* 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.

* REVISION HISTORY
|
|
* Version 1.0 - Henrik Ekblad
|
|
*
|
|
* DESCRIPTION
|
|
* Example sketch for a "light switch" where you can control light or something
|
|
* else from both HA controller and a local physical button
|
|
* (connected between digital pin 3 and GND).
|
|
* This node also works as a repeader for other nodes
