Knx - Homekit HEX Control - jorgejglopez - 22.05.2020

Hi, I'm trying to control my HVAC system with KNX and homekit but I don't know how to manage it.

Homekit send the comands in HEX and I receive the code in one address.

I need for example to Turn On Lounge HVAC (1/7/18) and Put the HVAC Machine in Cool Mode (1/7/2) when I receive the code 43 6F 6F 6C 4F 6E (1/5/10) but I don't know how to create the script.

1/7/18 - 1.001 Switch
1/7/2 - 20.105 HVAC Control Mode
1/5/10 - HEX

Can anyone help me?

Hi,

Set object 1/5/10 to a 250 byte object and you (probably) will receive the value “CoolOn”

Then create a event based script on object 1/5/10 like this:
Code:
if event.getvalue() == "CoolOn" then
  grp.checkwrite('1/7/18', true)
  grp.checkwrite('1/7/2', 3)
end
Object type 20.105 does not exist in the controller but its just a 1 byte value so you can just use a 05. 1 byte unsigned integer  object for this.

Some 20.105 values to test are values are: 0=Aut, 1=Heat, 3=Cool, 9=Fan, 14=Dry

BR,

Erwin
