Windows-based reading software for use with USB receiver WMR-IoT

Walk-by windows software

WMR-IoT is a wireless m-bus receiver, intended to collect data from various devices, working in modes T or S according to wireless m-bus standard (EN13757-4). It is connected to an USB port of portable (or stationary) device like laptop, tablet or phone. The software GinWalk gets data from the receiver and gives the user possibility to easily use the device.

Software is intended to set WMR-IoT devices and to read, decrypt and save readed data. Data can be exported in raw csv files or pre-defined templates.

It is free for use and can be provided by Gineers upon request. Works under 98/2000/XP/Vista/Windows 7/Windows 8 and Windows 10.

General information

In practice, without software WMR-IoT would be unusable. Our software can work in two main modes:

  • read and visualize data for every device in range, which is transmitting data;
  • read and visualize data only for certain list of devices, ignoring all others (for instance specific building/entrance/house)

All data is showed in a table and for each meter user can see the following data:

  • meter/device serial number
  • manufacturer code (3-digit)
  • main value (depending on type of the meter)
  • main unit
  • time of readout
  • date of readout
  • signal strength, in dBm
  • status byte (for some devices some bits in this byte are decoded)

As an additional info user can see also special fields of the telegram, full radio telegram, up to 16 additional values with measurement units, etc. From the things mentioned above important role can play signal strength information. This can be used for fixed networks topology issues. The signal is measured in dBm, which means that lower this value is - better coverage. It is showed usually as negative number.

Except basic functionality, the program offers some useful functions for advanced users:

  • AES-128 CBC decryption, Modes 4 and 5
  • log saving abilities with full radio-telegrams
  • defining of templates for import/export. This is very useful, if the user wants to connect wireless readout with certain accounting program
  • saving readed data in local structure database - automatically or manually. This gives opportunity for simple date-to-date reports in GinWalk itself
  • saving of readed meters and corresponding AES-128 keys. This gives the opportunity to skip loading file for meters readout, because meter ID and AES-128 key are memorized and used automatically
  • time record for each readout

Software can be used free of charge. Regular updates are made and uploaded on our site. We also can do custom changes by request.
