ignore 0 coordinates

hi,
got something in the log:

2024-03-01 20:04:25  INFO: [T377df513] id: 860501044912117, time: 2024-03-01 20:04:20, lat: 0.00000, lon: -0.00000, course: 0.0
2024-03-01 20:04:25  INFO: [T377df513] id: 860501044912117, time: 2024-03-01 20:04:20, lat: 0.00000, lon: -0.00000, course: 0.0

how to configure the server to ignore this kind of data?
also since it's already in the database, how to remove that?
Thanks

<entry key='filter.zero'>true</entry>

filter.zero config

Filter zero coordinates. Zero latitude and longitude are theoretically valid values, but it practice it usually indicates invalid GPS data.

thanks

I copied your line, entered it to my config and restarted the traccar.service but when I open a device history, there are still zero coordinates shown… is it working for you?

Filtering won't change history. It will only apply to the new data.

Thanks. I fixed it with this MySQL-command:

DELETE FROM tc_positions WHERE latitude = "0";
