Merten 4 way switch

Hi all,

Hope someone can help me out.

Im trying to set up my Merten 4 way switches, and succeeded for 50%

I can set direct associations to switches or dimmers, to both left and right pedal.
This must be done using a special trick, by clicking in a certain pattern. This way one extends the write timeframe on the Merten push button.

But now I want to make the last step…
I want to use left pedal as a scene controller and configure a scene to it.
The right pedal should have a direct association to a light.

I can only succeed setting or the scene to the left pedal, or the direct association to the the right pedal.
But as soon as I start to combine them, only the direct association keeps working…

From here I’m stuck!
So is there someone who can help me out on this?
