this print for content only—size & color not accurate 7.5 x 9.25 spine = x.xxx" xxx page count Goodwin Smart with Linux Home Automation   CYAN   MAGENTA   YELLOW   BLACK   PANTONE 123 C Companion eBook Available BOOKS FOR PROFESSIONALS BY PROFESSIONALS ® Smart Home Automation with Linux Dear Reader, With this book you will turn your house into a smart and automated home. You will learn how to put together all the hardware and software needed for home automation, to control appliances such as your teakettle, CCTV, light switches, and TV. You’ll be taught about the devices you can build, adapt, or hack yourself from existing technology to accomplish these goals. In Smart Home Automation with Linux, you’ll discover the scope and possi- bilities involved in creating a practical digital lifestyle. In the realm of media and media control, for instance, you’ll learn how you can read TV schedules digitally and use them to program video remotely through e-mail, SMS, or a web page. You’ll also learn the techniques for streaming music and video from one machine to another, how to give your home its own Twitter and e-mail accounts for sending automatic status reports, and the ability to remotely control the home lights or heating system. Also, Smart Home Automation with Linux describes how you can use speech synthesis and voice recognition systems as a means to converse with your household devices in new, futuristic, ways. Additionally, I’ll also show you how to implement computer-controlled alarm clocks that can speak your daily calendar, news reports, train delays, and local weather forecasts. You can then reuse this same weather data in conjunction with motion sensors to remind you to take an umbrella when you’re about to leave the house on days when the forecast calls for rain! I’ve written this book to document all the processes and lessons I’ve learned when creating my own smart and automated house, and now with the help of this book you can do the same.
