Introduction

New technologies provide increased comfort and quality in all areas of our lives. With home

and building automation, simple things like automatically raising the shutters in the morning as

well as more complex environments can be created. Particularly noteworthy is Ambient Assisted

Living (AAL), which enables the elderly and disadvantaged people to live independently. Many

studies have shown that being able to continue living at home with assistive technology, is in

most cases cheaper, more eﬀective and more beneﬁcial for the individual, than living in a care

or nursing home [1]. In addition, the rapid development of technologies in the ﬁeld of computer

and communication has led to the development of smaller, more powerful and less expensive

devices. These devices will become more widespread and the interface man - technology will

become increasingly blurred. Weiser predicted this in 1991 [2] and called this type of computing

"Umbiquitous Computing". Umbiquitous Computing means that technology becomes absorbed

into everyday objects, enabling the user to use the system without explicitly being aware of it.

Unfortunately, in most home and building automation systems this development has been slow

due to a lack of standard communication interfaces.

1.1. Motivation, Goals and possible Challenges

This work provides a uniﬁed framework of Home Automation (HA) and Intelligent Environments

(IE), so that both systems can connect and beneﬁt from each other. There are many advantages

for using HA components in IE:

Low-cost: Simple HA systems are usually produced in large quantities and are therefore usu-

ally cheaper than dedicated hardware, commonly used in IE. Consequently, there is a cost

advantage, when using HA for simple tasks such as switching electrical appliances on or oﬀ.

Intelligence: In contrast to HA, an IE can learn from user and environmental inputs, enabling

integration of HA in more complex systems.
