For me the one irreplaceable ‘smart home’ feature is circadian lighting. There are ‘smart’ fixtures that will do this themselves but I’ve found scheduling on a per-room basis to be workable (albeit at times a maintenance headache) for coming on 12 years now.

Absolutely can’t live happily with dumb lights only. It’s not just aesthetics - I believe it has a major impact on my sleep health.

Are you considering as circadian lighting the control of just the brightness and when they come on or also including the change from cool to warm light color as well? The ability to change the color temp of the lights is the killer point for me. Anything above 3600K is a no go for me after sunset

Both! My lights go dim and deep red after sunset but very bright and cold mid-day.
