I’m basically looking to recreate BrainLit’s circadian rhythm matching lighting, which they call BioCentric Lighting . I’ve been to their office here in Lund and essentially it adjusts color temperature and brightness to match the sun as if every day was April 16th in southern Sweden. [image] [ima…

Does this help with your idea? [image] Natural sunlight color temperature Questions & Help Hi, I would like to set the color temperature of my bulbs to the natural sunlight color. Is there an app for that? Or some well known algorithm, which would calculate the temperatu…

Thanks! I’ve gotten this far as to calculate both color temperature and brightness to a certain degree for a single light. It’s the way forward, scaling it to every room of the apartment that I’m uncertain about. :slight_smile:

Can you share how you calculated the light temperature?

It’s much simplified and because I never want the lights to be completely dark, there is also a minimum, but it does serve its purpose well. :slight_smile: :point_right: gist

Hi. How is this going? Can you share the calulations?

Yes, follow the finger :point_right: in my previous post. :slight_smile:

Hi, Just discovered your script and immediately packed in homeyscript! But I still have some questions: which flows have you made? Do you let homey do the script every second? Which flow did you create so that the temperature etc. are retrieved? Are they stored in a logic? Definitely want to h…

Updating the brightness and color temperature values every minute seemed sufficient to make it transition smoothly throughout the day. They are stored in the Better Logic app. Here’s the update flow, which also creates dimmed variants for certain lights. https://homey.app/sv-se/flow/kUn5ZA/ Then …

thank you for the answer, since yesterday I already did it though :slight_smile: However, I noticed something and that is when I test the script, the shows me a different system time. Now, for example, the script says: At 15:55:05 Day progress: 66% CircadianRhythm__temperature: 0.04 CircadianR…

Oh, yes. Completely forgot about the timezone issue in scripts since Homey v5. I’ve updated my gist with the hack to fix it. Now, this script should use the correct local time. In the first Flow I create different dimmed versions of the current brightness because sometimes it is too bright, whi…
