The [Sun Events](https://homey.app/en-us/app/com.cyclone-software.sunevents/Sun-Events/) app takes “Sunlight Change” into account. With this value it’s possible to adjust the light temperature and brightness depending on the current position of the sun as explained in [this](https://community.homey.app/t/diy-circadian-rhythm-based-lighting/33348/17) post.  
So it’s not exact the same behavior of the light as done with the script, because “Sun Events method” takes into account the seasons.

Circadian Rhythm Light as @iotnerd wanted could probably have been realized with the app [Splines](https://community.homey.app/t/app-splines/40884), but the app is no longer available.

Otherwise, I don’t know of any other app.
