AMS <-> MQTT Bridge

Background

The purpose of this project is to collect information and build a simplified bridge for reading serial DLSM/M-bus information from electrical power meters (AMS), provided over the HAN port, and publishing to some IoT friendly target.

Components will be ESP8622, Arduino code, a (very simplified) M-bus <-> 3.3V serial interface

As a start, we should try to get information from the three types of AMS meters currently being installed in Norway. Some details about these are available here: NVE_Info_kunder_HANgrensesnitt.pdf

The project should include:

Circuit to read HAN from PC (via FTDI)

Circuit diagram

Circuit prototype

Breadboard

MQTT output
