Not the person you asked, but i have a mitsubishi electric heatpump, which i have hooked up to homeassistant via an esphome library. It has a header on the controller board that you can connect to.
Normally the header is for their $200 controller and app, i spent $10 on the parts.

I think i better start mirroring the repo...
That's amazing. I love such open source projects! I love the Lemmy, Home Assistant and Open Source community.
I have a diy thermostat project (really a multi-zone hvac setup) that I might pick back up given what's going on.
It kinda fell by the way side after my 3D printer started having issues.
I did the same thing for Panasonic ACs if anybody wants to get rid of the cloud: https://github.com/DomiStyle/esphome-panasonic-ac
Might just mirror that repo to be safe :D
I installed this same system a few months ago. It's been fantastic - responsive and intuitive. The 5V pin in the CN105 connector means no external power or wiring is required. We haven't touched the remote since it was installed.
Yeah, its great. My only complaint is that you cant set the vane positions. And the temp sensors are a bit meaningless due to the height on the wall.
I intend to investigate the vane positioning in the future.
