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:
- Simple circuit to transform MBus levels to 3.3V serial
- Code to capture and analyze data from PC
- Code to capture and analyze data from Arduino
- Sample data from various meters
- Documentation on HAN / MBus / DLMS/COSEM
- Code to parse DLMS data into a structure
- Real schematics, including ESP8266
- PCB layout
- Arduino library
- Arduino sample sketch to read values and report to MQTT server
