How to animate buttons of windowscovering graphic?

Hi,

I try to use a windowscovering imp file for commanding 2 relay on my relays card.

When I want to move up, I click on UP and I send 2 URL on my relay card.

But, the button “UP” is not highlighted.
If I look my devices, I don’t know how are my buttons (my last actions)

Can you look my attached file for help?

no idea?
