Chapter 1. Introduction 2

Reuse: Already existing HA devices can be combined and reused. This reduces the installation

time as well as overall costs.

This work presents the integration of two exemplary HA systems, HomeEasy and Intertechno,

to an IE that uses middleware ROS. The implemented software consists of three parts: a driver

which programmatically abstracts the hardware to the middleware, a database container for storage

and mapping, and a graphical visualization program which provides a namespace service. As a

result, HA systems can be controlled via easily understandable ROS interfaces without the need

of detailed knowledge of communication parameters, such as protocol timings, package handling

and address mapping. The result of this work has been tested in an oﬃce and home scenario and

evaluated by various benchmarks.

The challenge faced in this project was to adapt the software to the special characteristics of

each supported HA system in order to allow as many systems as possible to be contolled without

compromising special functions. Since these systems may diﬀer generally, diﬃculties may arise

when developing a storage class and functions for interconnection.

1.2. Outline

Chapter 2 covers the basics for all software and hardware parts of this work and presents other

projects with similar goals to provide an overview of current research projects.

Chapter 3 deals with the concepts and ideas of the process of integrating HA in IE. The software

and hardware used are presented and the abstraction chain and storage class are discussed in more

detail. Finally, a requirement analysis outlines the demands for the following software layers.

Chapter 4 deals with the implementation of the concepts as presented in the chapter 3. It consists

of two parts: Firstly, the used gateway and the changes that were undertaken to adapt it to this

work are introduced. Secondly, the diﬀerent software parts and their interactions are examined.

Chapter 5 deals with the evaluation of the complete system. Two test scenarios are described,

one oﬃce and one home environment as well as various simulations for testing the performance

of the system.

Chapter 6 summarises this paper.
