If the unit you buy has an IR remote, you could look into Sensibo as an add-on. I just installed a Mr. Cool mini split, and set up a Sensibo Air at the same time. The Sensibo integration is two parts - Homekit and API from their cloud service. Most of my automations use only the Homekit integration. Sensibo’s website will also let you check to see if the AC unit you’re thinking of works with Sensibo.
