I decided the default direct connect device type wasn’t good enough, so I got a little crazy. Here’s the end result.
All Hue A19 bulbs (both new and old) are actually extended color lights, so you can use the color temp portion of Zigbee and the bulb goes to “White” mode for a pleasing array of natural white light. I also brought in some color naming from the Osram Gardenspot devicetype and applied it to the main tile. The last trick is that the two white presets in the color picker, go directly to 2700K and 3500K white instead of trying to approximate it via hue/saturation values.
