Hey there!
I have a remote for a desk light that I’ve modified with an esp but I’m running into an issue with the color temp. Basically the remote uses a rotary encoder for the brightness and color temperature which means I have “press” a button x number of times. I’ve gotten the brightness working but now the issue is that I can’t figure out the color temperature. The temperature range is 3000k-6500k but only has 15 steps in between the two. I currently have a number slider that works but I can’t integrate it into a light entity. I’m trying to figure out how I’d convert it so 15 would be 3000 and 0 6500k. Please ignore the code since I had to mash some scraps I found together. Please let me know if there is anything I could improve!
