Support for Yonan A/C Units (KT3F-24GW/X1)
Describe the problem you have/What new integration you would like I have 11 Yonan A/C units which i can not replace and are not supported by ESPHome climate. I do have some programming experience but 0 experience with IR/RF, and cannot make any sense of the codes for the life of me. I don't have a problem writing a platform for Yonan but i need help understanding the codes first.
Please describe your use case for this integration and alternatives you've tried: It seems like the remote (RG57A2/BGEF) is the same across multiple brands, including Midea. So i tried the Midea platform but that didnt work, but ESPHome is able to properly decode the commands from my remote with the Midea platform if i set up a receiver... I'm also able to capture and replay codes using remote_transmitter.transmit_toshiba_ac and rc_code_1: 0xB24D9F60A05F, the Yonan reacts properly to that.
This is ESPHome receiving a command properly from my original Yonan remote. I assume it says "sending" even though it's receiving because it's sending this data to HA? Either way, this is me pressing a button on the original remote, and HA interface updates with correct temperature and mode, same as my AC unit and remote display.
Additional context Here are some codes i captured, but cannot find any pattern in them:

Any chance CN2 or CN3 is unlabeled UART? There is a UART midea platform as well...
CN3 is for UART needed for midea component. Looks like UART goes directly to indoor unit pcb. Trace the traces. Get gnd and try to find rx/tx. Be careful, it's probably 5V logic
