Arduino-teleinfo

Teleinfo library for arduino

For french teleinfo system (Enedis, ex ERDF). Your will need a very simple electonic circuit based on an optocoupler (SFH620A or SFH6206) and 2 resistors. Many sites explain how to build it (on some sell it).

Counter               _____________       /-------R2---- 3.3V
   I1 -------R1-----1| optocoupler |4----/-------------- RX    Arduino
   I2---------------2|_____________|3------------------- GND
                     
R1=1.2k
R2=10k

Warning

This library requires "a lot" of memory (about 600 bytes) and may be configured in Teleinfo.h for bigger frame size (other contracts). Nano and Uno has 2kB of memory. Arduino Mega 2560 has 8kB. Note: Arduino mega that has several hardware serial and bigger memory, it's nice for this usage.

Important, initialization

In setup, you have to call:

serial.begin(1200);

Initialization for software serial:

#include <SoftwareSerial.h>
SoftwareSerial serial(2,3);
TeleInfo teleinfo(&serial);

Initialization for hardware serial:

TeleInfo teleinfo(&Serial);

Example:

#include <TeleInfo.h>
#include <SoftwareSerial.h>


const int rxPin = 2;
const int txPin = 3;

SoftwareSerial softSerial(rxPin,txPin);
TeleInfo teleinfo(&softSerial);
//TeleInfo teleinfo(&Serial2);

void setup(){
  Serial.begin(9600);
  softSerial.begin(1200);
  //Serial2.begin(1200);
  teleinfo.begin();
  //teleinfo.setDebug(true);
}
void loop(){
  teleinfo.process();
  if(teleinfo.available()){
    Serial.println("--- tele info available --- ");
    teleinfo.printAllToSerial();
    Serial.println("------ ");
    
    //const char *periodTarif = teleinfo.getStringVal("PTECZ");
    //Serial.print("Period Tarifaire = ");
    //periodTarif == NULL ? Serial.println("unknown") : Serial.println(periodTarif);
    
    const char *opTarif = teleinfo.getStringVal("OPTARIF");
    Serial.print("Option Tarifaire = ");
    opTarif == NULL ? Serial.println("unknown") : Serial.println(opTarif);
    
    long power = teleinfo.getLongVal("PAPP");
    Serial.print("Power = ");
    power < 0 ? Serial.println("unknown") : Serial.println(power);
    
    teleinfo.resetAvailable();
  }    
}
