in that "room" came on to a glaring white. I was able to then say "Make the entryway warmer" and they did change. I was able to make them warmer a couple of times. I also tried "set the entryway to warm white" and it worked as well. I've found though that sometimes it doesn't work, and I have to say "set the entryway to the color red". Weird. Hope you get it figured out.
