Gira Home automation (KNX)

I have a fully automated home via Gira KNX which is quite a universal standard for home automation and uses a Gira home server that has an interface that is sent to portable devices like iphone/ipad. I use the Gira app to control anything in the house like lighting/heating/windows etc. Integration with Roomie to be able to select a light scene for movies for example would be great.
