The document discusses the integration of Internet of Things (IoT) technology for improved energy efficiency and the challenges associated with creating an open messaging layer to facilitate communication among diverse systems. It highlights the role of XMPP as a scalable, federated messaging network, emphasizing security, encryption, and the need for standardization through various XEPs. Joachim Lindborg, the document's author, advocates for open systems in IoT that enhance human interactions and proposes solutions for integrating multiple technologies related to smart home services.

The Big question nobody asked
BUT it’s XML !!???
• XEP 322 http://xmpp.org/extensions/xep-0322.html
• W3C binary compression EXI http://www.w3.org/TR/exi/
• Very efficient
• Small devices can do binary stanzas without building xml only C
stubs
• And still valid XML

About Joachim Lindborg
•Currently CTO of sust.se, I'm a technology enthusiast that
believe that IoT is really about human interaction with systems
adding value to life and that closed systems will die in favor for
open one.
•For the past 15 years I have been working with system
integration, especially at the intersection of energy and IT. I was
one of the founders of homesolutions.se a start-up company
integrating systems for supervision and maintenance of buildings.
•In the IT boom during the late 1990s I was employed by the
swedish Utility Vattenfall to develop solutions for the smart home.
It was an exciting time but it ended in disappointment. Now we
are back again and with Internet of Things and a more stable
technology I do believe that this time we will succeed. Right now I
am working with companies in home security, heating and air
conditioning, with energy companies and service developers in a
project integrating all these technologies with sound business
models for smart home services for energy control and efficiency.
