What does the color indicate for the status of the device?

What does the color indicate for the status of the device? Is there a way to control it / change it?

I tried checking the documentation but did not find what it means to be green, red or gray (which is what I see as status in the traccar web).

Thanks!

The color indicates the connection status:

• green - online
• gray - unknown
• red - offline

You can override it using the "color" position attribute.

Regards, Anton, could you tell me where that attribute is, or in what file, thank you very much
