Hello, Klaus ,
To direct your device to our server, you have to create units yourself in the application. It is not difficult and can be done in a couple of clicks. There you can select your device type.
Here is all the information on creating a unit with detailed illustrations. – https://help.gurtam.space/en/article/how-to-create-a-unit
After you create a unit in the application, you will see the server address and port to which you need to direct your device.
There is nothing complicated in this at all, we simply do not have the opportunity to specify the server and port for you, since for each individual unit in the system there can be its own server address and port.
In any case, if something does not work out for you, you can also write to us firstname.lastname@example.org.
Do not forget to include your login, unit ID and device type in your email.
