Smart homes allow homeowners to control and monitor functions like lighting, temperature, and appliances remotely using a smartphone or computer. The idea originated in a 1989 science fiction story, but the first smart devices did not appear until 1997. Advantages of smart homes include energy efficiency, convenience, safety features, and customization, but disadvantages include potential privacy and security issues. A survey found that while many respondents were unfamiliar with or unable to afford smart homes, nearly half would consider using them due to perceived benefits. Overall, smart homes are expected to become more popular as supporting technologies continue to develop and prices decline.
