To connect BrewManiac with ESP8266 and make it a WiFi-enabled device.
The build environment uses ESP8266/Arduino. A few additional libraries is necessary: WiFiManager https://github.com/tzapu/WiFiManager ESPAsyncTCP https://github.com/me-no-dev/ESPAsyncTCP ESPAsyncWebServer https://github.com/me-no-dev/ESPAsyncWebServer ESP8266HTTPUpdateServer (newer version is needed.) https://github.com/esp8266/Arduino/tree/master/libraries/ESP8266HTTPUpdateServer
To configurate the hardware settings, mainly the Serial port, open config.h and change the #define's.
