Just to pile on here, I have two things in progress:
1 - rev engineering what the ip based com’s are, seems VERY simple but annoying to replicate
2 - rev engineering what the keypad is sending to the controller, so far I can duplicate a few menu items, my goal would be a physical MITM between the keypad and the controller.
I have a good track record of this stuff I did the first rev of the Balboa spa long ago and a couple rev’s of the Mitsubishi splits, commercial dehumidifiers, and a few other rev engineerings. The good news is serial serial serial
Adding in energy use and graphing heat/cool times is also my to do list with this.
I HATE cloud and I HATE having 50689 apps to do simple things, so their closed system will not stand!
