Adafruit Huzzah 8266 #71

I had been working on the rjdekker model which was well documented. I will swap into your stuff as you seem equally talented, and are active. MHI .

Could you comment whether the Adafruit Huzzah Feather has any chance of running this program?

On the MHI AirCon, mine is a huge 3-phase split indoor/outdoor ducted 160VS but much of the reading I have done on it is favourable. I give it rough chance of working. The wired controller seems familiar in your project.

Sorry that English is my only language.

I put a photo of what I have. Level-shifting would be necessary and understood.

Since Adafruit Huzzah Feather is ESP8266 based I assume it will work. Here you find a list of MHI models confirmed to work with MHI-AC-Ctrl.

Thanks Absalom Muc, If I went with Huzzah, I would need to redo the PCB a little 16 HDR and 12 HDR. It doesn't quite compile, with printf_p constructions unknown, but similar strcmp all OK. I will check versions of everything. The MHI model (2013) certainly has the JST connector, and it uses a wired controller very recognisable in the stuff I have seen. Because it is ducted, there is no Vane/Louvre function. Thanks for your help, Peter

Got the software compiling now. Waiting on a few hardware bits. Covid seems to be affecting deliveries. I think that I may have had an outdated 8266 platform. Thanks for your help, Peter
