Smart Home: A Comprehensive Guide

Smart Home: A Comprehensive Guide

With the technology progressing on a rapid-fire, not only are our gadgets getting smarter but our houses too. That being said, it allows you to automate your house core activities.
For instance, a Wi-Fi doorbell helps you monitor your door when you are out on holiday. Similarly, if you forgot to turn off lights or heat while going to the office, you can do all that while sitting at your office chair by using a smart home technology system. That's cool, isn’t it?
We are a team of smart home geeks working in this industry for over a decade. Every now and then, we come across many questions our customers ask, like what is a smart home? How does a smart home work? And how can I build my smart home?
At iSmartHomeSecurity, we are always open to answering your queries related to a smart home. So let's answer your questions first!

1. What is a Smart Home?

Home automation means automating your household activities. By doing so, we use smart technologies that make our homes smart.

You have to connect Smart Home devices in the house that enable you to control certain activities remotely. The best thing about a smart house is that everything is under control at your fingertips.

Smart home devices work on these principles:

  1. Smart home technology is about connecting smart home appliances and devices to the Internet. You can remote control or monitor the home system via your smartphone, computer or tablet.
  2. Since all devices are interconnected through the Internet, you can manage them using one device to trigger another for specific tasks. Such as, you can set up a Wi-Fi light to turn on using a Smart Home assistant.
  3. If connected with the IFTTT, then they communicate seamlessly with each other. It helps in having a better user experience as one device will tell others what you need.
  4. Other smart home technologies are becoming more and more popular due to artificial intelligence (AI). It allows devices to adapt to human preferences and the environment. For example, Amazon Echo, a voice assistant, makes your life simple with just voice commands. With it, you can call anyone in the home while not leaving your space.

1.1 Smart Home examples

  • According to situations, from a single touch, you can adjust specific lights for a friendly get-together, a romantic dinner, or a family movie night.
  • Smart TVs connect to the Internet to access content through applications, such as on-demand video and music. Some smart TVs also include voice or gesture recognition.
  • A thermostat allows you to control air temperature with voice commands.
  • Smart Grill alerts you on your smart device: when your grill is preheated, the internal meat temperature, and when your meat or fish is fully cooked.

2. Where Does Smart Home Benefit Us?

 Remote Monitoring

You can manage, control and operate your smart house devices anywhere, anytime. You can also have a real-time check-on on multiple elements at your house.

 Save Cost

You can save costs by remotely controlling smart home devices via apps on your smartphone and even monitoring usage to control consumption.

 Energy Management

Managing utilities such as heating, cooling, and lighting can save on energy costs.

 Video Analytics

One of the most significant features of the smart home is video analytics.

 Appliance Safety

Smart stoves and grilles turn off appliances automatically. This provides real-time monitoring of hazards, such as being left on a hot stove, grill, or oven.

 Increase Home Safety

Smart home devices come with a built-in alarm system, especially door locks and smart cameras, double the home security. You can check in your house from anywhere in the world and lock it from there.

3. How Does Smart Home Work?

Smart home works in 3 main steps.

  • Devices: The first step is to connect smart devices to the Internet.
  • Transmit: Wi-Fi, ZigBee, and Z-Wave are some of the most common smart home communication protocols in use today.
  • Cloud: Finally, seamless communication between smart devices is made possible through Cloud. Cloud processes the vast amount of data that these devices generate. It acts as a bridge in the form of a mediator or communication facilitator.

One of the most powerful ways to make smart home devices work together is by connecting them with your IFTTT account.


3.1 What Is IFTTT?

It is derived from a programming statement that stands for "If This, Then That."

IFTTT is an automation tool that links different devices together.

Why do you need to look at IFTTT when you buy a smart home product? Because smart homes are really a big catalogue (all of home use). Only devices that work with IFTTT can know each other.

3.2 How Does IFTTT Work?

Normally manufacturer or brand companies will integrate the IFTTT function into their product before going to market. In most cases, as a user, we just need to find the product with IFTTT marked.

For some DIY person, if you really want to build IFTTT by yourself, IFTTT works in 4 simple steps:

  1. Create a free account.
  2. Browse the IFTTT website or app to find what interests you.
  3. Connect the services that are involved in the Applet or connection.
  4. Find more Applets and connections, and repeat! 

IFTTT also has videos on how to build and connect an applet. Do check them! Moreover, check IFTTT plans here.

7. What is Home Security?  


Some people are usually confused between a smart home and home security. Home Security is a subset of Smart Home. 

It is a method to secure your house through a system of interconnected and networking security devices.

The home security system is a network of integrated electronic devices working together. They have a central control panel to manage and operate every device with just one button. It protects against burglars and other potential home intruders.


8.1 How Does Home Security Work?

When there is an emergency in your house, the alarm system triggers and sends an emergency message to the central station of your service provider. It acts as a bridge.

When the central station receives the message, they respond immediately. They contact the authorities and inform you about the emergency.


8.2 What You Should Know Before Buying A Home Security System

If you decided to buy a home security system for your house but lost where to start, here are a couple of tips. They will help you to understand the process much better.

You can buy a DIY alarm system or a professional alarm system. Both have their own advantages and disadvantages.Let’s check them.


DIY Alarm System

A DIY alarm system is suitable for those who don’t have a multi-story building. They are also suitable for those with fewer residents in the house. But as the name suggests, you have to do the installation and maintenance all by yourself.

In a DIY alarm system, you are not confined to buying all equipment at once. You can buy the most needed first and other parts later. This also helps to manage the cost and expense.

Typically, this type of system costs you less as you are only paying for the device. And all the installation work is done yourself. The price starts from $100 and goes up depending on the device and its type. Spend once, and then just do the maintenance.


  • It costs less
  • Flexibility to buy devices depending on your budget
  • Select the device on your own
  • Control your appliances from anywhere


  • Installation is sometimes a hectic and time consuming task
  • Sometimes maintenance also becomes difficult

Professional Alarm System


A professional alarm system is suitable for multi-story buildings and with more residents. A company’s skilled team workers install the whole system in your house, don’t expect any mistakes or issues in installation.

In this type, you have to buy the whole set of appliances at once. In this way, it becomes quite expensive, isn’t it? Besides that, you’ve to pay extra monthly charges to a company for maintenance and security.

If you can afford, it’s the best option you can go for, because you don’t have to worry about anything. Now, it’s all on them; you just relax.

However, the cost may vary from company to company, and of course, the state too. But they usually start from more than a couple of hundred dollars along with monthly fees of around $25.


  • Handled and installed by professionals

  7. Install high-resolution cameras so you can zoom in on the intruder’s face




9. What Are Compatible Devices for Smart Home?

Smart home devices must be able to exchange information on multiple devices. To do so, they need to speak the same language and communication protocol.

Common Communication Protocols: 

  1. Infrared light
  2. Ethernet
  3. Wi-Fi
  4. Bluetooth
  5. Zigbee
  6. Z-Wave
