Various code projects to help debug and build the final system Various code projects to help debug and build the final system
### HanDebugger ### HanDebugger (C# console)
A very simplified c# console application to read serial data directly from the HAN bus, using the HAN-FTDI circuit and a FTDI device (USB serial port). The application will simply use the right serial setup (2400 baud, 8E1) to set up a connection and continously read incoming data. The received data is split on the package start and -end flags (0x7E) and output to console.

### ESPDebugger (Arduino sketch on ESP8266)
Very similar to the HanDebugger, simply reading the HAN data and outputting the same data to the Serial1 port, HEX-formatted and splitted by lines on start and -end flags.

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. 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 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](Documentation/NVE_Info_kunder_HANgrensesnitt.pdf)
The project should include: The project should include:
* schematics, possibly PCB - [x] [Simple circuit to transform MBus levels to 3.3V serial](/Electrical/Simple%20HAN%20to%20FTDI%20Circuit.jpg)
* documentation, samples - [x] [Code to capture and analyze data from PC](/Code/HanDebugger)
* arduino library - [x] [Code to capture and analyze data from Arduino](/Code/ESPDebugger)
* ad-hoc testing code - [x] [Sample data from various meters](/Samples)
- [x] [Documentation on HAN / MBus / DLMS/COSEM](/Documentation)
- [ ] Code to parse DLMS data into a structure
- [ ] Real schematics, including ESP8266, possibly PCB
- [ ] Arduino library
- [ ] Arduino sample sketch to read values and report to MQTT server
