PRODUCT BRIEF
USER GUIDE

Description

The FM442ir is a plug-and-play IoT sensor designed for monitoring electricity consumption in all types of buildings. The FM432ir is dedicated to reading information delivered by an infrared communication port and is compatible with mME meters in Germany.

The optical head can be quickly attached to the main electricity meter or a submeter, and the NB-IoT/LTE-M modem connects through standard cellular networks.

Measurement data is transmitted to an MQTT broker and can be retrieved by any EMS (Energy Management System).
