Stop IKEA Fyrtur blinds with remote

How is that supposed to work? That’s not really possible.
Have you connected the up/down button directly to the roller blinds? Is that even possible?
Why do you want to stop the blinds at 44 %? Are there certain conditions when the blinds should stop at 44 %? For example, a certain time or a certain brightness?
Please provide more information, I don’t understand your goal.
