I have a problem with the Joycon EXC and my Skoda Octavia II rotary knob volumen control.

The Next and Previous Buttons works very well but i dont know what i can do with the rotary knob. The CAN-Bus Scan generates following:

i marked the event, i rotate the knob in red.

It changes only the value which looks like the volumen level. it goes from 1 to 12. The first datablock is not on every rotation 13, i dont know why and the biggest problem, that i dont know if i scroll up or down.

Some ideas here maybe?
