Fuel consumption
What is the issue exactly?
After installing a fuel gauge I have the fuel level displayed. But regarding fuel consumption there is nothing displayed when I do the fuel report.
What fuel report are you doing?
It simply means that your device hasn't reported any fuel information.
What do I need to do to get my device to report fuel consumption?
Your device has to report either fuel level or total fuel used. Make sure it's reported with every message or copied over. As for what you need to do to get your device to report it, you have to ask your device vendor. Traccar doesn't tell device what to report.
