KNX cover - travel movement state

When integrating covers with the KNX system, is there any way to know if the blinds are opening or closing?
Thanks

Short answer: No.

If you are a developer (or like to fiddle with stuff) you could test the xknx custom component (https://xknx.io/home_assistant) from the PR https://github.com/XKNX/xknx/pull/259 . It would be added there.
