So, after going wild with all kinds of different codes and examples, I now simply made the basics available in Fibaro and we even use it in a combination with our Nest Thermostat and Netatmo. If the temperature goes above 24.5 degrees celsius it will switch on our Daikin. If Nest's or Netatmo's temp goes below 23 it will turn the airco off. The only thing missing with this Virtual device is a way to see what the airco is currently doing, but then again... better something then nothing at all.
And here I have an example for all of you wanting to do a simple ON, OFF, Cool, Heat and Humidify with Daikin Wifi controlled units. You must edit the temperature setting for each value to your liking.
In the local Daikin = Net.FHttp(\"192.168.XXX.XXX\", \"80\") you simply fill in the local LAN IP address of your Daikin Wifi unit (ex. 192.168.1.90).
