This document proposes a home automation remote control system using different network technologies like X-10, GSM, and Internet Protocol. It would allow control of devices from anywhere for convenience, security, and accessibility. The proposed system diagram shows how these technologies integrate and communicate. Standards are important for interoperability between control points, IP devices, and middleware that translates between the different technologies. User interfaces must be intuitive and provide system status. Remote control helps make homes intelligent and automated for all.

 Conclusion

3. OBJECTIVES
 Develop a Home Automation Remote System
 Use different inner and outer network technologies
 Use devices that are easy to install
 Use low-price materials and devices
 Make it suitable for inexperienced users or even disabled people
 Make it scalable for further add-ons
 Manage multiple control points
 Encourage standardization

5. WHY REMOTE CONTROL?
 Enables control from almost anywhere (more comfortable)
 Instant alerts greatly increase security
 Backup emergency control
 Optimal for people with reduced mobility
 It can be combined with local control to give higher flexibility.
 The network hierarchy has been rapidly moving lower in the
chain towards smaller and more personal devices (Canosa, 2001)

7. X-10
– Technique “Power Line Carrier”
– Frame sent two times
– Noise filter / Phase coupler
– Up to 256 controlled devices

– AT / AT+ commands
– Serial connection
– SMS
– MMS
– Dials

9. INTERNET PROTOCOL

– Control Points
– IP devices
 IP cameras
– Web browsers
– XML
– Siemens UPnP Stack
 Addressing
 Discovery (SSDP)

10. INTERFACES & MIDDLEWARE
 Middleware
– Standard compatible
– Link technologies (translation)
– Robust
 User interfaces (Local & Remote)
– Must follow Heuristic Evaluation (Molich and Nielsen 1990)
– High usability
 Good visibility of system status
 Match between system and real world
– Error prevention (minimize error messages)
– Aesthetic and minimalist
– Help

12. Conclusion
 The E-home is coming quickly
 Standards are not completely established
 Remote Control is necessary for certain purposes
 Developing low-price systems will accelerate the
process of turning our homes intelligent
 The price of the “intelligence” in a house in
comparison with its “body”, is insignificant
