M-BUS to LORAWAN Converter

Connect up to 10 energy (heat) meters compatible with the M-BUS standard (smart metering) to the LORAWAN network.


The M-BUS to LoRaWAN converter is an IOT sensor that reads and transmits energy consumption data from energy meters (gas, electricity, heat, water) for Smart Metering projects. This converter allows a reading of 10 “utility counters” compatible with the European standard M-BUS (“Meter Bus”).

Heat meter “Teplouchet-1”, Heat meter “STE 21 “Berill”, Heat meter “ELF-M Teplovodomer”, Heat meter “Landis Gyr T230”, Heat meter “Sharky 775”, Heat meter “Pulsar”, Heat meter “Calec ST II”, Heat meter “Calec ST II_2”, Heat meter “Sensonic II”, Heat calculator “ZENNER_MULTIDATA_WR3”, Heat meter “Pulse STK-15”, Heat meter “Hiterm PUTM-1”

What is the M-BUS standard?

M-BUS - Meter Bus (LORAWAN support)It is a European standard defining the transport and data layers of a communication bus, for reading energy consumption on gas meters, electricity, but more generally also heat consumption meters, water…

The principle is that thanks to 2 wires (as for a telephone line), it is possible to interrogate different connected meters. And so to recover the energy consumption, in Wh (watt-hour), but also coolant temperatures (before and after), the volume of fluid …
The operating principle of M-BUS consists of a Master (here the M-BUS converter to LORA) transmits requests to the counters, the Slaves, by referencing them through secondary addresses encoded in the MBUS-LORA converter.


Like all our LoRa sensors, the 4..20 mA industrial converter has an internal temperature sensor.

Use Cases of the M-BUS to LoRaWAN Converter

  • gas meter
  • electricity meter
  • eat meter
  • water meter

Technical Specifications of the M-BUS to LORAWAN Converter

  • Up to 10 connected meters. Different types !
  • Digital Inputs / Safety Inputs: 2
  • Digital Outputs: 2
  • Built-in temperature sensor
  • Direct data transfer or storage and subsequent transmission.

2 Modes of operation

In transparent mode, the converter sends an M-BUS command to a counter and receives the response.
In query mode, the converter generates requests autonomously.  The following heat meters are supported in query mode:

  • Heat meter “Teplouchet-1”
  • Heat meter “STE 21 “Berill”
  • Heat meter “ELF-M Teplovodomer”
  • Heat meter “Landis Gyr T230”
  • Heat meter “Sharky 775”
  • Heat meter “Pulsar”
  • Heat meter “Calec ST II”
  • Heat meter “Calec ST II_2”
  • Heat meter “Sensonic II”
  • Heat calculator “ZENNER_MULTIDATA_WR3”
  • Heat meter “Pulse STK-15”
  • Heat meter “Hiterm PUTM-1”

Most other M-BUS meters can be supported. But the Converter will send the whole MBUS frame, without formatting / removing unnecessary overhead.

    About LoRaWAN

    The LoRa network, also called LoRaWAN, is a dedicated Data network for IOT sensors. It provides small data transmission on large distances – up to 15 km, while consuming very limited energy, allowing sensors to be operated on small batteries.


    • In Belgium and Luxembourg, Proximus operates a nation wide LoRaWAN network.
    • In France, Orange and Bouygues operate a LoRaWAN network.
    • In the Netherlands, KPN is the main LoRaWAN operator.
    • In Switzerland, SwissCom is the main LORAWAN operator
    • LoRaWAN is available in most Countries (Spain, Andorra, Italy, Bulgaria, Czech Republic, UK, Ireland, Iceland...). Worldwide.

    If there is no LoRaWAN coverage in your country/region, it is also possible to deploy a private LoRaWAN network.

    Contact us if you have questions about the LORAWAN coverage in your region.
