Reads and writes data (e.g. power, mode, fan status etc.) from/to a Mitsubishi Heavy Industries (MHI) air conditioner (AC) via SPI controlled by MQTT
Just uploaded a new version v2.6R1 with an experimental implementation of the fan control including 'Auto'. It is based on testing with the [WF-RAC](https://www.klimaanlagen-heizungen.de/mitsubishi-wlan-adapter-wf-rac/). The implementation of the new fan...
I have a MHI KX1:1-series ducted unit (FDU140KXE6F/FDC140KXES6). The unit was supplied with the RC-EX1 remote control, which has a inbuilt temperature sensor and the ability to switch the 'Room'...
MHI has a (new?) WiFi module called WF-RAC. This module is connected to the CNS port of the airco. Then you can use the 'Smart M-air' app to control your...
The MHI units have a precision of 1.0C for setpoint. Additionally, troom is rounded down to .0 / 0.25 / .5 / .75 causing an additional loss of precision for...
Hi not really an issue, but thought you would like to know your base code works with the SRK50ZJX-S1 heat pump also. Only issue noted is the SCK frequency is...
If anyone is interested in an alternative design not requiring a PCB, I remapped the existing circuit diagram to Veroboard. I also swapped out to a NodeMCU module as they...
I've been using the modules with succes for the last weeks. One apparent issue is that if I keep the modules behind the plastic, they get a too weak WiFi...
Hi there, First of all, thanks for sharing this awesome project. I was wondering if you considered using the tsr 1-2450e instead of the non-e variant. The e variant has...
This is an update of the existing KiCad PCB. It is converted to (big handsolderable) SMD parts, that are easily and cheap to source from LCSC. More importantly, it adds...
