/*

* 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.
