Wireless M-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.

collects data by devices sending their data via wireless M-Bus

forwards data to your IoT cloud backend via mioty®LoRaWAN® or Sigfox

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

STACKFORCE develops and maintains an Industrial LoRaWAN® Stack.

STACKFORCE is an experienced integrator of Sigfox.

STACKFORCE ​​​​​​​develops and maintains a mioty® Stack.

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!
Using the innovative Bridge will save you time and money!

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.
