Node Red by far gave me the best automation for numerous lights. X minutes after sunrise, it iterates every light that is on and calls turn off with a fairly long (2 min?) transition time, so the lights all gradually fade off.

It's been running for years without me needing to touch anything, it doesn't care if you replace/rename any lights, and the slow fade when it's still getting brighter outside makes the change invisible.

I'll bet you could do the same thing without Node Red, but nowhere near as easily.

How many people actually want curved walls though?

People who hire fancy architects. Not people who have to work for a living.

I had to pay for a static IP just this week because it turns out the new ISP uses CG-NAT.
