This is a replacement firmware for the ESP8266 based Sonoff devices mainly used for Blynk Server. Use it as a starting block for customizing your Sonoff.

It is based on tzapu/SonoffBoilerplate, but i changed some things and also it use BlynkSimpleEsp8266_WM to handle Wifi connection and Blynk server configurations parameters. It also handle correctly sensor hostname

Please note that is tested with ESP8266 Arduino Board version >= 2.7.4

I disabled OTA because SonOff basic has 1Mb Flash, too small to handle on the air updates.
