We are living in a world that is constantly becoming smarter and smarter everyday. New smart devices are being worked on everyday, with many already available on the market. We are going to take a look at some of the already existing smart devices.
Smart Voice Assistant
Having a smart voice assistant can be very handy, especially when combined with other different smart devices. It allows you to to control other smart devices just by asking it to. For example, when I get home at the end of the day I can simply take all my shoes, walk over to sit on my couch and ask my Google Home to start casting whatever I want to watch from Netflix, and it will cast it to my Chromecast for me. There are other voice assistants such as Amazon Alexa.

Smart Plug
A smart plug is an adapter that you can plug into a normal outlet, and then plug another device into. You can then use your phone or a voice assistant to turn the outlet off and on. This past holiday season I was struggling with what to get my father, until I found a reasonable deal on a Google Home and a smart plug in, so I decided on that, hoping he would like it. By Boxing day he had already had both of them set on, and was able to turn their lamp off and on either by simply asking his Google home! Currently I do not own one of these, but I plan on getting one before next Christmas so that I can turn my tree lights off and on without having to crawl under the tree.
Smart Lights

Smart lights allow you to easily control the lights in your house through an app on your phone, or even through a virtual assistant like Google Home or Alexa. That means when you are laying in bed ready for bed but forgot to turn the light off, rather getting out of the warm bed you can simply turn it off from your phone. This also ensures you never have to worry while away that you left the light on, since you can just pull up the app and turn it off. Many smart lights also offer great features like the ability to dim the lights from your phone, change the color of the lights, and a few more advanced ones can even play music!
Smart Thermostat
A smart thermostat is a thermostat that offers the ability to program temperature settings based around the weather, your daily schedule, and your sleep schedule. This can be very convenient for making sure the temperature is nice and warm when you are just waking up, or when you will be arriving home from work, and ensuring the temperature is cooler when you are sleeping or at work. This can ensure as little energy/money as possible is wasted. You can also control the temperature from your smartphone if any changes in your schedule come up. Before purchasing a smart thermostat it is always a good idea to check to ensure your houses heating unit is compatible with the one you are going to get.
