Teleinfo to MQTT

Code is AS-IS without any warranty of any kind...

Hardware used :

  • Nodemcu 1.0 (but any ESP8266 breakout with enough pins should do)
  • Optocoupler SFH620A (but LTV-814 could be even better)
  • 2N7000 or BS170
  • 2 * 10k + 1 * 4.7k resistors


  • Version "Historique" (i.e. compatible with older meters) only for the moment
  • Version "Standard" (a.k.a new Linky version) to be written

The python OTA helper can be used to upgrade the software on the ESP8266
