+ *******************************
+ *
+ * REVISION HISTORY
+ * Version 1.0 - Henrik EKblad
+ * Contribution by a-lurker and Anticimex, 
+ * Contribution by Norbert Truchsess <norbert.truchsess@t-online.de>
+ * Contribution by Ivo Pullens (ESP8266 support)
+ * 
+ * DESCRIPTION
+ * The EthernetGateway sends data received from sensors to the WiFi link. 
+ * The gateway also accepts input on ethernet interface, which is then sent out to the radio network.
+ *
+ * VERA CONFIGURATION:
+ * Enter "ip-number:port" in the ip-field of the Arduino GW device. This will temporarily override any serial configuration for the Vera plugin. 
+ * E.g. If you want to use the defualt values in this sketch enter: 192.168.178.66:5003
+ *
+ * LED purposes:
+ * - To use the feature, uncomment WITH_LEDS_BLINKING in MyConfig.h
+ * - RX (green) - blink fast on radio message recieved. In inclusion mode will blink fast only on presentation recieved
+ * - TX (yellow) - blink fast on radio message transmitted. In inclusion mode will blink slowly
+ * - ERR (red) - fast blink on error during transmission error or recieve crc error  
+ * 
+ * See http://www.mysensors.org/build/ethernet_gateway for wiring instructions.
+ * The ESP8266 however requires different wiring:
+ * nRF24L01+  ESP8266
+ * VCC        VCC
+ * CE         GPIO4          
+ * CSN/CS     GPIO15
+ * SCK        GPIO14
+ * MISO       GPIO12
+ * MOSI       GPIO13
+ *            
+ * Not all ESP8266 modules have all pins available on their external interface.
+ * This code has been tested on an ESP-12 module.
+ * The ESP8266 requires a certain pin configuration to download code, and another one to run code:
+ * - Connect REST (reset) via 10K pullup resistor to VCC, and via switch to GND ('reset switch')
+ * - Connect GPIO15 via 10K pulldown resistor to GND
+ * - Connect CH_PD via 10K resistor to VCC
+ * - Connect GPIO2 via 10K resistor to VCC
+ * - Connect GPIO0 via 10K resistor to VCC, and via switch to GND ('bootload switch')
+ * 
+  * Inclusion mode button:
+ * - Connect GPIO5 via switch to GND ('inclusion switch')
+ * 
+ * Hardware SHA204 signing is currently not supported!
+ *
+ * Make sure to fill in your ssid and WiFi password below for ssid & pass.
