FM232e - IoT LoRa Local Sensor - Electricity on meters

FM232e – IoT LoRa Local Sensor – Electricity

  • Plug & Play: non-intrusive optical reading technology, easy and quick to install, no electric contact
  • Universal: compatible with all electricity meters (with blinking LED or rotating disk)
  • Customized: multiple versions (1mn, 10mn, 15mn) adapted to you remote reading requirement
  • Accurate: power load curve in Watts, with 1-minute time step
  • Designed and manufactured in France


FM232e is an IoT LoRa sensor for electricity consumption monitoring with a 1-minute, 10-minutes or 15-minutes time step (option to be selected). The sensor consists of an optical reading head (to be installed on the existing main electricity meter) and a radio box (also including batteries). It connects locally to an F-Link micro-bridge (not included) through a specific local Lora radio protocol and sends the electricity curve at regular intervals.

The sensor only transmits messages to an F-Link micro-bridge (to be purchased separately). Up to 10 sensors can be registered on a single F-Link. The F-Link micro-bridge receives these radio messages and forwards to Fludia data collect server, by means of the existing Internet connection. The F-Link can connect to the existing Internet box (DHCP protocol) through one of these two means: Wifi (F-Link can be provided with the Wifi password with the help of a smartphone or a PC) or provided Ethernet cable.

Data can be retrieved from the data collect server either through the API or by connecting to the dashboard and manually downloading a file for a selected period of time. An FTP solution can also be provided.
