Wireless M-Bus-to-LPWAN Bridge

Icon wM-Bus-to-LPWAN Bridge

The wireless M-Bus-to-LPWAN Bridge is a communication device which transmits wireless M-Bus meter data to your own Industrial Internet of Things (IIoT) by using mainly Long Range Wide Area Network (LoRaWAN®), mioty® or Sigfox network technology. Therefore, a wireless M-Bus (metering) network is enhanced with the advantages of modern Low Power Wide Area Network (LPWAN) technologies, e.g. reliable data transmission over long distances.

Collects data by devices sending their data via

Forwards data to your IoT cloud backend via LPWAN (LoRaWAN®, mioty® or Sigfox)


STACKFORCE owns the famous, well-known and well-proven hardware independent Wireless M-Bus Stack.

STACKFORCE develops and maintains the Industrial LoRaWAN® Stack.

STACKFORCE ​​​​​​​is a founding alliance member and an engaged developer of the mioty® Stack.

STACKFORCE is an experienced integrator of Sigfox.


What would be more obvious than to have STACKFORCE to combine wireless M-Bus with LoRaWAN®, mioty® or Sigfox to create the wireless M-Bus-to-LPWAN Bridge?

Use our WM-BUS-to-LPWAN Bridge for bringing your existing networks up to date!

Remote Management

Manage the wM-Bus-to-LPWAN Bridge remotely from within your IoT cloud backend:

  • Add or remove meters to be considered for bridging
  • Set the encryption key to enable data filtering
  • Change configuration like heartbeat interval
  • Add, modify or remove data filters to optimize amount of data to be transmitted via LPWAN
  • Temporary switch to class C for enabling quick configuration

All done remotely, from within your IoT cloud backend.
