Hi xtrex,
I have a busch-jaeger wall controller which is basically a Duwi 5460. I assume it works the same as a 5443 as you have.
I have the same problem you are having. The work around for me is to pair the Duwi with one or more appliances (light). Vera can see the state of the appliance and you can control scenes from that. The drawbacks are
1) You have to have an (additional) appliance device paired with the Duwi
2) I use Duwi appliances and they have to be polled, so the state change is only detected after tens of seconds
If you find a better solution, I'm interested
