Most of us spend all day at school or work. After a long and busy day, all we want to do is to return to a comfortable home. Smart technology can turn any home into a nicer place to live in.

Smart homes have been around for some time. Scottish company Pico Electronics invented a type of technology called X10 in 1975. It allows household devices(设备), such as lights and alarms, to communicate with each other by using radio waves, according to AVSytemsMag, a specialized magazine in the audiovisual and automation(视听及自动化)industry.

Of course, 5G network connectivity has made smart homes more convenient. Perhaps the most widespread smart home technology is the voice-activated assistant(语音激活助手)Google Home and Amazon's Alexa allow users to control nearly any device in their home simply by speaking a few words. This is especially convenient for people with physical disabilities, as they can finish tasks that would normally be too difficult, according to How-To Geek.

Common household appliances(家用电器)can become "smart" as well. For example, a smart trash bin can memorize all the things you've thrown away and offer you a shopping list online, while a smart fridge can create dinner recipes(菜谱)based on the vegetables that are being kept inside, according to HowStuffWorks.

But it's not just about convenience. Smart homes are also good for the environment. By regularly checking your energy use and automatically turning off lights and other devices that you're not using, smart homes can lower how much electricity you use overall. Using less energy means that we make less pollution, which is good for the environment.

Not everyone is excited about smart home. In fact,
