* 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.
