Switching Sonoff Basic and Sonoff S20 (Webserver or MQTT).

Copy sonoffSocket.ino into your Arduino-IDE folder. To use mqtt you have to install external library "PubSubClient". Change your SSID and WiFi-Key and activate MQTT if needed (choose a topic too). Connect Sonoff Basic or Sonoff S20 to your FTDI-Adapter and flash it using the Arduino-IDE.

The socket can be controlled by opening /ein (to activate) and /aus to deactivate. If MQTT is enabled, send 1 or 0 to your chosen topic (defined at the beginning).
