rost I tried getting documentation, no reaction. Chinese companies just don’t always understand English well. I’m an end user, my request does not have any weight to just about any Chinese company.

I just gave your support-Email access to one of my ST-903 trackers which is online with GSM and GPS. I hope engineering can have another look. Battery voltage is very important for those trackers that are not connected to vehicle power.

I certainly hope that there are no different protocols depending on the IP address hardcoded in the trackers!

      Hello, Trkr ,

      Thanks for the email!
      We will check the data from your tracker and answer you, please wait.

        I connected another Sinotrack (ST-901) to demo3.traccar.org. See screenshot.
        With 12V on, Io4 is 12481.
        With 12V off, Io4 is 12063. Unfortunately, none of the values goes down slowly (like a battery voltage would).


        Hello!
        Please filter wrong message “from future”. This message broken current position on map.
        This wrong message (current time + 3 hrs and position.valid - false in toolbox), sinotrack st-901m sends one time when power on. And next 3 hrs ruhavik show current position from this message, instread actual.

          andyworx Hello!
          Thank you for reporting this issue. As far as we can see, you probably deleted the unit and created it again, so this message doesn’t exist at the moment.
          We will look into this issue and try to fix it.

            Hello!

              andyworx Hello!
              At the moment, the application displays just data that is the last one by the time of the message and they are not processed additionally.
              Thank you for letting us know about this issue, we will work on a solution to check the validity of the last location. This will take some time to fix. We are sorry for the inconvenience.

              For your part, you can additionally check the tracker settings. Perhaps there is an additional setting that leads to the sending of such a message?
              If you have additional information on this model of the tracker, for example, a protocol, then you can send it to us and perhaps we can add this model to the list.

                  JorgeBotteri Hello!
                  Could you clarify if you have a problem with creating a unit or connecting a tracker to it?
                  If there is a problem with the connection, then please try using the ID in unit settings as 0 + tracker ID.
                  If the problem persists, please write to us about it in more detail at support@gps-trace.com with your username, IMEI and tracker model.

                    I’ve been getting battery percentage on my ST-903 for several weeks now.

                    Awesome, thank you for the effort!

                    I had to delete and re-add them in Ruhavik.

                    I’m also using ST-901 and I don’t see the battery percentage yet.

                    Did you plan to implement battery percentage for all Sinotrack models?

                    Also, please consider adding the ST-903 explicitly. It works as an ST-904 but less guesswork is always better.

                      Hello, Trkr ,

                      Please write us an email to support@gps-trace.com.
                      In the email, please specify login and unit ID with Sinotrack ST-901 device, we will check it aditionally.

                      Also, if possible in the letter, indicate a link to this topic on the forum.

                        The Sinotrack ST-903 has been added to the Hardware category list. Now in the Unit settings you can select this device in the list.

                            Hello, grad63 ,

                            These devices are already supported in our application.
                            The battery percentage has also been corrected.
                            You can already change the device type in the settings of your unit!

                            If you have any questions, write to us again!
