My Alarm Clock Setup - "Circadian Rhythm" Lights

Configuration
1

Hey guys - I just wanted to share the “alarm clock” I built for me and my kids. The idea is slowly wake everyone up using light. Works pretty well. I had to do it this way as I use insteon light switches - so there is no native transition support. Basically, in the frontend, I expose 3 inputs per alarm:

  • 1x binary to say if the alarm should be triggered and is in progress. Turning it off cancels an active alarm
  • 1x input slider used to set the max brightness
  • 1x input slider to set the number of seconds for the brightness to increase over

I control when the alarm goes off through homekit, which works super well. The script is below. One improvement I want to make is transform this into a utility script so that I dont need one script per person…

Open to feedback!
