Done this for the past 6 years running a combo of cheap zwave color temp adjusting lights, smart things, and a smart things app automation called circadian daylight.

Makes the evenings more laid back and I'm able to sleep a bit easier. Well worth the effort to get it setup.

What kind of bulbs are you using? Most of the z-wave ones I found do not have great CRI and the cheap ones generally don't support white color temperature at all (falling back on some RGB).

I have recessed lighting in my home with non-serviceable LEDs.

I would love to find a replacement that supports multiple color temperatures.

Suggestions solicited!

My house has recessed LEDs throughout with hardware switches to control the colour temperature between five options. My approach has been to set colour temperature based on room (warmer in living rooms, basement, cooler in kitchen, etc.). I then use separate lamps or light fixtures to fill in where I want different colour temperatures. (Bedrooms and offices have ceiling fans with warm lights as well as some hue lights with colour temp that changes based on time, kitchen and dining room have warmer pendant lights / chandelier, etc.)

Some manufacturers make dumb bulbs that dim-to-warm, which are very nice for some applications. (Dim-to-warm recessed LEDs exist, but they weren’t optimal for my application.)

I just replaced everything with high-hats.

The decision was made easier when the living room ceiling collapsed on me.

Looks like I was mistaken. We've replaced all the zwave bulbs with Sylvania Osram zigbee-based ones in our new place. Cheapo stuff, but they don't flicker when adjusting temperatures/brightness:

Smart things has been a bit of a mess lately with their automation related to zigbee. They've got a hotfix rolling out, but it's been a month or two of random lights turning on or refusing to turn off.
