Introduction

Home Automation

A technique to use computer/smartphone and Information Technology in

controlling Home appliances and Home features

‘Smart Home’

Appliances (lighting, heating, air conditioning, TVs, Computers, Audio-Video

systems, Security and camera systems) are capable of communicating with

one another

Controlled remotely by a time schedule from any room or from any location

in the world by phone or internet.

3

Objectives of Smart HomesProvide improved convenience, comfort, energy efficiency and security.

Promoting even utilization of electricity

Minimizing energy loss during power consumption.

Increase quality of living, especially of the elderly and the disabled.

Demand Response Management

Examples of Smart home applications:Automate chores:

• watering lawns

• controlling lights and appliances such as electric water heater.

Motion sensors:

• turn on floodlights and cameras outside home

• turn on lights indoors as you walk from room to room

• create an automatic doorbell

Water sensors:

• to inform of leaking plumbing, while you’re at home or away for the day or on vacation

Remotely adjust thermostat

• thermostat adapts the room temperature efficiently, e.g., by auto-scheduling heating according to arrival and departure times and by detecting when the users are away

Home surveillance system

• via webcams and the Internet

Set up computer to alert about storms

• notify by e-mailing or calling cell phone or pager.

Security

• monitoring doors and windows fire, smoke, water

Software : Linux (as a server)

Linux is an open source and free OS. We use Linux OS as a server.We can customize linux kernel and make work for new devices.

Mister House(Web Interface)

MH is written entirely in Perl. It has a rather strange Object Orientedmethod of coding because MH writes some of it's Perl code atstartup. Plenty of examples exist. Mail lists are very friendly andsupportive.

Heyu (Control X10 Devive )

Heyu is a command-line-based program that you can use to controlhome’s lights and appliances via X10 devices. It’s written in the Ccomputer language. It can also be used to store a schedule ofevents which it can execute even when not connected to thecomputer. 12

Integration of Smart Home with Smart Grid

Emerging feature : Conservation of energy resources

Industrial alliances : AMI vendors and Zigbee Alliance

Promotion of demand response functionality

Integration of low power wireless sensors and control

network technology into Smart Meter

Acting as communicating gateway to home devices

Devices enable calculation of and log usage by all

connected devices

Provides real time energy usage information and hence

support dynamic pricing

17

18Fig 5. Integration with the grid

Consequence:

Change in energy consumption behaviour: shifting of

loads on the basis of costs and load curves.

This is known as “Demand Response”.

DR is defined as changes in electric usage by end users

◦ Change in price of electricity over time

◦ Incentive payments designed to induce lower electricity use at

times of high wholesale market prices

◦ When system reliability is jeopardised.

Challenges :

Achieve the harmonization of the data model

Provide abstraction upon the network protocol

Guarantee a suitable connection to the real-time middleware

21

Energy awareness through social

comparisons Assimilation of energy consumption in social networking

sites.

Comparison of energy usage.

Awareness of technologies employed for optimal energy

consumption.

Awareness of importance of saving energy.

‘Social Electricity’.
