In a smart home, you can set your devices and home appliances to work automatically or to respond to your behaviour. You can also control them remotely and use them to monitor your home when you’re away. Creating a smart home can make your home a more comfortable and easy place to live. As well as this, smart home appliances and devices have other benefits. Smart homes are also more energy efficient, they’re safer and more secure, and you can add things like entertainment or accessibility assistance.

Knowing where to start with a smart home isn’t always clear. If you don’t know how smart homes work, you won’t know what smart home technology to choose, how to create a control system and how to install everything in your home.

In this guide, we’ll explain what a smart home is and how they work. We’ll tell you how different smart home appliances and devices work so you can choose the right ones. Plus, we’ll tell you everything you need to know to set up a smart system in your home.

In brief: A smart home is a house equipped with internet-connected devices that can be controlled remotely or automated to perform tasks.

Saving money: Smart devices and appliances can help optimize energy usage as they can be set up to turn devices off when they're not needed and adapt to your habits, which can save you money on your energy bills.

Advantage: Smart home products can improve productivity by automating everyday tasks and helping users stay organised.

Caution: Not all smart devices work seamlessly together, and connected devices can collect data. It's important to choose compatible products, keep software updated, use strong passwords, and understand each device's privacy settings.

A smart home is a home fitted with smart devices and appliances that you control over the internet. In a smart home, you can set your devices and appliances to work automatically or responsively. As well as this, you can remotely control and monitor them over the internet. You can control your smart home through a central control device in your house or through an app on your phone or tablet.

Some common pieces of smart technology for homes are smart speakers, thermostats, door locks, cameras, doorbells and light bulbs. Smart devices can do simple tasks like automatically turning on at a set time. Otherwise, they can use advanced technology, such as location services.

Smart home devices and appliances operate to automate tasks at home and to allow us to remotely monitor our homes or perform tasks while we’re away.

At the centre of every smart home is a control ecosystem and a control hub. The control ecosystem is a management system that connects to all your smart devices, enabling you to control how they function and how your entire smart home system works. Control ecosystems normally work with a digital assistant like Google Assistant, Amazon Alexa or Apple’s Siri.

Your control hub is the point at which you interact with your digital assistant to control your smart home. Normally, this is a dedicated smart home hub, a smart display or a smart speaker. As well as using a control hub, you can also access and control smart home appliances and devices directly or through other applications.

The costs to set up a smart home can vary significantly depending on which smart home devices are purchased, how many there are, and how they are connected.

If you want to know how to set up a smart home on a budget, you can start with something as simple as a smart light bulb or smart speaker which can be a good low cost starting point. The system can then be built upon, with new smart home kits being added over time.

Smart home devices are more affordable when bought individually, and the costs can quickly stack up. But, setting up a smart home should be seen as an investment because there are many benefits which we’ll run through later in this guide.

Firstly start by identifying your goals. Common ones include improving security, reducing energy bills, increasing convenience, or automating daily routines. This will help you choose the right devices instead of buying randomly.

Step 1. Choose a smart home ecosystem
Pick a platform that will connect your devices together, such as Amazon Alexa, Google Home, or Apple HomeKit. Sticking to one ecosystem makes setup and control much simpler.
 

Step 2. Set up routines, schedules and general settings
You can set up devices to operate according to routines and schedules. This will create a basic home operation system that fits in with your normal life pattern. For example, you might set your kitchen coffee machine and the lights in your kitchen to come on automatically every weekday morning at a certain time. Routines and schedules can always be overridden by command or by automatic and intelligent settings later on if needs be. With automatic and intelligent settings, you can create a more advanced system that responds to your behaviour. This will make your home more comfortable, and it could save you money on your energy bills.

You could use geotargeting, to turn your heating on whenever you are 15-30 minutes away from your home, or set thermostats to learn your schedule and adapt to your routines. Alternatively, appliances might be set to run in tandem with solar panels to save energy.
 

Step 3. Set up IFTTT (If this, then that)
IFTTT is an app that you can use to connect and integrate different home smart devices together. It’s best if you can simply choose compatible devices that don’t need additional management applications, however, many people find IFTTT useful. You can use it to integrate devices that aren’t normally compatible, and it’s also useful for creating advanced automatic operations with compatible devices. You can use IFTTT to set up triggers that lead to action. For example, when someone unlocks the front door with a smart lock (the trigger), the system might turn the lights on in the hallway (the action).
 

Step 4. Check security
After you’ve set up your smart home, it’s a good idea to check if it's secure.
Here are some steps you can take to protect your security and privacy:

• Secure your Wi-Fi.
• Make sure you’re using strong passwords.
• Set up two-factor authentication.
• Disable unnecessary device features.
• Use a firewall.
• Use a VPN when you’re accessing your system from outside your home.

​​​​​​​It’s also a good idea to stick to established brands and remember to keep device software up to date.

Benefits:

• More comfortable and convenient living - There are a huge range of smart devices for homes with a number of different functions. You can also program them to work automatically, and you can control them from anywhere in the world.

• Increased productivity - Home smart devices can boost personal productivity by automatically handling routine tasks and creating a more organised way of life. You can program devices to make your morning coffee, turn on the lights when you wake up or set reminders throughout the day.

• Saving money on energy bills - A smart home can help you reduce unnecessary energy use by only operating when needed. For example, you can adjust temperatures automatically, turn lights off when rooms are unoccupied and set watering schedules based on weather conditions.

• Increase your home security - Security cameras allow you to monitor activity in your home from anywhere in the world, and notifies you immediately if there’s suspicious activity. Also, smart lighting can be programmed to make your home look occupied when you’re away. 

• Increase accessibility - Smart home technology is also great for people with disabilities and accessibility needs. Being able to control home devices and appliances through voice commands or from a screen is a great boost for people who normally struggle with tasks. Tasks that might require help or take people longer than others can often be done with little or no direct involvement.

Drawbacks:

• Installation - Fitting an entire smart home system from scratch can be complicated. You need to plan carefully, and it might be that you run into problems and challenges when you’re trying to organise everything. Some smart devices will need to be wired in by professionals too.

• Initial cost - Turning your home into a smart home usually means investing money at the outset. If you want to set up a large smart home system all at once, the cost might be quite high. Even simpler systems come at a cost. Some particular home smart devices and appliances can also be expensive by themselves. If cost is an issue, one good approach is to build the system up over time to spread out the cost.

• Potential security problems - Although smart homes are generally secure, they could be targeted by hackers. Cybercriminals may attempt to gain access to devices such as smart locks, security cameras or alarm systems, to monitor activity or gain entry to a property. To reduce these risks, you should use strong passwords, enable security features and keep up to date with the latest software.

• Dependence on the internet - some smart home products rely on an internet connection. If the internet goes down, some devices may lose functionality or become difficult to control remotely.

Smart device compatibility: Smart home devices work best when they are compatible with a single ecosystem such as Google Assistant, Amazon Alexa, Apple HomeKit or Samsung SmartThings, allowing easier control from one central app. While separate systems can be linked using hubs like Home Assistant, Hubitat or IFTTT, this adds complexity and may limit some features. Choosing one ecosystem first and buying compatible devices is usually the simplest approach.

 

Connectivity mode – Internet vs Bluetooth: Smart home devices typically connect via Wi-Fi or Ethernet, allowing remote control from anywhere and easier integration with other systems due to higher data capacity. In contrast, Bluetooth devices only work within a limited range and cannot be controlled remotely unless a separate gateway is used, making them less flexible for full smart home setups.

 

Household Wi-Fi strength: Wi-Fi smart devices depend on a strong and reliable internet connection, but some areas of the home - especially outdoors - may have weak signal coverage. To improve performance, it’s important to place the router in a central location and use Wi-Fi extenders if needed. Upgrading to a smart router can also offer extra features, although it is not essential for running a smart home.

 

Security and privacy: Smart devices for homes are vulnerable to hacking. Hackers might try to gain access to smart devices like door locks, cameras or alarms to monitor people’s activity, gain entry to their homes or for other reasons.

Smart home devices can be made safer by taking precautions. Some good things to do are to stick with established brands when you’re buying devices, use strong passwords, set up two-factor authentication and keep your software up to date. You can also disable unnecessary features, use a firewall and use a VPN when you’re accessing your system from outside your home. It’s also a good idea to check the manufacturer’s privacy policies and choose what data you let them collect and share.
