Reference of the Modbus transmitter for Energy Meter




Applications of the transmitter


Compatible with energy meters with a Modbus interface, this meter transmitter reference allows the automated reading of the meter to which it is connected (Modbus register reading) and the continuous operation of this data without any manual intervention.

High-precision data is retrieved and transmitted to the Sigfox Cloud at a flexible frequency, configured in advance.

This transmitter will quickly and economically transform your conventional energy meter into a smart meter.


Continuous monitoring of your energy consumption will allow you to :

  • drive your energy consumption
  • monitor your equipment and detect any malfunction
  • prevent over-consumption


Optimising management of your consumption will allow you to achieve significant cost savings regardless of the size of your company and sector of activity.

This transmitter is mains powered.

It is also available in RS485, allowing the reading of Modbus registers of multiple counters – up to 10 supported meters.
