ioBroker to WLED looking for the correct value

Hi there. I use the scrolling text effect of WLED. Using the WLED web gui, there is a value for this effect. I would like to control it by ioBroker, but can’t find the corresponding parameter. Any idea? Or is there a wiki / documentation?

Rgds, Uwe

you can use the API mode to set the segment name
BE aware that api on segment Zero might lead to restarts
