If you feel like taking on a project I’d say go with making your own adapters and bring it into something like home assistant https://github.com/SwiCago/HeatPump cost me around $150 to get these set up for my 8 splits.
I went this way, as well (though I didn't spend anywhere near $150 - it came to under $5 per mini-split ordered from AliExpress, plus $11.50 for the programming tool from Amazon [including shipping and taxes]). It works really well. I can even use the remotes, if I want to, but the remote won't be updated with the state of the mini-split if I use Home Assistant to adjust settings. Home Assistant will get an update of the state of the mini-split if I adjust settings via the remote.
More accurately, I'm using this repo that supports ESPHome and Home Assistant.
The only issue I have is it doesn't seem to let me control the horizontal vane, but I may have an issue with the config somewhere.
Well I didn’t have any of the required tools at all and to be honest that $150 probably includes some of the wrong pieces that I ordered lol and never returned lol
You might also need to add the additional fan speed options. My testing showed I was missing "diffuse" and "middle". You can figure it out by seeing what the esp logs show when you set the fan speed of the remote to each level.
You could try doing the same with the horizontal vane, I haven't tested that yet.
I hadn't tried checking the logs while using the remote. Thanks for the suggestion. Unfortunately, when I press "Wide Vane" on my remote, I don't get an update in the logs about it. I do see updates when I change the mode or fan speed, as well as the vertical swing setting.
