FM432ir - IoT LoRaWAN Sensor - Electricity on meters

FM432ir – IoT LoRaWAN Sensor – Electricity

  • Plug & Play: non-intrusive monitoring solution, easy and quick to install, no electric contact
  • Universal: compatible with all electricity meters (with infrared port or with rotating disk)
  • Accurate: power load curve in Watts, with 1-minute time step
  • Communication: ensured connectivity to all LoRaWAN 1.0 networks
  • Designed and manufactured in France


Infrared IoT LoRaWAN sensor for electricity consumption monitoring with a 1-minute or 15-minutes time step (depending on the chosen option). The sensor consists of an optical reading head (to be installed on the existing main electricity meter) and a radio box (also including batteries). The FM432ir is dedicated to reading information delivered by an infrared communication port and is compatible with mME meters in Germany.

It can be connected to a LoRaWAN network. Data can be decoded autonomously (payload format described) or sent to the Fludia server to be decoded and retrieved through an API.

It is easy to install on the existing main electricity meter. This professional solution is extremely adequate for the remote monitoring of small and medium buildings.
