Notes: This KoolKing model is the same as the MrCool 3rd Gen mini split that is sold in the US (with the obvious C → F change), and it has exaclty the same module as henkvdt’s here
I used the DIY ESPhome dongle with @aceindy yaml file and it works good. Except that it shows as 0 for both Power and Humidity, even if it sees it as available characteristics.

Did anyone have tested with:
Midea Breezeless MSFAAU-12HRFN8-MSFAAU-12HRFN8
or
Midea All Easy Pro Nordic UV MSEPBU-12HRFN8-MOX330-12HFN8-UV
Any help appreciated.
As stated in the title of this thread, and two times afterwards, please ask questions in the corresponding thread:
This thread is to keep a list of all known working models.
Thank you very much! 
This is exactly the same PCB as in a Samsung AR12TXHQASINEU indoor unit( European market)
So that should work too.
But where can I get it? The ESP module and do I need to alter some wiring or is it plug & play?

I have the same air conditioner, is this a plug & play device or do I need to alter wires or code?
And what is the (Android) app for being able to use it?
