Romande Énergie — meter reading and data uplink to smart-me

WBox gateways read the M-Bus and Modbus meters across Romande Énergie’s installations and publish the data to the smart-me.com platform; remote access enables maintenance and metering diagnostics with no site visit.


The context

Romande Énergie is one of the leading energy players in French-speaking Switzerland: electricity generation and distribution, renewable energy and energy services. Tracking consumption and production relies on reading the meters spread across many sites and installations.

To make this data reliable and centralised, Romande Énergie relies on Weble gateways: they read the meters in the field and publish the readings to the smart-me platform, where they are visualised and used.

Reading M-Bus and Modbus meters

At each site, the WBox gateway polls the meters and measurement equipment over two complementary buses:

  • the M-Bus driver — energy, heat, water and gas meters, wired and wireless;
  • the Modbus driver (TCP/IP and RTU) — electricity meters, inverters, PLCs and technical equipment exposing a Modbus register map.

A single gateway aggregates both protocols with no intermediate hardware: it reads the meters at regular intervals, timestamps the values and formats them for uplink.


Data uplink to smart-me

The collected readings are published to the smart-me platform through the WBox’s dedicated driver. The gateway pushes the readings to smart-me.com, where Romande Énergie visualises consumption, follows load curves and uses the data for its business needs.

The smart-me connector is native: no extra application gateway to maintain between the field and the platform — the WBox speaks the smart-me protocol directly.


Remote access — maintenance and diagnostics

Weble’s remote-access service gives Romande Énergie secure access to every gateway, with no site visit. It is used for:

  • fleet maintenance — configuration, updates, adding meters;
  • metering diagnostics — remotely spot a meter that no longer responds, an M-Bus/Modbus bus fault or an inconsistent value, and fix it without a physical intervention.

For a distributed meter fleet, this remote diagnostics dramatically cuts travel and the time to resolve metering incidents.


The benefit

  • Two buses on one gateway: M-Bus and Modbus (TCP + RTU) read by the same device.
  • Native smart-me connection: direct uplink to the platform, no middleware.
  • Remote metering diagnostics: metering incidents are handled with no site visit.
  • Centralised operations: reliable, timestamped data for energy monitoring.
