I managed to connect directly to a brand new, single purchase LUX bulb, so we can talk to some hue bulbs directly, but not ones from a kit, as they're pre-paired with the hue hub and can't be reset. I'm surprised the Cree bulbs don't work in one way, but we haven't had anything with the Atmel chipset they're based on so far, so it could be that they're doing things a bit differently. I'll make sure we get some asap.
