Hello, ErnstFrei .
If you need to see your vehicle in the application, then you must have a tracker installed on it.
To get the IP and port, it will be enough to create a unit in the system. Use basic Vjoycar device type. – https://gps-trace.com/en/help/ruhavik/units
And direct your device to the server and port specified in Unit settings on the Hardware tab. – https://gps-trace.com/en/help/ruhavik/unit_settings
As soon as your device starts sending data in messages to the server, you will immediately see it in the application.
If you have a problem with device configuration it is better to contact the device manufacturer or dealer for the tracker settings.
Also, information on settings can be found in the instructions for the device.
If you have any questions during the process of setting up a unit and device, do not hesitate to write to us.
