I can think of at least three good reasons. The first is what you’re already guessed: plain old novelty. Being able to control everything from lamps to coffee makers and even curtains using a remote or a smartphone app just looks cool, and it gives you something to talk about whenever someone visits your house.
The second reason is convenience. As this website shows, companies like PD Building Automation can help homes and businesses find smart home solutions that make their daily lives easier. The more control of your house or business you have through your phone, the more you can get done without being home, getting up from your chair.
Finally, there are the financial incentives. Smart solutions are often more energy-efficient, and being able to control lamps, outlets, and appliances from a distance can also help you cut down on power waste. Investing in smart solutions can also boost the resale value of a home, making it an attractive prospect for homeowners.
