Harmony ultimate remote with Homeworks QS

I am in the process of selecting a lighting control system for my home. In the past I have used a third party app such and an IR gateway to control most things from my phone. The installer is pushing me to go towards the route of Homeworks QS, but I am more comfortable with the Grafik Eye system since I know for a fact that integration with third party apps or universal remotes is not a problem.

I can't really seem to find a definitive answer, but will I be able to integrate the Homeworks QS with a universal remote like the Harmony Ultimate? I know there are some keypads that have IR receivers, but aside from those, can it be done through the home network?

Thanks
