I saw a number of people here had trouble getting the iFan04 into flash mode, how did you solve it? I’ve tried different USB cables, installing all recommend drivers for ESP and the adapter I’m using, but no luck.
When I plug just the adapter into my PC it recognizes it, but as soon as I try to connect the iFan04 nothing comes up. The LED comes on and it starts going into pairing mode if I just connect it to the adapter and plug it into my PC, but nothing happens when trying to hold the power button while giving it power.
From that single frontside picture the USB TTL device doesn’t have a regulator on it which means you might have missed that it is basically a requirement for this board. Sonoff Ifan04 - ESPHome working code - #61 by NonaSuomy
It finally worked after spending the entire afternoon trying to flash it. I tried with a Prolific TTL and later switched to a Arduino UNO as an adapter, both with an external bench power supply. In the end the problem was forgetting to hv the 3 grounds together.

Hi everybody!
did somebody create a esphome custom component for the I2C MOSFET dimmer from krida?
that’s the arduino code:
would be nice to control the device with esp32 as I2C master
unfortunately no info from seller. little more guides and support couldn’t do so much harm especially regarding home assistant & esphome known as really very popular, more or less nothing to find …
@haydon So my Ifan04 has been functioning great with esphome since completing the process describe above here. And I’ve even got it managed through the esphome addon in HA now. So all good there.
I’m encountering an error when trying to use the device in HA Scenes, and wondered if you might have any suggestions. When I try to activate a Scene which has the Ifan04 fan set to a speed greater than 0 (i.e. on vs. off), the following error is thrown:
Preset mode is not valid, valid preset modes are: .
This wasn’t happening when I first set the device up in scenes and tested them. But it is happening now, and so the fan doesn’t run with the other fans I’m trying to synchronize it to.
Any thoughts on how I might further troubleshoot this?
I actually bought the one above previously for another project and have been unsuccessful with it. The regulator and CH340 is a key note thanks! I’d love to buy from Amazon instead of Ali to avoid the very long wait. I think this one has the regulator. Would someone be willing to confirm or deny my intuition here?

Awesome, thank you! I have the ifan04-L (previously ordered the exact link you sent) is there any version differences I should take into account before giving this a shot?
This is what kept if from being valid. I currently have it commented out and it validated and loaded fine. I noticed it was from the section that translates the remote actions back to HA so I figured I could go without it for a while. For some reason it was hanging up when others seemed to get it easily (IE you haha)
