Project Brief The aim of this project is to control a number of household devices/appliances using Linux MCE and a Nokia 770 internet tablet. Research of various technologies and methods of home automation. Linux Media Centre Edition (MCE) to act as the central home automation software and control electronic devices in the home. Extend the system to enable control from an external remote control. Allow event handling within the system
3
Home system Core External Device Router Remote control Bluetooth connection Z-wave protocol
4
Comparison of Bluetooth, Zigbee & Z-wave Z-wave chosen - Mesh Network - Faster response times - Prolonged battery life Wireless communication protocol Operates at frequency of 868 MHz - simple control signals Two z-wave devices bought for this project.
5
Z-wave protocol System core Z-wave transmitter (USB dongle) Z-wave receiver (Lamp module) External device (Lamp) Z-wave USB Transmitter Connects with the Linux MCE Core Transmits/ receives control data to/from external device. Z-wave Lamp module Connects with the external device (Lamp) Transmits/receives control data to/from Core

Linux MCE Install stages AV wizard Launch Manager Home setup
7
Linux MCE Installed system Orbiter - Interface between the user and the Core Further options - changes to the system
8
Admin website Linux MCE Administration website Run by the Core. Complete control of system. Allows the user to alter the system. Setup set-up for unique home environment. Control of ALERTS Admin website access User access only - http://192.168.80.1/pluto-admin Core’s IP Address
9
Orbiter Nokia 770 as remote control of the Core Enabled device as remote on Admin website Applied Bug fixes to Nokia -WLAN memory corruption -Enabled swap MS true type core fonts Plutohome software install files Orbiter Log file - Monitors state of Orbiter
10
Modify system Toothpick Programmable in C. Not compatible with Linux MCE. Scenarios and Alerts -Scenarios Allows user to adjust system to suit various needs in various rooms -Alerts Activate when some criterion is met.
11
Conclusion Further Research Orbiter functioning on the Nokia 770 Modulation of Audio devices Home automation system Capabilities Alternate systems - Linux MCE favoured Cost Expensive. Z-wave devices.
