No, I was only pointing out a problem with the Ikea Trådfri bulbs. Philips Hue bulbs as well as every other third-party bulb I've used work fine--just the Trådfri ones don't. (There may be others, too, but this is the only one I've used or heard of that chose to implement their color model in this manner, which is not compatible with Hubitat's model.) This is true regardless of whether the bulbs are paired directly to Hubitat (as a regular Zigbee device) or used via the Hue Bridge integration. Color will still work in that latter case when controlled from Hue (but not color temperature, even though the bulbs support that on Ikea's software), but you won't get accurate reporting about the current color back into Hubitat.
Yep, that's the reason!
