FM432e - IoT Electrical Consumption Sensor (LoRaWAN)

**FM432e** is an IoT sensor for monitoring electricity consumption (electrical power) in all types of buildings. It is easy to install on the existing main electricity meter. It connects to LoRaWAN communication networks so that the power curve can be collected at regular intervals. This professional solution is extremely suitable for remote monitoring of small and medium-sized buildings.

**LoRaWAN IoT sensor** for monitoring electricity consumption with a time step of 1 minute or 15 minutes (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 self-decoded (payload format described) or sent to the Fludia server to be decoded and retrieved via an API.

- **Universal**: compatible with all electricity meters (with flashing LED or rotating disk).
- **Plug & Play**: quick and easy to install, without electrical contact
- **Accurate**: power load curve in Watts, with a 1-minute time step
- Designed and manufactured in France
