Help installation on Unraid

[Daniel-PT]

HI
Im pretty new to making a installation from dockerhub and not the "apps" in Unraid.
It seems like it tryed to "guess" many thins in the variabls.

But 2 questions:
1: Where can i find the installation path? - My outher unraid dockers are installed in the "appdata" folder.
But i cant find installation path?

2: I get thees errors when accesing the grafana site on port 4000
Warnings:
You have to set the URL for the VWsFriend user interface correctly: Go to the user interface on port 4000 and select "Database" > ”Connection Settings"

The engine type of null could not be detected yet. This should happen soon when receiving data. - I cant find the variable to set the "wevconnect" user? is that why?

Some panels need the timezone of null to be set. Please set the timezone here: Vehicle Parameters
I dont understand this error? The timezone is browser?

Sorry if thees are noob questions ;)
Regards !
