WMBus-to-LPWAN Bridge

LoRaWAN Sigfox
WMBus-to-LPWAN Bridge

Use our WMBUS-to-LPWAN Bridge for bringing your existing networks up to date! Using the innovative Bridge will save you time and money!

Collects data by devices sending their data via Wireless M-Bus.

Forwards data to your IoT cloud backend via LoRaWAN or SIGFOX1.

1: Sigfox version is available by Q2/2019.

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

STACKFORCE maintains the commonly best-known open source implementation of the LoRaWAN end node stack.

STACKFORCE is an experienced integrator of Sigfox.

What would be more obvious than to have STACKFORCE to combine Wireless M-Bus with LoRaWAN or Sigfox to create the WMBus-to-LPWAN Bridge?

Remote Management

Manage the WMBus-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.
