USER GUIDE

Description

FM232ir is an IoT sensor for monitoring the electricity consumption (electric power) of all types of buildings. It has been specially designed for meters with infrared communication ports (mME German meters with SML protocol), but can also be used with old Ferraris meters. It is easy to install on the existing main electricity meter. The sensor consists of an optical reading head and a radio box (also including batteries) and is available with a 1-minute or 15-minutes time step (option to be selected).

It connects locally to an F-Link micro-bridge (not included) through a specific local Lora radio protocol and sends the electricity curve at regular intervals. The sensor only transmits messages to an F-Link micro-bridge (to be purchased separately). Up to 10 sensors can be registered on a single F-Link. The F-Link micro-bridge receives these radio messages and forwards to Fludia data collect server, by means of the existing Internet connection. The F-Link can connect to the existing Internet box (DHCP protocol) through one of these two means: Wifi (F-Link can be provided with the Wifi password with the help of a smartphone or a PC) or provided Ethernet cable.

Data can be retrieved from the data collect server either through the API or by connecting to the dashboard and manually downloading a file for a selected period of time. An FTP solution can also be provided.
