2.2. Home Automation

Home Automation (HA) describes the functionality provided by control systems to operate, super-

vise and regulate processes in private homes. It is a part of building automation with residential

extension to match the needs of the home and its residents. HA aims to provide improved conve-

nience, comfort, energy eﬃciency and security, through the provision of diﬀerent services, such as

intelligent automatic controls and graphical user interfaces. To gain the consumer’s acceptance,

certain requirements need to be met:

Easy to use: Interfaces should be user-friendly to lower the usage barriers and allow the system

to be integrated eﬀortlessly in everyday life. Appealing designs will encourage the user to

engage with the system [7].

Future-proof: Systems have to be well-proven and future-proof to sustain the long life of a

building, which is several times as long as the innovation cycle of the technologies itself.

In addition, wired systems usually cannot be replaced easily and must therefore be reliable

and maintainable. Consequently, spare parts or at least compatible replacements must be

available for a long period of time.

Security: Attacks, vandalism or simple interference between two systems can cause problems. To

protect the users and their home from damage, security considerations are necessary.

In building automation, the maintenance and compatibility between the systems is desirable,

whereas the following considerations can play an important role for HA:

Easy to install: No qualiﬁed personnel should be needed to conﬁgure and install the system.

This will avoid extra costs and increase popularity with the customers.

Flexibility: Interior decorations will change every now and then and new appliances will be in-

stalled, removed or exchanged. Furthermore, many users will buy their automation compo-

nents step by step. Therefore, systems have to be scalable and new components must be

easy to integrate.

Easy to purchase: As HA components are situated in numerous locations in the building, entities

must be low-priced, to be aﬀordable for the user. This means that inexpensive technologies

must be used.

2.2.1. Possibilities

Building automation is primarily chosen to enable central management and administration of an

environment. Existing solutions, such as KNX, only provide rough support for modern services,
