I’m remembering something about this only being possible with the older Midea dongle and that it doesn’t work on the OSK103 dongles the newer units (like the U-shaped one) come with. I personally am using an ESP32 instead of the dongle and it works great but it’s little bit of a project to get working.
i opened the AC unit and see the OSK103. yikes.
just for fun, I plugged in a wifi usb adapter and that did not work. so the OSK103 does more than just a wifi adapter. is there a model number of the older adapter that you know works?
also, how did you get the ESP32 to work? could you please share a link? i found this link n it looks like a lot of work. Support for Midea A/C
It’s not actually USB, it just uses a USB connector but it’s a UART serial connection. So other USB devices aren’t going to work. As far as whether it’s a lot of work or not, that depends on how comfortable you are doing electronics work. It can get a little tricky if you’re unfamiliar and there are easier and harder ways to go about it.
I made these using off the shelf components and just have them underneath my a/c units.
Doesn’t look very professional but it’s really stable and works great.
As far as OSK102, it is made by Midea even though the branding may be different. The only thing I’m unsure of is if there’s a difference in the firmware between an older OSK dongle and a newer A/C that might not allow it to work.
