Smart homes had their origins, as most innovations, in theory long before they become a reality. While science fiction writers, such as Ray Bradbury, depicted these homes throughout much of the 20th century, their genesis lies in the development of the systems that comprise them. The first 20 years of the 20th century saw the invention of the vacuum cleaner, dryer, washing machine, iron, and toaster. The first smart device was created approximately 45 years later. Known as the ECHO IV, it could turn home appliances on and off and control home temperatures; unfortunately, it did not sell well. Home automation technologies began to be built into luxury dwellings decades ago.
