Position Filter
It might be helpful to know what exactly you've already tested.
I have activated filter.enable. Also filter.invalid and filter.zero. In my case it is a bit difficult because there are no zero coordinates and they are not invalid.
I still have another question where I did not find an answer. Are these filters active when receiving the tracker message or when querying the database. Therefore, can such a filtering of the existing database entries be achieved?
How can I filter out bad positions like these?
All tests with filters and search in FOrum led to no result.
