I have a Midea duct HVAC that has only the option of wired thermostat remote and it's not smart.
I want to build something smart so I can turn on / off the AC or the heating remotely, but I don't know where to start from and if I can build something or it's something internal that only Midea can do it.
The remote does not have any infrared. I don't know what is that infrared pipe of wires A and B.
The 5 wires are:
- A-B = infrared pipe
- C = +5v
- D = GND
- E = RUN
Model of the remote control: kjr-10b/dp(t)-5b
