Mercedes Me Binding and Sitemap

i tried to implement the Mercedes Me Binding for my EQB, it works somehow, except two things.
First i do not get the info’s from the lights, i checked in the debug and there are no information coming from the mercedes developer app. Any idea’s or experience with it?

Second, i put the information in my Sitemap, but i do only see the Header, but no informations or items, if i use the Basic UI, everything will be displayed, what’s wrong?
