Need to connect M-Bus and LoRaWAN? The Weble WBox routes M-Bus LoRaWAN natively: one gateway speaks both protocols and maps data points in real time — no PC, no middleware, no cloud dependency.

The protocols

M-Bus

M-Bus reads heat, water, gas and electricity meters over a dedicated 2-wire bus.

M-Bus driver →

LoRaWAN

LoRaWAN carries data from battery-powered sensors over several kilometres with very low power.

LoRaWAN driver →

Example deployment

Typical scenario Wired + wireless metering A campus reads its heat and water meters over M-Bus, but outlying buildings and retrofit points are covered by LoRaWAN sensors and radio sub-meters. The WBox collects both on one device and presents a single, unified set of metering points — wired M-Bus and long-range LoRaWAN side by side — for the energy platform. Technical documentation →

How the WBox bridges M-Bus and LoRaWAN

On the WBox you enable the M-Bus driver and the LoRaWAN driver, then map each point: a value read on the M-Bus side — the metering bus — is exposed on the LoRaWAN side — long-range, low-power wireless — and vice-versa. Conversion, scaling and logic run on the gateway itself.

Capacity & limits

  • M-Bus — M-Bus drives up to 190 metering slaves through a Weble level converter (250 per the standard).
  • LoRaWAN — LoRaWAN scales with the network server; device count is bounded by gateway coverage and airtime, not by the WBox.

On the WBox, a driver licence enables the whole protocol — there is no artificial per-point tier to unlock. Capacity scales with the gateway model, from the compact S103 to the E413: you are bounded by the field bus, not by your licence.

Frequently asked questions

How do I connect M-Bus and LoRaWAN?

M-Bus is the metering bus and LoRaWAN is long-range, low-power wireless. A single WBox gateway runs the M-Bus and LoRaWAN drivers, speaks both protocols at once and maps the data points between them — no PC, no middleware, no cloud dependency.

Does data flow both ways?

M-Bus is metering, so that side is read-only: the WBox reads the meters and exposes the readings on the LoRaWAN side. On the same gateway it can additionally route writable protocols if the project needs it.

Do I need a PC, a PLC or proprietary hardware?

No. The M-Bus and LoRaWAN drivers are licence-activated on one WBox — no gateway PC, no intermediate PLC and no proprietary hardware.

Which WBox model do I need?

Any WBox with the M-Bus and LoRaWAN driver licences. The online configurator recommends the right model from your interfaces and point count.
