Works great with Home Assistant and units equipped with SK102, SK103, SK105 Midea dongles, such as Midea Blanc (MSMABU-12HRDNX-QRD0FGW), Midea Blanc (MA-09NXD0-I), Midea Xtreme Save (MSAGAU-09HRFNX-QRD0GW). It is also compatible with units based on Midea but sold under different brand names, like MDV. Some older units do not come with an extension cable to plug in the "USB". In that case, an extension cable is needed: "USB Female Terminal Data Cable PH2.0 4P 2.54mm USB To Dupont 4 Pin Adapter", which is then plugged into the CN3 port of the control board of the AC.
