How to set up a smart home: The ultimate guide

A smart home is a house that uses technology to make life easier, safer, and more convenient. This technology is made up of devices and systems that can be controlled remotely, often through a smartphone, tablet, or voice commands, and each device is connected to the same network, so they communicate with each other and with you.

Some of the most popular smart home devices include things like smart lights, thermostats, security cameras, doorbells, and speakers. Some homes also have smart appliances, like refrigerators or washing machines, that can send you alerts or reminders.

Because all these devices are connected to the same network, you can set up routines with them working together, such as lights dimming at a certain time and the doors lock automatically at bedtime, or the heating turn off once the thermostat measures a specific temperature. This kind of setup helps save energy, improves security, and adds comfort to daily living.

Smart homes are becoming more popular because they help people manage their homes more efficiently while making daily tasks easier for everyone.

Here of just some of the reasons you should make your home smarter:

To set up your smart home, you’ll need to make sure you have all the basic equipment to get started. The main thing you’ll need an internet connection that’s fast enough to handle multiple smart devices at once. That’s because all your smart home devices need connect to the same internet connection, so if your WiFi is slow or weak, it may not be enough to keep your smart home running smoothly.

You’ll also need to make sure your WiFi router supports 2.4GHz frequency. Most smart home devices are designed to work on the 2.4GHz frequency band because 2.4GHz WiFi has a longer range and works better through walls, which is helpful for devices spread throughout your home.

Most routers, including Virgin Media Hubs, offer both 2.4GHz and 5GHz bands, so you can switch to the 2.4GHz band easily to set up your devices. If you’re a Virgin Media customer, read our full guide on 2.4Ghz vs 5Ghz to learn how to switch over to the frequency you need.

Once you’ve got your internet sorted, here's some of most popular the equipment many people have as part of their smart home setup:

• WiFi booster – to extend the WiFi signal

• Smart speaker or hub (like Amazon Echo or Google Nest) – optional, but helpful for voice control

• Smart lights – bulbs that you can turn on/off or dim with your phone or voice

• Smart thermostat – to control your heating and cooling

• Smart plugs – let you control regular appliances remotely

• Smart doorbell or camera – for added security and to see who’s at your door

• Smart lock – to lock or unlock your door without a key

Remember, you don’t need everything at once. It's best to start small, like with smart lights or a speaker, and slowly add more devices over time.

Setting up a smart home is simple if you take it step by step. You don’t need to do everything at once—you can start small and build your smart home over time.

Here’s our step by step guide to getting everything set up:

Step 1: Look at your WiFi Setup

The first thing you need to do before setting up your smart home is make sure you have a strong and reliable internet connection at home. Most smart devices connect to the internet, so your WiFi needs to reach all the rooms where you want to place smart devices and be fast enough to handle all of your different devices at once.

If you’ve got a large home and your WiFi is doesn’t reach certain rooms, you might need a Wi-Fi extender or a mesh Wi-Fi system to boost the signal so it can reach of all your devices. Make sure you set a strong password that you can remember too, as you'll need it when setting up your devices.

Step 2: Choose a Smart Assistant or Hub

A smart assistant lets you control your devices using your voice or one app. The most popular ones are:

• Amazon Alexa (works with Echo devices)

• Google Assistant (works with Google Nest)

• Apple HomeKit (uses Siri and the Home app on iPhones)

Pick one that works with your phone and the devices you plan to buy. A smart speaker or display (like an Echo Dot or Google Nest Hub) is a great way to talk to your devices. This assistant will become the “brain” of your smart home.

Step 3: Pick Your First Device

Now it’s time to pick your devices. It’s best to not set up everything at once, since you’ll need separate apps for each of your devices and it’s easy to get confused with all the different systems and setups. Insteand, start small so you can learn how it works. Good first choices include:

• Smart light bulbs – let you turn lights on/off or change brightness and color

• Smart plugs – control any device you plug in, like a fan or lamp

• Smart thermostat – helps control home temperature and save energy

• Smart speaker or display – helps with voice control and routines

We’d recommend choosing one or two devices that fit your needs and match your smart assistant. Make sure they say "Works with Alexa," "Works with Google," or "Works with Apple Home" on the box, and that’re compatible with the WiFi frequency you’re using.

Step 4: Download the Right App

Every smart device has an app that you need to install on your phone or tablet. This app will guide you through the setup process, but usually you’ll need to:

• Create an account (or sign in)

• Follow step-by-step instructions to connect the device to your WiFi

• Give your device a name (like “Living Room Lamp”)

Once you’re set up, the app lets you control your device, check settings, and sometimes see usage reports (like how much power you’ve saved).

Step 5: Connect to Your Smart Assistant

Now that your device is working, you can connect it to your smart assistant so you can control it with your voice. Open the assistant’s app (Alexa, Google Home, or Apple Home), and:

• Add or link the new device

• Follow prompts to give permission

• Group devices into rooms (like “Bedroom” or “Kitchen”) for easy control

Once it's set up, you can say things like: “Alexa, turn off the bedroom light” or “Hey Google, turn on the fan” to see if everything's working correctly.

Step 6: Add More Devices Slowly

As you get more comfortable, you can expand your smart home. Add new devices one at a time so setup stays simple. Some ideas for next steps:

• Smart locks – lock/unlock your doors from your phone

• Smart cameras or doorbells – see and talk to visitors

• Motion sensors – turn on lights when someone enters a room

• Smart appliances – like fridges, ovens, or vacuums you can control from your phone

Always check that any new device works with your smart assistant before you buy it. Over time, you’ll build a smart home that fits your life and makes daily tasks easier.

A good starting point for a small smart home is around 50 Mbps download speed. That’s enough for basic devices like smart lights, plugs, and thermostats to all work smoothly if there’s only a couple of you at home. But if you stream videos, play games online, or have many devices at home, you’ll want speeds of 100 Mbps or more to keep everything running smoothly.

Don’t forget, a strong WiFi signal throughout your home is just as important as speed. Even fast internet won’t help much if your devices can’t get a solid connection. If some rooms have weak WiFi, you might need to think about getting a WiFi booster or mesh Wifi system to fix that.
