ONKYO Binding ongoing state update

Hi to all of you.

I run OH on an Odroid U3 and i works pretty fine.
I control my Onkyo AV receiver via KNX sonsors.
The problem is, that I get ongoing state updates which drives my traffic to the top as you can see in the sreenshot.

Is there any possibility to make this work better or do I have to live with this issue?
