* The MySensors Arduino library handles the wireless radio link and protocol
* between your home built sensors/actuators and HA controller of choice.
* The sensors forms a self healing radio network with optional repeaters. Each
* repeater and gateway builds a routing tables in EEPROM which keeps track of the
* network topology allowing messages to be routed to nodes.

* The EthernetGateway sends data received from sensors to the ethernet link.
* The gateway also accepts input on ethernet interface, which is then sent out to the radio network.
* The GW code is designed for Arduino 328p / 16MHz. ATmega168 does not have enough memory to run this program.
* LED purposes:
* - To use the feature, uncomment MY_DEFAULT_xxx_LED_PIN in the sketch below
* - 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 for wiring instructions.
