FM432e – IoT electricity consumption sensor (LoRaWAN)

IoT LoRaWAN sensor for electricity consumption monitoring with a 1-minute 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).

The sensor 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.

• Universal: compatible with all electricity meters (with blinking LED or rotating disk)
• Plug & Play: easy and quick to install, no electric contact
• Accurate: power load curve in Watts, with 1-minute time step
• Designed and manufactured in France
