KNX module does not read any devices from the ETS 6 project file

I have just bought the Smartha Home with the KNX module in order to integrate with the KNX installation in our home. My KNX project is exported from ETS 6 into the Smartha user interface but it does not detect any devices. Are the any known issues with ETS 6? or experience within the forum about any issues or work arounds to make successful identification of all KNX devices

Any help much appreciated.
