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 SIGFOX.

Fact 1: STACKFORCE owns the famous, well-known and well-proven hardware independent Wireless M-Bus Stack.

Fact 2: STACKFORCE maintains the commonly best-known open source implementation of the LoRaWAN end node stack.

Fact 3: STACKFORCE is an experienced integrator of Sigfox.

Conclusion: What would be more obvious than STACKFORCE is the ideal candidate to combine Wireless M-Bus with LPWAN stacks 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.

Scan mode

Use the scan mode to detect all available Wireless M-Bus devices that are in range of the WMBus-to-LPWAN Bridge and can be collected respective forwarded to your IoT Cloud Backend.

Receive a list of all devices at your IoT Cloud Backend to choose the devices to be considered and configure the bridge accordingly.

All done remotely, from within your IoT Cloud Backend.
