Lately I discovered IoT and Clayster for my self.
One good way to learn new things is to resolve some problem using new technology. So I thought to build system detects is somebody is behind in my display. And I’d like to detect it over XMPP.

Connected with RP using schema
And I can read readings over XMPP
And finally the most coolest thing – HomeArena by Clayster
