Chapter 4: Demonstration and Test
Functions
This chap ter will introduce to the S mart Home Automation demo application
and how to use the example applications contained in the system to
implement functionality tests of the EDM6070, as we ll as a demonstr ation of
the LinuxQT graphics interface.
4.1 Smart Home Automation Demo
A Smart Home System demo application has been provided with the
EDM6070. This d emo applica tion enables EDM developers to qu ickly and
easily jumpstart their embedded Linux application development — without
first having to set up their development environment. Smart Home
automati on demo fe atures a Q T GUI appl ication with several custo m widgets,
including:
Climate Control
Light control
Thermostat control

Video player
4.1.1 Demo Features
This demo showcases the control of various house functions including
heating, lighting, security and a media player. The major functions are
expounde d upon be lo w:
4.1.1.1 Climate Control
This ap plication allo ws the user to control the tem perature an d humidity
throughout the house on a room by room basis. There is also a display
indicating the current weather which can be activated to display extra
information:

Pulse-doppler radar weather display
The weather information is updated via the internet and as such the
EDM6070 requires an internet connection in order to provide this
functionality
4.1.1.2 Lighting Control

The ligh tin g a p plicatio n a llo w s th e us er to set th e l ig h t levels in ea c h r o om
independently. The application emulates a standard dimmer switch making
the software both intuitive and user friendly
4.1.1.3 Security
The security applicati on allows the EDM6 070 to connect to cameras and door
locks at any user defined entrance. This allows the user to monitor the
entrance and either allow or deny access to the p ro perty
