If you wish there was more time in the day, home automation can help. Once it’s set up, simple voice commands or mobile app finger taps keep the ball rolling.

Whether you're looking for your first smart device, expanding your collection, or making your devices cooperate, here are four steps for smart home beginners to leap into home automation. Before you know it, you’ll be living in a twenty-first-century smart home.

What is a smart home?

There’s no tried-and-true definition of a smart home. Generally, a smart home uses smart devices to automate and control household functions—often through mobile apps and voice commands. Smart homes have four benefits that save money and time: convenience, security, entertainment, and energy efficiency.

Getting started with home automation

1. Choose your first smart device

There are thousands of ways to automate your home—making it easy to go overboard on smart devices you don’t need. We suggest starting slowly with one or two smart devices before gradually adding more.

Top smart home device factors to consider

  • Cost: You can buy smart devices on almost any budget. Decide where your limits lie.
  • Setup: Stick to intuitive smart devices that match your skill level—some electrical devices (like smart thermostats and smart outlets) require more technical skills to set up than others.
  • Lifestyle: Everyone is different, so the smart gadget your neighbour swears by might not work for you. 
  • Research: Before buying, read customer opinions, buyer guides, and independent reviews. You don't need to do as much research as us (that's our job), but different perspectives always help.

Devices for starting a smart home

Below, we highlight some of our favourite products for smart home beginners that are easy to use, affordable, or too good to pass up.

We also include links to relevant comparisons of the best smart home products and possible combinations of devices to help you choose your next smart product.

A digital assistant or smart speaker is probably the best way to start automating your home. They work using voice commands, which are useful for setting timers, playing music and podcasts, and controlling other smart home products. The Amazon Echo Dot (5th Gen) is an affordable smart speaker that uses Amazon's Alexa smart home platform. And it supports hundreds of devices.

What to pair with your smart speaker

  • A smart light bulb to turn off at bedtime—no more leaving the warm covers to hit a light switch
  • A smart lock to check if the front door is secure
  • A smart thermostat to prepare your home office for work

Smart light bulbs are one of the cheapest and easiest ways to start automating your home. While we like multicolour light bulbs for their flexibility, we think the Philips Hue White A60 Smart Bulb is a good starting point (for around $30 each). It's easy to schedule and dim using a mobile app or your voice. It doesn't support multiple colours but is an affordable option from one of the best smart home brands.

What to pair with your smart light bulb

  • A garage door opener to activate your lights when you come home
  • A smart speaker to dim the lights before bedtime
  • A video doorbell to use the light bulb as a notification that a visitor's walking up the front steps

Smart plug

A smart thermostat boosts your home's comfort and energy efficiency. For example, it can shift your house’s temperatures higher or lower during periods of low activity (like when you're asleep or away). Our favourite smart thermostat is the Sensibo Air Smart Thermostat (about $160) because it learns your preferred temperature settings and works well with Apple HomeKit, Google Assistant, and Amazon Alexa.

Video doorbells are essentially security cameras for your porch. They allow you to see and speak with visitors at your door without opening it. One of our top doorbell camera picks is the Ring Video Doorbell, which is incredibly affordable and works using either a rechargeable battery or existing doorbell wiring.

What to pair with your video doorbell

  • A smart lock to let in friends and family
  • Smart lighting to improve safety and security

A smart lock can arm and disarm a security system, track when guests enter and exit, and eliminate the need to hide a spare key near your door. You can also remotely unlock it to free up a hand while carrying groceries. We like the Ultraloq U-Bolt Pro (about $250) for its versatile unlocking options.

What to pair with your smart lock

  • Garage door opener to alert smart lock to lock the front door when you leave
  • Smart lighting to activate when you're on vacation to make it look like someone's home

While a security camera's primary goal is to record events in and around your home, it can also act as a video intercom thanks to two-way audio. The Arlo Pro 5 is one of our favourite security cameras because it boasts excellent video quality and is compatible with tons of smart home devices.

What to pair with your security camera

  • Sensors to activate the camera automatically when a door or window opens
  • Smart speaker to play the sound of dogs barking when the camera detects motion
  • Smart light switch to activate the camera when you turn on exterior house lights at night

2. Choose your smart home platform

The biggest dilemma in the smart home is which platform to use. Using a single platform, your devices can talk to each other and you can control them in a central place.

This allows you to manage everything remotely through an app on your smartphone, or computer, or voice control using digital assistants like Alexa, Google Assistant, and Siri.

What is a smart hub?

A smart hub is traditionally a device that controls other devices through protocols like Z-Wave and Zigbee. Although this type of tangible hub still exists (Samsung SmartThings), it's becoming more common to see virtual hubs that link accounts of different Wi-Fi devices over the internet (Alexa, Google Assistant, and IFTTT).

While you want to maximise your devices' compatibility with each other, you won't find a single smart home system that works with everything. For now, your best bet is to use devices that work with multiple smart home platforms.

Do I need a hub for my smart home?

Not always. But hubs can be useful for managing a large number of devices—particularly ones that use Z-Wave and Zigbee. Hubs are also great for reducing the number of Wi-Fi devices on your home network if they're slowing down your internet connection.

3. Connect more devices

Once you sample what a smart home can offer, it's hard to resist adding more devices. As you do, consider these four categories to achieve balance: control, entertainment, security, and utilities. These categories can help turn your tech daydreams into a smart home that's helpful and uniquely yours.

Security and safetySecurity system, security camera, security sensor, smart lock, video doorbell, smoke and CO detector, siren
Utilities and energySmart thermostat, smart lighting, smart plug, smart sprinkler, water leak detector, sensor

4. Create routines and automations

A smart home's ultimate goal is devices working together to streamline your day. There are two ways to make your devices work for you: routines and automations.


Routines group device functions together under a single command—some companies call them scenes or shortcuts. This allows you to change multiple settings at once to skip the burdensome and slow process of using manual controls one by one on a smartphone app or smart speaker.

Scenes and routines are useful in two ways:

  • To control multiple settings on a single device. For example, adjust a smart bulb to the right brightness and colour to set the mood as you curl up with a good book.
  • To control multiple settings across a group of devices. A good example would be playing music from your smart speaker, increasing the brightness of lights, and turning down the thermostat for an exercise session.

While the process for creating routines, scenes, and shortcuts varies slightly from app to app, the steps are often universally easy:

  1. Find out where the app allows you to create routines.
  2. Select the device(s) you want to control.
  3. Adjust the device settings to your liking.
  4. Give the routine a simple or memorable name—especially helpful if you plan to activate it using a smart speaker.
  5. Try out your new routine to see if it's working correctly.


Automations use a cause/effect structure that allows devices to react automatically to changing conditions in your home. While they have a longer setup process and require more critical thinking than routines, they're the pinnacle of smart home convenience.

Setting up automation consists of two parts: choosing what activates the system and specifying how the system reacts. Here are some common triggers and actions you can mix and match in most smart home systems:

If this happens
Then do this
ScheduleControl a device
Voice or app commandActivate a routine
Device or system status changesChange system mode
Your location changes (geofencing)Send a notification or message
  • Setting a schedule allows you to control when devices turn on/off during the day. It's handy for predictable events like waking up and going to bed.
  • Voice and app commands are the most common ways to activate routines. They're helpful for manually starting devices on demand, like when you want more light in the kitchen.
  • Status changes allow the system to react to different stimuli. These are especially great for security since they can tell a sensor to send a notification or sound an alarm when there's activity.
  • Geofencing allows the system to change settings based on your location. This is useful for preparing an empty house for your arrival after work or locking up when you go to the store.
Light Bulb
Automatic night light

One of my favourite automations is a night light that uses a colour smart bulb and a motion sensor. I created a routine where the motion sensor turns the light on at a dim orange setting to avoid blinding me when I walk down the stairs. This triggers a second routine: the light turns off when there's no motion for two minutes. Both routines start working when I tell my Google Home assistant that it's bedtime and turns off automatically at sunrise.


Homes vary in size and layout, so it's difficult to put an exact cost on a DIY home automation system. Depending on the devices you choose, expect to spend $500–$2,000 on smart home equipment.

The interconnected nature of smart home technology means there's always a chance that someone can hack into your equipment. You can minimise threats by sticking with trusted manufacturers, using strong passwords, and setting up two-factor authentication if available.
