Arduino / LoRaWan PiT Info

This project has been made to report the PIT Info (Electrical Consumption like for linky but much more) over LoRaWan. The project is basic only works for "Base" Information corresponding to the overall energy counter. It's going to be hard to extend it on the tiny hardware used for running it.

Hardware

• Arduino LoRaRadio Node board
• PiTIUnfo board from Charles (ch2i)
• some wire
• 2x 1/2 AA 3,6V batteries

Mounting

• The Pit Board is connected with TX to D4, VCC to D3, GND to GND

Data format

Base is the global energy counter Value Delta is the difference between two tranmissions (keep in mind that some packets will be lost)

byte	means
0	base & 0xFF000000
1	base & 0x00FF0000
2	base & 0x0000FF00
3	base & 0x000000FF
4	delta & 0x00FF0000
5	delta & 0x0000FF00
6	delta & 0x000000FF

Helium decoder

function Decoder(bytes, port, uplink_info) {
  decoded = {
     base : (bytes[0] << 24) + (bytes[1] << 16) + (bytes[2] << 8) + bytes[3],
     delta : (bytes[4] << 16) + (bytes[5] << 8) + bytes[6] 
  };

  return decoded;
}
