When we live in homes, we try to make our homes cozy and comfortable for ourselves. These days, smart home technology makes the home cozy and sets it to live more comfortably. This is all possible thanks to the development of networks, IoT devices and all kinds of technologies. Let’s learn about these smart homes and why we might want to try to make our homes smart!

● Smart Home’s Birth and Growth
The definition of a smart home is a ‘linked’ home or a home connected to a network. In a smart home, almost every home appliance is linked into a network and platform software. In the early stages of the smart home, we could use our smartphones to control things in the house like the lights, gas valves, and air conditioning. Now, controlling the home has become more convenient with AI applications such as AI speakers and AI software. The software collects information about the owner’s lifestyle and sets the house according to the owner’s preferences.

● Is a Smart Home Perfect?
Just as everything has its own bright and dark sides, so too does a smart home. There are a few advantages of a smart home to consider. First, we can save energy and make up for our simple mistakes. For example, if you left your air conditioner on when you left the house and you realized it later, what could you do? If your home is connected, you can just turn it off with phones which save time and money. Also, smart home technology helps us think less about the home by setting itself to our needs automatically. If you live alone, there is no one to turn on the lights and warm up your cold home for you before you get back. However, with AI technology and smart homes, the home welcomes you with an adequate, comfortable temperature and lighting when you arrive.
On the other hand, it has three disadvantages as well. In construction, if we want to have a stable building, we need to build a strong base. Similarly, in smart homes, the platform software is the basis of all the IoT devices. However, there are many IoT device manufacturers but no clear common platform yet, like Android or IOS. For this reason, it is hard to optimize the software for all these devices. Another consideration would be security problems that also might appear. A home is a place where many private activities occur. Therefore we need to be especially careful about our privacy and security. Lastly, while smart home appliances have a long lifespan, technology varies and advances quickly. Usually, most families use their appliances for up to 10 years before they break or become obsolete. This means that the hardware will be the same for a long time even though there may be software updates.

● Smart Home’s It-Item
There are some necessities for smart home technology. Let’s look at what some of them are and their roles in a smart home.
1. Network
Smart homes are efficient because they can be controlled without the owner actually being inside the home. So the network is a must and basic need for the smart home. The most commonly used network is Wi-fi but LTE or Bluetooth can also be used for connectivity.
2. Sensors and IoT devices
If there is only a network, it is like a country without people. The sensors and devices are the people in this case. The sensors sense the presence of the owners and try to also sense the owner’s needs by predicting the owner’s activities, based on regular habits. The devices are also necessary because most of our conventional appliances are not ‘smart’ nor have the hardware needed for connectivity.
3. Programming
A Smart home’s best advantage would be that people can control the smart devices and appliances in the house from outside. Most of these programs controls? are in the form of applications in the smartphone.

● Reform Your Home to Be Smarter!
Are you tired of always forgetting to turn off the lights or gas? Do you want your home to be warm before you arrive? If you want, you can do! Make your home a smart home! It would be doubt to someone that even there is nothing to be smart home in your home. There are some solutions that you can find to change your home into a smart home.
At first, you can change your bulbs into smart bulbs. These days, there are some smart bulbs that you can control from outside. Or if it were too bright or dim, you could adjust the lighting. This smart bulb was produced by Philips, a well-known electronic appliance company. Second, say ‘Hi!’ to your speaker, AI speaker that is. The AI speaker might be an enormous invention nowadays because many people can ask it how the weather outside is, to turn songs on for their particular mood, and inform us when the bus will arrive. Knowingly or not, an AI speaker is a good assistant in our life. Just like this AI speaker, in your phone, if you called “Hi, Bixby, Siri” or other name that they have, they would help you instantly. Third, if you want to make adjustments to your home to make it smarter, but you haven’t planned to change your home appliances yet, then an AI sensor will help make your home smarter. LG Electronics released an AI sensor called a ThinQ sensor. ThinQ sensor can make your appliances smarter than before. For example, this sensor can alarm you when your laundry is about to finish. Or it can sense your home’s humidity and temperature. You can know your home in a more detailed way. Of course, if you want to make a perfect and up to date smart home, it would be better to move to a home already containing the infrastructure for a smart home.

Having a smart home is good and cozy. However, we should always be careful about convenience. Too much convenience might bring major problems like security breaches and too much energy usage. We should be wise about how we use our smart home. Technology develops quickly, and now, it is time to think about how to use it properly.
