After the vehicle is mounted, it shows "stationary" status on the platform, but it also shows somewhere else on the map. This is because after the device is installed, the vehicle has been in a stationary state, when the device is stationary, is not transmitted to the server GPS data (to save traffic considerations). This phenomenon is because the device has not yet transmitted the latest location data to the server, the display is still the old location data before. So what you see is still the old location data.
Solution: Please drive the vehicle out to an open area for a certain distance, when the vehicle has movement, there will be the latest positioning data uploaded to the server, and you will be able to see the exact location.
2. If the car is mounted on the platform, it shows "offline" or "not online" status. This is because the device has not been connected to the server, GPS positioning data has not been uploaded to the server, see the old positioning data.
