sketch_jul16a_-_Brinks_WTW.ino

/**
 * Last Modified 27-09-2017 - S.Incze
 * Reason: Due due NO / NC of Brinks installation
 * Brinks Switches due to a link between 2 points. If Normally Closed is Used and Mysensors disconnects the WTW turns on.
 * That is why Layout changed to connect brinks to NO pins.
 * 
 * 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.
