KNX setup and issues

I have uploaded my knxproj file to homey and it has the address of my IP Router, but I am unable to control any devices. I just get an error when trying on/off. Any help would be greatly appreciated. I bought homey because it seemed like the first/only home hub that spoke to KNX. Now we really need some development to make the app and install easier.

Can anyone walk me though the process of setting things up? I am using an HDL IP Router.
