Duewi Switch not immediately updating vera

I have duewi wallswitch. It is allready long paired to my vera. But i have this ongoing problem. The switch switches directly if I press on or off on vera.

But the other way around not. If I switch off or on on the switch, vera notices this seconds-minutes later. All my other switches and devices update vera instantly.

what could be wrong?

this is the switch:
Device #81

That switch does not support Instant Status reports.
So vera will not see the change until it get’s around to polling it.
