I've been toying with a variant of this project for my Honeywell home air filters. I have one in all my "big" rooms, and I like to keep them running at a low speed most of the day. But I also have time-of-day energy pricing, and it would be nice to automatically turn off (or at least slow) my air filters during the 5pm-8pm window. This project inspires me to at least look into the feasibility of adding that functiona…
My fan worked fine, so I gave it WiFi

#52I love this - but honestly I was expecting this to end with the fan not functioning due to wifi issues. :)

You should, it is very DIYable! I did it and reverse engineered it myself a while back. You dont need to make a custom circuit board if you are fine with losing the touch controls

#54How much does it cost to get a pcb made with all the components?
I hate soldering but breadboards are limiting.

Holy shit, perfect!

Depending on your air filter you might be able to just use a smart plug, I went down a similar route this summer before realizing that mine would remember their power state and settings when powered off. So now I just have them plugged into a few smart plugs with automations in homeassistant
I would need a device with a physical switch rather than a touch control. Sadly many devices, mine included, have "power was cycled = device is off" logic.

#58>> The PCB was ordered from JLCPCB, where I opted to have most of the components pre-soldered. very expensive, you are committed! :) you should have gone Full Giertz and added a badd little robot arm that turn the pot. esp32 are really nice: hundreds of code examples that do what you want without having to read too many pages. did you use ARDUINO IDE or idf.py SDK?
I was actually pleased with how cheap it ended up: less than $20 USD for the board + assembly + every component. I set ESPHome to use IDF under the hood, you can check out my full ESPHome config for this: https://git.ellis.codes/e/esphome-configs/src/branch/main/vo...
interesting! i tried to order some assembled boards and was told $200+ (US) for only ~20 smd parts.

I've noticed that some things can make the price suddenly skyrocket. Certain PCB specifications for one (though couldn't name anything in particular off hand). The one thing that caught me by surprise was that if I wanted to have JLCPCB solder the ESP32 for me the cost would jump by more than double, and the PCB would have to be physically larger. Something about their "Economic" vs. "Standard" PCB assembly where, for reasons I'm not clear on, the ESP32 could only be done under the latter. I opted to solder that component myself, of course.
