Frequently asked questions about hardware in Wialon

How it works?

The AVL hardware installed in a vehicle figures out the location of that vehicle with help of satellites, gathers data from various accessories and sensors and transmits the data through a cellular or satellite network to Wialon data center. This data can be interpreted to monitor in the Wialon web interface the whereabouts and other parameters of a vehicle in real time.

Frequently asked questions about hardware in Wialon

Integration of new hardware

We’re ready to support a new device by customer’s request. All you need to do is to email us at Please specify the following information in your email if possible:

  • Share your plans on project where you’re going to use this device;
  • Specify device model name and the manufacturer;
  • If you’re in contact with the manufacturer and you have an opportunity to request the device communication protocol, this will speed up the integration process a lot.

In case you don’t have information mentioned above, don’t worry – we will contact the manufacturer ourselves and try to get whatever is required for integration.

The integration of LoraWan, Sigfox and other similar devices is the same as for any GSM hardware. If the device is not integrated yet, kindly contact us at

At Gurtam we do not sell any hardware devices. We’re the software developer only. Nevertheless we’re trying to inform our customers about various hardware compatible with Wialon platform.

Therefore to get the device you’re interested in, please contact the manufacturer or your local supplier.

You option is Wiatag application – our proprietary software tracker. The application serves for basic tracking and efficient mobile workforce management.

Wiatag is absolutely free to download and install on iOS/Android devices.

We recommend you to use Wialon IPS protocol. Wialon IPS communication protocol was developed by Gurtam for personal and vehicle GPS/GLONASS trackers, which send data to satellite monitoring system server over TCP.

Wialon IPS protocol is freely distributed under GNU FDL and can be used by manufacturers of GPS and GLONASS equipment as main protocol for data transmission between GPS/GLONASS trackers and communication server of satellite monitoring system.

Our goal is to support full trackers functionality in Wialon. We remain hardware agnostic company and do not distinguish any manufacturer leaving the choice to our customers. When choosing hardware you may refer to Gurtam rating of manufacturers or decide on any other device even if it is not integrated with Wialon yet.

In most cases there is no need to integrate additional hardware with the platform since they work in conjunction with a GPS tracker. Therefore if the tracker is integrated with Wialon, you can connect various sensors to it.

In case when a sensor has its own GPS module or works through transparent channel, integration might be needed and we will list it as a separate device type in Wialon.

Hardware configuration in Wialon

To check device unit ID, please use service.

  • Point your device to IP, specify device port (you may check your device port here).
  • When the device connects to the server, there will appear its unique ID in the table of service.
  • Save this unique ID in unit properties. Then redirect the GPS tracker to send data to Wialon.

First, please learn the device user manual provided by the manufacturer or supplier. If you still have difficulties with device configuration, email us at and we’ll do our best to assist you.

Though it is common to set up local time zone on GPS devices, it is not recommended, as Wialon works with data in UTC+0h time zone only. This is a mandatory requirement for correct data display in the system. So please reset time zone to UTC+0h in your device. Whereas, local time zone should be set in your Wialon account.

Yet there is an exception from the rule – GPS watch. In this case you should set local time zone in the device. When integrating such device type we allow for specifying local time zone in unit properties, after that Wialon will automatically adjust it to UTC+0h.

  • Make sure that the balance of the SIM card is positive and the PIN code is disabled.
  • Check your APN, IP and port settings as well as unique unit ID in unit properties in your Wialon account. Make sure there are no extra spaces, dots, etc.
  • Check that the device ‘sees’ the satellites. For instance, if the device is in the office, set the GPS antenna of the tracker outside the window. If the antenna is built into the device case, place it on the sill of an open window.
  • Make sure that you set the frequency of sending data.
  • Take a test drive with the device. Some trackers do not send coordinates if the unit does not move.

If after that the tracker still doesn’t show online in Wialon, please contact us at and we will try to assist you.

General procedure of calibration for an analogue FLS (fuel level sensor):

  • Empty the tank completely. Make sure the vehicle accumulator is charged and will not go flat in a couple of hours.
  • Cut the FLS to the necessary length and install it into the tank.
  • Enable data transmission for the necessary input (for example, Ain1). It is recommended to set a frequent data transmission (like once in 10 seconds, for example).
  • Draw a grid for your future calibration table. There will be two columns – Liters and Volts, and so many rows as parts you divide your tank into (+ O liters row). Write the beginning time of the operation.
  • Divide the volume of your tank into 10-30 parts. Pour portions of fuel and each time write the current fuel level in the tank into your calibration table. Wait 2-3 minutes after each new portion. Continue till the tank is full. As a result, the first column of your table (Liters) will be filled in.

After that follow the instruction on setting calculation table in Wialon.

Raw data storage requires huge drive space and is not of practical value for users.

LBS service

GSM cell based location is a technology commonly used to determine unit position. We call it Location-based service (LBS) where a unit location is fixed by cellular towers’ coordinates.

For data transmission GSM module is to be registered at a network provider cell base station, which in its turn transmits Cell ID and other parameters like lac, mnc, mcc. Some GPS tracker models can send Cell ID in the messages to the server.

In case a unit doesn’t send GPS coordinates to the server, Wialon system picks up the base station Cell ID and searches the coordinates in our own database. LBS service could be helpful in places with poor or no GPS signal, in cases when precise location is not necessary or where hardware without GPS module is used.

There could be a few reasons for it: your tracker doesn’t see satellites, GPS module or GPS antenna is not working.

There could be the following reasons for it:

  • Your device is not able to send LBS data;
  • Your device has incorrect settings. To get LBS data, a device needs to transmit at least 4 parameters: mcc, mnc, lac, cell ID. Please check your device settings and make sure your device can transmit those parameters.
  • You haven’t activated Message validity filtration. In Advanced tab of unit properties tick the checkbox ‘Message validity filtration’, then activate ‘Allow positioning by cellular base stations’ function.

Video hardware in Wialon

Yes, you can! Wialon supports video hardware which allows for real-time video tracking as well as getting video files from the devices memory by command or event.

The full list of supported video hardware is available here.

Video monitoring in terms of GPS tracking is quite a young industry therefore not all video devices are suitable for working with GPS tracking platforms. To integrate a video device with Wialon, it should meet some requirements from our side. If you want to have your device supported in the system, kindly email us at and we will analyze the possibility of integration.
