► Motivation - The Internet of Things (IoT) and KNX
The 'Internet of Things' in home and building automation (and in particular KNX)
requires co-operation of two worlds.
Internet world
KNX world
Standards Objects
TCP, UDP, HTTP, HTML,
XML, JSON,.., various
standards by the W3C
consortium
KNX Standard,
Comprehensive
Handbook: Datapoint
types, Telegram
structure, ..
Text and images, URLs,
encodings,..
Wide range of KNX devices,
application programs,
communication objects, KNX

properties, ..
What is the common language?

► Motivation - The Internet of Things (IoT) and KNX
The „common language“ between the Internet world and the KNX world requires an
agreement about:
WHAT to talk about.
An intuitive set of objects, which do not require deep KNX knowledge!
More about the 'meaning' of objects, less about KNX internal communication.
HOW to talk.
A data protocol, which is suitable for the Internet.
The KNX Web services standard enables KNX for fast growing business models in the
internet, which rely on easy and standardized access to buildings and homes.
.. and other tools as well can benefit from
easier access and easier configuration ..

► Principal components – clients' perspective
From a KNX Web service client's perspective (remotely over IP) :
Information system of meaningful objects in the KNX installation.
This information system includes datapoints, room topology, functionalities,
custom views and tags provide extended navigation capabilities.
RESTful (REpresentational State Transfer) web interface to read and write
values. KNX Web services support oBIX – using oBIX can be as easy as
reading and writing XML files.
.. and more possibilities presented at the Light+Building
2016

► Principal components – system integrators' perspective
From a system integrator's perspective (maintaining the KNX site) :
Add-in to the ETS Tool (the one configuration
tool for KNX) allows to create a
'KNX tagged information model'
for an ETS KNX project.
Project information can be
shaped for the KNX Web services.
Adding custom views and tags to the information
model is like putting up street-signs for
interesting locations.
