IoT — Home Automation

It was a dream that the home was automated. Everything could happen automatically, from switching the lights, opening, and closing of the door to the automatic surveillance systems. This dream of Smart Home or Home Automation is slowly becoming true. A smart home can be referred to as a home setup where appliances and devices can be controlled remotely from anywhere with an internet connection.

The global market share for smart home automation has reached more than $75 billion in 2020. It is estimated that this rise to $150 by 2025, at a CAGR of 11.6%. This growth is driven by various factors such as the increasing number of smartphones, less internet cost, growing the importance of monitoring homes, and the most important saving energy.

Since the number of IoT devices has been increasing exponentially, it is becoming easy to offer some great smart homes. IoT systems depend on the collection of data. The information is then used to monitor, control, and transfer data to other devices over the internet. This enables specific actions to be launched automatically whenever certain circumstances arise. Consider the smart kettle as an example. When the kettle reaches a certain temperature, it can be configured to turn off automatically.

Here are some scenarios of Smart Home

Smart Lighting

Smart lighting is all the rage these days. They can be programmed to turn on and off, as well as to adjust their strength. It is likely, however, that this might be taken a step further in the future. The lights will respond to other actions you take if you have IoT activated in your home.

The lights, for example, will react to your home theatre. When you start watching a movie, they can turn off or dim. Further, they may respond to the type of film being shown. They will, for example, switch off completely if the lights detect that you are watching a horror film, providing the necessary atmosphere.

Smart Door

Smart locks make getting into and out of your building, apartment, or dorm a breeze. Use your mobile to open your door remotely or ask a voice assistant to do it for you. This could be achieved with the aid of a mobile device or facial recognition. This can be taken a step further by having the rest of the house participate in your entry.

The lights, for example, can turn on as soon as you step through the door. They can even be switched off if you are going.


Windows can get wise as well. Imagine them opening and shutting the skylights automatically as the sun rises and falls. You would also be able to schedule them to automatically close when it rains. For example, when you’re watching a movie, you should lower the curtains.


You can also use software to monitor your home thermostat from afar. You do not even need to do that in the future. When you get close to your door, the thermostat can detect it. It will then check the temperature in the room as well as the outside temperature and set the appropriate temperature for you. It might also be able to sense whether you are showering or exercising and change accordingly.

Home routines

This is my personal favorite. A significant part of the house can now be connected to smart devices. There are smart sockets that switch machines on and off automatically. Smart alarm clocks will play music or even send you the news when you wake up. Voice assistants will also monitor lighting, appliances, thermostats, alarms, and other gadgets as part of a routine. On a single command like “Hey Google, Good Morning”, a set of commands are executed. To help you get out of the grogginess, the shutters will open just before you wake up. The coffee maker will begin brewing your morning cup even before you awake. The water for your shower will be hot in the bathroom. As you drink your morning coffee, your stereo will begin to play some morning music. Your television will also turn on and view your choice news channel. And of course, the thermostat will adjust to a comfortable temperature.


Much of this, of course, will not happen immediately. The most important impediment to widespread acceptance of IoT-enabled smart homes is cost. Another big issue is privacy. Then there are the existing technical shortcomings that make it difficult to attach multiple IoT devices seamlessly.
