I used 1 Khz. I ran into issues because I also wanted to see if i could get this to work on another ESP32 system. It was either Tasmota or OpenHASP. I ran into multiple issues with that. First, my oscilloscope couldn't handle the 10Khz that I think they were using and, as you point out, there's...

Found it! So it was a transistor - I can't remember the specs, but it's fast enough. I bought all the parts from Amazon. The ESP32 is a WROOM, so be aware that the pin numbers might change depending on which version of the ESP32 you use.

What I do remember is that the fan provides +10VDC through the USB-C connector. That's helpful here, but bad otherwise. For a USB-C connector, most hardware will expect +5VDC, and NOT 10, so when they do this, that could break a person's hardware. Here's what I remember about what I did: I...

I did get it working - basically I used the info from here and got a schematic together. I don't have my notes here - I'm at the workshop and they're on my the computer in the house. I don't have a PCB or anything, I just have it running on a breadboard using the ESPHome config given.

I had to set this aside to get some other work done, and now I'm finally able to get back to it. I want to be sure I'm doing things right before I hook my ESP32 up to the fans. I bought a low end o-scope and used it to verify the square wave signal from the ESP32. So, for immediate questions, I...

My fans come with the Controller 68 (or 69?), which has a speed control and that's it. No bluetooth or wifi on this model, so if I want to use the ACI systems for any control other than manual, it's going to cost me a chunk to get a controller and anything else to go with it. That's going to be...

I got my UIS to Molex adaptors today and I also went down to the barn and checked the cables on my fans. The adaptor has a USB-C female on one end. I took a charging cable (USB-A to USB-C) off my charger and plugged the USB-C end directly into the USB-C female on the ACI adaptor. I didn't have a...

Ah - so the config people are using specifies it's a PWM signal, so the ESP knows what to do from there. Thank you for the explanation! Ah - okay, I got it now. Make sense. Can I do the same thing with an optocoupler if I get one that can handle 10V? I could use the 3.3V on one end with the...

Good point. Looks so much like a USB-C plug that I figured it was. I'll have to check on that. Didn't someone in the longer thread say something about it being a USB-C plug?

After studying this entire thread, I have a good idea of what's going on. I still have a few questions that have been addressed, but I'm not completely clear on the answers. Also, while I understand what PWM is, I'm not fully clear on how the ESP or Pi is controlling it and what the ESP, the...

Thanks! I'm happy with the result. Also love how the "drawer" works. The fans are mounted to plywood (nice high grade - left over from when the house was built), and it's on a drawer slider, which is mounted to two boards, one on each side, which are also mounted to drawer sliders, so it's a...

By "other thread," you mean the one you linked to? I bought one fan around February, '23, then a 2nd one (when I realized I'd need 2 for what I'm doing) 4-8 weeks ago. Both are on this 7wire system that the linked thread is about - so it's a big relief, knowing they moved from one system to the...

Okay, feeling like a frustrated idiot here. I had opened up the wiring compartment on one of my fans back before installing them. Here's where I have them: And when I open it and pull the platform out, I get this: I had one photo I had taken of the wiring in the box and, from my view, the...

Thanks! I've posted there. I'm not clear if my motor is the same as what they're working with. I think it may be different and I've asked about it there and am waiting for a response - haven't seen any activity on that thread for a couple days now. That's the ONLY place I've found good...

I'm using a different type of fan, an AC Infinity Cloudline Pro S4. I've posted about it in a separate thread and someone referred me to this thread. I'm not clear if these fans will work with the system people are working with on this thread. I've included a few pictures of the types of...
