No devices shown in fresh traccar installation

Hi all.

I've read the troubleshooting guide and verified all of these points. Nevertheless the two devices are not showing up in the devices list. I don't know what is wrong here. Maybe someone else can help?
The installation is a docker installation (I've tried traccar:latest and now I'm running traccar:alpine).

Here some output of the traccar-server.log:

I have no clue anymore. I've also tried to understand what is meant with the "Unknown device" warning. But I'm also wondering that this "unknown device" isn't popping up anywhere in the web frontend.

Kind regards,
Jarek

Unknown device means you haven't registered the device. It can also happen if you registered it after it was already sending the data. In the latter case you need to either wait or restart the server.

I faced a similar problem when first installing - it was more a lack of understanding than anything (for me)

On the main web interface there's a + next to the "Search Devices" box. Click the + and you get asked for a device name, and an identifier. The name can be whatever you want, the identifier is the 805079 (mobile phone?) you see in the log line :

WARN: Unknown device - 805079 (172.17.0.1)

then click save. Refresh and you should see it.

Thanks for that @ScaredyCat.
This was the important hint which I’ve been missing in the docs. (lack of examples based on a server log or whatever).
Maybe anyone could add these details in the documentation for users which get the first time in touch with such a system.

By the way it’s working now. Great server, great tool! I like it!

Thanks.

Have you checked the troubleshooting guide documentation?
