+ * 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 - January 30, 2015 - Developed by GizMoCuz (Domoticz)
+ *
+ * DESCRIPTION
+ * This sketch provides an example how to implement a Dimmable Light
+ * It is pure virtual and it logs messages to the serial output
+ * It can be used as a base sketch for actual hardware.
+ * Stores the last light state and level in eeprom.
