Using IoT for Home Automation


Have you ever wondered if you turned off the lights, the gas stove or locked the door? Wouldn’t it be great if you could check your home from a great distance and turn anything on or off? IoT (Internet of Things) is for you as it makes your home a smart home.

Even though we still don’t have flying cars, some of people’s fantasies about life in the 21st century have already become reality. One example of this is smart homes using IoT, which are full of devices that automate our everyday routines. It is estimated that most homes around the world will start using IoT in the coming years.

This is one of the most widely used applications of IoT, the smart home or home automation concept that is knocking at our door. Devices started working together to make our homes more comfortable and easier to navigate. But what exactly is the role of IoT in the operation of smart homes?

Let us discuss the role of IoT in smart homes, its benefits, how IoT works in home automation, etc.

What is IoT Home Automation? 

Smart home gadgets such as thermostats, lighting, appliances and smart TVs are transforming homes as they become integrated systems. They help us make more informed and effective energy consumption, safety and comfort choices.

A smart home system can make our lives easier. Starting with energy management, the power control system in our AC devices manages to reduce power consumption. A door management system, security management system, security management system and water management system are part of it.

The limitations of IoT in smart home applications stop where our imagination stops. Anything we want to automate or make our lives more accessible can be part of a smart home or smartphone system.

The role of IoT for smart homes

A home can be called smart when it has multiple smart devices that you can control remotely and combine into one network. This uses smart devices connected to a single network via hardwired or wireless systems such as Zigbee, Wi-Fi, Bluetooth and NFC.

Using Internet of Things technology, your smart appliances can perform real-time data communication and sharing. This allows devices to perform scheduled and automated tasks.

IoT home gadgets bounce data back and forth using sensors, learning your patterns and processing them to automatically adjust to your convenience. Some smart home Internet of Things applications are automatic light switches, burglar alarms, and voice-activated sound systems.

Role of IoT for Smart Homes

But the magic begins when IoT joins this team. It provides Internet access to all devices, thereby widening the possibilities of such a home network. For example, you can now see what is happening in your home by looking at security cameras through your smartphone or computer.

IoT applications allow you to connect devices and make them communicate without your involvement. Imagine, when your car leaves the parking lot near the office, the conditioner starts cooling your house so that you can enter a pleasantly cool house after a hot day.

Smart Home Devices

Smart home devices are Internet of Things (IoT) devices designed to automate and enhance various aspects of a home. These devices are connected to the Internet and can be controlled remotely via mobile apps or voice commands. They provide convenience, energy, and improved home security.

Here are some of the commonly used IoT smart home devices:-

How does IoT make a home smart?

  • Basic Setup

With a complex architecture, an IoT home automation system consists of remote servers along with sensors, where servers on the cloud manage multiple sensors simultaneously. IoT sensors communicate via Bluetooth, ZigBee, Wi-Fi, and Z-Wave. 

The main device of the system is a controller, often called a gateway or hub, which is connected to the home router via Ethernet. Sensors send and receive commands through this centralized gateway. All devices are interconnected and can establish a sequence of actions, making it possible to monitor IoT gadgets remotely through an application.

  • Cloud Connection

Data stored and maintained in the cloud over the Internet allows you to access IoT devices regardless of your physical location.

You can send commands to the hub no matter how far away you are from home. After receiving the command, the hub sends a signal to the sensor, triggering the requested action, then the hub updates the device’s status to provide the appropriate information.

These are typically enabled using systems such as SaaS IoT platforms.

  • Real-time monitoring and notifications

The hub is connected to the cloud network using the internet. You can plan the trigger action and monitor the updates on a regular schedule. The cloud network receives the input and sends it to the hub, which triggers the action. Later, you will be notified about the changed state. All the changes will be noticed in your smart device. Here, the use of open source IoT platform is key.

  • IFTTT (If This Then That) integration

You can set up continuous actions with the help of IFTTT integration. The action will be performed only when the criteria is met. For example, if the sensors detect rain or snow, the windows will automatically close to protect your home.

Benefits of IoT in smart homes

A cool home on a hot day – that is not the only advantage you get. Let us now look at the most important advantages of IoT smart home applications –

A cool home on a hot day – that’s not the only advantage you benefit from. Let’s now look at the most important benefits of IoT smart home applications.

1. Control and monitoring

IoT significantly improves how you can control and monitor all the processes at your home. The refrigerator can notify you if your yogurt will spoil in two days or add milk to the shopping list. Every day IoT applications collect data about how your home works, process it and show you the most important insights.

2. Cost and Energy Savings

With detailed statistics about the function and energy consumption of each smart device, you can easily optimize their use and adjust your smart home settings cost-effectively. You can also allow your smart home system to do everything independently. The system will turn off devices that are not in use and reduce energy consumption.

3. Environmental Impact

Apart from reducing your bills, energy savings help reduce the negative environmental impact.

4. Better Security

A smart home security system is an excellent tool for protecting your property because it controls everything inside and outside your home. Security cameras, smart locks, motion, smoke, and other sensors – all these gadgets work together and notify you when something is wrong. You can check what is happening in and around your home while sitting in the office or lying on a beach across the world.

5. Comfort

People always want everything to be more comfortable and convenient, and IoT in smart homes is perhaps the greatest achievement in this direction. It is fully capable of simplifying and improving your life: many processes in your home run autonomously, yet the overall control remains in your hands. Isn’t this the future our ancestors dreamed of?
