Support for Yonan A/C Units (KT3F-24GW/X1)

[maciekish]

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...

False alarm. Looks like "Coolix" works -.-
