 # Principle of operation
 The ESP8266 is maintained in permanent Deep Sleep state (do not connect GPIO16 to RESET).
 A pulse is generated on RESET whenever the door opens and the switch closes, resulting in
 waking up the ESP. Once awaken, the ESP8266 connects to the Wifi, the MQTT server and then
 publish on a given topic before entering in Deep Sleep.
