/* initial z wave install */
* if not checked, use habmin to unpair device, hit the ''A'' button again to complete un-pair.
* discover the lock again, check that ''using security'' is checked
* make sure the pantry outlet switch (z-wave device) is plugged in, it serves as a bridge to the door lock, since that cannot be reached from the Z-Wave serial stick directly
lots of good info on [http://www.cd-jackson.com/index.php/openhab/5-zwave-debugging-openhab chris jackson's site]
