Anyone got smart lighting setups to follow Circadian rhythm? How do you do it?

You’ll need a hub with good automation options. Hubitat is a great hub for setting up custom schedules. There’s also the ‘Day Lights’ community app for circadian lighting. It allows for gradual changes throughout the day.

Philips Hue Dimmer Switch or Hue Tap Switch can control the lights without messing with app control.
