Quit naming everything by the room they're in. Name them by who will be using it or North South east west, Up, down, left, right, inside, outside, front, back, David's, John's Bill's, Angie's, mom's dad's Oldest, younger, anything but things that are the same. If you want to name a group inside any one skill, by a single name, like say 4 Hue lights by "Bedroom" group name, that would make sense, as long as you don't name another group "Bedroom 2" or some close name like that.
Be creative and keep the names is distinct as possible until the AI gets better... these are all still relatively new and AI voice and context issues are still being worked out. So everything you can do to avoid similar names of ANYTHING, is helpful. The AI cannot think... you can.
I have had to change bulb names due to similarity in one case. I had one bulb named "his lamp" and added one recently and named it "east lamp" and the AI cannot distinguish between the two every time... Had to rename one to eliminate the confusion.
