Visibility of shutter/cover Card

Hello. I want to make use of the visibility feature for a simple Shutter Card. I want to show the cards only when the shutter is „Not fully Open“ (100%). When I use the condition „State“ the Problem is, that When the shutter is Open between 1% and 99% the State is also „Open“. So trying the conditon „Not Open“ Shows only closed shutters (0%).

Using the condition „numeric state“ brings the Problem that the positions are no Numbers because they are percent (%).

How Can I easily fix that Problem. Did not want to make Helpers or something.

The documentation is Not that specific on this topic. Forum Has Not yet shown the Problem with shutters.

Is there Andy Client to get this?
