here's my S6 configuration working good here on a esp32+ L298n Mosfet driver ...

The solution I came to doesn't require any other components other the the a PWM signal, an opto and some resistors. Been running very stable with multiple speed changes for over a month now without issue.

I honestly don't know. Try it both ways and report back if one doesn't work.

Yes, you can add two, but need them on different pins. When I was setting up my fan control, I actually started with two light controls and was dimming two different lights before I started testing the fan. Your code will look something like this: output: - platform: ledc pin: 23 frequency: 1220 Hz ...

A bit more tweaking, and I think I am happy with what I have: PWM into Anode of optocoupler and 2.2 ohm resistor from cathode to ground. Yellow "pwm" into the collector of the opto and emitter to 1k ohm resistor to black (ground) of the fan. Yellow is pin 2 of the female molex connector on the end o...

I got in the ball park with a simple solution. I have a https://datasheet.octopart.com/OCP-PCT4116/E-TR-Lumex-datasheet-135311.pdf I have PWM into the Anode, 75ohm resistor from cathode to ground of the board. On the fan side, I have yellow "pwm" connected to the collector via a 2K resistor, and the...

I do not have the equipment to be able to tell if this measured voltage is PWM or if its straight DC.

Borrowed a multimeter that can measure Hz and Duty. Yellow to +10v (red) and yellow to ground (black) are both are at 5K Hz. Duty changes as you might expect as speed goes up and down.

Greetings, I am working on automating my ventilation through ESP home and esp32 boards. I can already dim my hlg quad boards as needed with this, and I have been trying to work on my fan and can't quite get it to 100%. My fan ( linked at the bottom of the post ) comes with a simple button controller...
