Overview

Objectives

• To control the environment at home, in order to provide the necessary comfort, security and safety

• To offer remote access to home appliances• To monitor home status anytime, anywhere• To increase confidence and self-esteem of the

elderly or people with physical disabilities inside the house

• To reduce in-house physical mobility for people with physical disabilities

• To provide to elderly people’s caregivers (i.e. neighbors, family relatives) the opportunity to monitor their home environment

Actuators

•Door ▫Open▫Close▫Lock

•Devices ▫Switch on▫Switch off

•Light ▫Increase brightness▫Decrease brightness

Sensors

Infrastructure

How it works (1/2)

• A specific Bus-Adapter, the so-called CUL-Stick, provides a bridge to all communication protocols in the frequency band of 868MHz. The CUL-Stick is connected by USB to the Domotic server.

• The assignment of domotic devices to the Domotic server is realized by the so-called Learning process.

• To provide web-services for every device of the domotic network, the Domotic server has to “know” each device and its functionalities.

• During the installation process, a new device is assigned to the Domotic server by the installer. This is done by creating a virtual representation of the device, existing as software structure inside the Domotic server.

How it works (2/2)• All web services will affect the virtual representation of

the device, and the Domotic server will forward status change automatically to the “real” device (placeholder mechanism). Vice-versa, status changes of the real device will be mapped to the virtual device.

• During the installation process, a technician switches a domotic device to a “learning mode” and uses a web interface (next slide), provided by the Domotic server, to assign the device.

• The Domotic server creates an abstraction instance for the device type. Accordingly, the Domotic server creates a unique address and sends it with a command to the device, which is in the learning mode.

• After the learning process, the device is “known” by the Domotic server, and it can be controlled by web-services.
