In the 9600, is a process to control the Lutron Radio RA RF system. I did not know until I read your post, that the Grafik Eye was also an RF device? I always thought it was IR-ready.

The TSU9600 can control the Radio RA RF Lutron unit. It uses the Pronto RFX9600 extender and via the RS-232 port on the extender, which then feeds a Lutron device, which apparently takes the rs-232 signal and converts it to lutron RF.

The solution is not cheap. However, if you are controlling a lot of lights through out your home, it is probably a reasonable investment. From what I saw preliminarily, it is rather expensive for a few lights.
