Perhaps I’m lost in translation here! 
But I try a heads-up for NodeRed
In my linked thread above I pasted the “node”-sourcecode, which you can just copy and paste into a node in nodered.: openHAB-Binding for KIA/Hyundai (PH)EVs? - #5 by binderth
Nodered is flow-based, which means you have to have an “entry”-point and from there the “flow” generates more and more information.
So there’s a “inject”-node that triggers itself every 15mins in my case. That will then activate the next node connected “car-Full-Status” node with the “cache” option and from there it shows.
If you know, how NodeRed works, then it’s more straight-forward as coding…
