After doing the hardware part, intercepting the IR beams and make them play using the ESP8266, I've changed also my Homy3 application in order to accommodate the new device AirCon.
So after the app is starting is identifying all devices.
As you can see there is an AirCon device discovered.
Accessing the AirCon device allow me to turn it On or Off. I've kept the toggle button to display the current state of the air-conditioner.
Perfect. Now I am sure that I will find a nice cooled air in the house by the time I get home.
