Hey!

There is a program that you can install on your computer to remove all the blue light from your screen in the evening. The reason for doing that would be to feel more chill in the evening. And for the morning you would like the opposite, more blue light even though you wouldn’t have the lights on max of course.

I want this for all my lights connected to my Homey. Have anyone done anything similar that can point me in the right direction?

Thanks in advance!

Are you illuminating your home with RGB bulbs?

I guess it depends on the type of light, but perhaps you can gradually dim the blue channel over a certain period of time. You can use the [Chronograph app](https://homey.app/en-gb/app/nl.fellownet.chronograph/Chronograph/) to create a transition, and use the transition value in a flow to slowly dim the blue channel.
