Energy saving pack

Energy saving Pack – IoT LoRa Local Sensor – Electricity

  • Plug & Play: non-intrusive technology, easy and quick to install
  • Universal: compatible with all electricity meters (with blinking LED or rotating disk)
  • Connected: Long Range radio between the FM232e sensor and an F-Link
  • Accurate: power load curve in Watts, 1-minute time step
  • Designed and manufactured in France


The Energy Saving Pack is a Plug&Play solution for collecting and monitoring electricity consumption. Dedicated to small buildings, this solution includes an FM232e sensor and an F-link mini-bridge. Measurement time step is 1 minute.

The FM232 sensor sends radio frames at regular intervals (every 20 minutes) including several successive measurement values and thus makes it possible to monitor its electricity consumption as closely as possible. The F-Link mini-bridge receives these messages and forwards them to the Fludia data collect server, through the existing Internet access.

An ideal solution for office companies, shops and municipalities who wish to monitor their consumption directly and quickly implement energy sobriety actions.
