Mitsubishi WF-RAC - (Smart M-Air)

Hi,

Great that you are using Homeassistant on ESXI server. (I also use ESXI, with an intel NUC)
How did you install it? With Hacs or did you clone the repo?

You can setup the integration manually by clicking on the + Add integration button in the lower right corner of Settings->Devices&Services in the search bar type mits and select the integration. (see picture)

after that fill in the airco details:

Hope that helps.
Let me know if you need anymore help.
