MOBILE KNX
DESIGN, DEVELOPMENT AND ANALYSIS OF A
MOBILE NETWORK BRIDGE FOR DOMOTIC
SYSTEMS

2. Background
¨ Increase of energy consumption
¨ Need to easily control the electrical and
mechanical devices
Green Homes Building Automation
Systems

3. Background
¨ Is it possible to merge these concepts in order to
create an easy-to-use system? And how?
¨ Why don’t use mobile technologies to control a
house?

4. Background
¨ Building Automation Systems
¤ BACnet
¤ LonWorks
¤ EIB/KNX

5. Background
¨ KNX network controlled by mobile device
¤ KNX provides the basic infrastructure for a BAS
¤ Mobile application gives access to KNX
¨ Are there already solutions in the current market?
¨ Are they improvable?

10. Implementation

11. Implementation
¨ BRIDGE CORE
¤ Gets input a configuration file
¤ Analyzes a configuration file
¤ Creates connection to a KNX network
¤ Sends messages to a KNX network
¤ Receives messages from a KNX network
CALIMERO

12. Implementation
¨ BRIDGE
¤ Creates a point of connection between:
n BridgeCore
n Environment that surrounds the BridgeCore
¤ Receives HTTP requests
¤ Replies to HTTP requests
TOMCAT

13. Implementation
¨ MOBILE DEVICE application
¤ Gets configuration data from the Bridge
¤ Renders configuration data
¤ Sends HTTP requests
¤ Receives HTTP replies
PHONEGAP

14. Testing
¨ Three main functions
¤ Reading configuration data
¤ Reading KNX devices status
¤ Writing KNX devices status
System reacts in the right manner

15. Testing
¨ Mobile devices
¤ HTTP requests and replies through ad-hoc web pages
¨ Measure time of execution for each request
New set of real data

16. Testing
¨ Mixing system features
¤ Reading configuration
¤ Reading value
¤ Writing value

17. Testing
¨ Most of the request has a
response time less than the
average time 73.63ms

18. Conclusions
¨ KNX idea and structure are easy to understand
¨ ETS is an easy-to-use configuration tool
¨ The Bridge permits to skip one configuration phase
¤ Good response time
The system works and can be easily expanded
Improved the automation part of the current systems

19. My experience abroad
POSITIVE
þ New country
þ New culture
þ New “human connections”
þ Improved my english
NEGATIVE
þ Absence of teamwork
