Thanks. 😀
I had to use 4 different sources to make my project work.
It wouldn’t be nice to force others to go trough the same amount of trouble when i already have the files.

I made a git repo with the schematic and yaml file for you, if you have any questions feel free to ask.
I may not know the answer, but i’ll do my best to help.

I actually have a working’ish prototype of this project laying on my table right now.
It’s a 120mm noctua fan being controlled by pwm i relation to the temperature. It also has an oled screen to show temp and fan speed. All controlled trough home assistant via esphome.
I say working’ish because the temp sensor i’m using (dht11) is unreliable and is messing up half the time, so i’m looking into buying a DS18B20 instead.
I’d be happy to share schematics and code if you’d like it.

I’m happy to help.

I don’t know much about WLED, but from the other comments here it would appear so. And i think it’s also what makes the most sense.

If i’m understanding your question, what you’re looking for is Ohm’s law
Amp = watt / volt
1 / 24 = 0.042
You want milliamps, so multiply by 1000 giving you 42mA per IC
