For anyone that is interested,
I got to talk to one of the Sr. Engineers for Smartenit that let me know that DBus is no longer a supported interfacing technology for the Raspberry Pi ZBP server.
He directed me to use the REST API instead. I am glad that he did because it looks great! So much easier to access my devices then the XML way. Here is a link to the REST API documentation: http://wiki.smartenit.com/rest/
