This is a work in progress to adapt Jean-Noël work to ESP8266 platform.
The framework used here is called Sming (a fork is available in my repo lists).
This framework makes it easy to develop alternatives firmwares in C++ for the ESP8266 and is compatible with most sensors libraries already available for the Arduino platform.
