DIY 24-Channel MeanWell LED Driver PWM dimming controller for Home Assistant

I wanted a way to control dimming on multiple MeanWell drivers without using optocouplers and resistors.
I created this github page with all of the details to share for anyone else who's interested in doing the same.
Feel free to post issues or discussions on the github page if you're interested in it.

Edit: oop I didn't put the link in. I made a whole tutorial how to make it (although it's rough draft, feel free to give me feedback or ask questions):

Here is the schematic from the github page. If you're thinking of doing this I highly recommend you read the github page.

If you have questions or issues related to this please respond to the github page.

Hey OP, how much approx would the parts needed cost?

@TechSmartSolutions, @Rocket Soul

have you seen the rak wireless stuff? https://store.rakwireless.com/collections/wisblock-base

you can put more or less anything together with the rak gear its amazing. to mimic what the op has done you would need 1 rak wisblock base, 1 wisblock esp32 core and 1 rak pwm expansion board, approx cost is around $25. no bread boards, no wiring on board power delivery ect.

Love it, how many pwm channels? As you know i have quite a few drivers...

16 pwm channels per expansion board.
im not sure if you can run more than one pwm expansion board per wisblock base/esp32core, because it depends on how many io pins are used by each expansion.

Cobby might be sending me something with 5ch which would do nice for our B space that way i can get my feet wet, but A defo needs a lot of channels. Are you able to do multiple drivers from one channel/output?

Let me tag you back with more experience under my belt. You techy guys always say its so easy but i cant get my head around the first part even so need a bit more hands on first
