Dashboard display negative distance values
The Dashboard displays negative values. This issue happens at midnight when the daily distance reading is reset until the vehicle travels a few kilometers.
The reason for negative values in Dashboard is that there is an odometer correction made during midnight when data gets reprocessed at midnight schedule to speed up reports execution during the day.
You only get this problem when you use GPS distance as Odometer.
This issue is not affected by devices using hardware odometer.
You can read more about odometers in how the odometer works in GpsGate.
Change your odometer setting from GPS distance to OdometerAcc in the Device Mapper.
Follow the steps described in this guide to achieve this.
