Animated staircase -- question -- pls help

Dear All,

I have a guestion in regards of this usermod: in the manual i see: “Always switch on when one of the sensors detects movement, even if an effect is still running. It can gracefully handle multiple people on the stairs.”

In my understanding, it means, if the “down” sensor activated, it turns on the segments to up, but if the “top” sensor activated before the last segment is on, it starts to light on the segment from the top to down. – is it correct??

In my case activateing the “down” sensor turn on the segment to up, but nothing happens till the segments are on. If i activate the “top” sensor in this time frame, it does not affect the segments. I guess, this is not the proper way of working.

What do i need to modify? — thanks in advance for your response!
