Just like a smart person is considered to be more intelligent, when we call something smart it generally means that the object is more intelligent than previous versions.
However, it can be interpreted differently depending upon the object. For example, a ‘smart garden’ simply means an indoor garden that uses artificial lighting whereas a ‘smart motorway’ uses advanced traffic management systems. So, what exactly is the definition of a ‘smart home’?
A smart home is a home that is automated using devices and appliances that are connected to the internet. These devices, such as lights, thermostats, and plugs, can then be controlled remotely by the user or they can be automated to control themselves.
In the rest of this guide, I’ll explain what a smart home does, how they work, and how you can get started.
There are two main things that a smart home does:
At this point, you’re probably wondering why you’d want to control your devices remotely or for them to control themselves.
Well, here are some of the reasons why you’d want to do this:
So, what about the downsides of smart homes? Well, as with everything in life there are a few. Here’s a quick rundown:
If you’d like a more complete list, see my full article on the advantages and disadvantages of smart homes.
Smart homes work using a network of internet-connected devices that talk to each other in the cloud to get things done.
As these devices talk to each other, two basic things happen; a trigger and an action.
Most people will centre their smart home around one ecosystem such as Amazon Alexa, Google Home, Apple HomeKit, Samsung SmartThings, or Home Assistant.
By integrating all of your compatible devices into an ecosystem, you can manage them all in one place and create automations using triggers and actions as mentioned above. Below is a basic example of the process to turn on a smart lightbulb with a voice command:
Most popular ecosystems also intergrate smart assistants which can add voice control to your smart home.
Note: it is possible to use more than one ecosystem or none at all, but I’d recommend choosing one for beginners.
Whilst the terms smart home and home automation are often used interchangeably, there is a key difference between the two.
A smart home uses the internet to manage and control your devices whereas home automation tends to operate locally.
Home automation does not have as many advanced features as smart homes such as voice control, integrating your streaming services, and intelligent routines.
Popular home automation systems include Control4, Creston, and Insteon. This guide focuses on smart homes and not home automation.
How that you know what a smart home is and how they work, the next question is how to start one. Here are the basic steps you’ll need to follow to get started.
The first thing you should do is decide which ecosystem or platform you’d like to use. It’s best to do this right at the beginning to ensure all your devices are compatible, however, it’s not too difficult to change your mind as most devices will work with more than one platform.
The most popular ecosystem for starting out are:
Amazon’s Alexa has the broadest range of compatible devices out of all the smart home ecosystems. Alexa routines are the best for creating automations compared to the other two mentioned here as you can set a variety of different triggers.
Google Home is another popular pick that has a large selection of compatible devices. You can control them by speaking to Google Assistant which is the default assistant in android phones and Google’s smart speakers. It’s great for entertainment due to Chromecast technology and is best at understanding your commands thanks to Google’s natural language processing.
If your household is full of iPhone users, you’ll likely want to use Apple HomeKit. This ecosystem tends to have fewer compatible devices due to Apple’s standards, however, it is very easy to control from the Apple Home app or using Siri.
Once you have chosen your ecosystem, download the relevant app to your smartphone.
These aren’t the only options available, there’s also Samsung SmartThings, Home Assistant, and Hubitat.
The next step in starting a smart home is to get a smart speaker or smart display that will be used as a smart hub. These have built-in microphones for issuing voice commands to your connected devices.
The speaker or display you get will depend upon which smart home ecosystem you chose in the previous step;
There are various sizes of speakers and displays to suit your needs, all of them will work with your smart home but will have different audio and video quality. A smart display adds extra functionality but is not a requirement for starting your smart home.
Now you can begin building out your smart home. When you purchase a new device, ensure it is compatible with your chosen ecosystem. This will be clearly visible on the product listings page or the box in-store.
Some devices will use Wi-Fi whereas others will use Zigbee. There are pros and cons to both:
Zigbee: These devices require a hub to connect to the internet which adds cost. However, they are a mesh network which means your device only needs to be in range of one other similar zigbee device.
Wi-Fi: No hub is required for Wi-Fi devices as they connect straight to your router. However, the device will need to be in good range of the router to operate.
Both Zigbee and Wi-Fi devices can be used in the smart home, just ensure they are compatible with your ecosystem as mentioned earlier.
When you buy a smart device, you’ll first need to set it up using the manufacturer’s standard app. Only once you have followed the instructions to do this should you attempt to add it to your smart home ecosystem through the Alexa, Google Home, or Apple Home app.
Here are some of the best smart home devices to consider when getting started:
Smart Lighting - The simplest piece of smart home tech for beginners is a smart light. You have a few options, you can either opt for a smart lamp, a smart bulb that goes into an existing light, or a smart light switch that replaces your existing switches.
Smart Plugs - A smart plug can be used to turn any existing device into a smart one. You will be limited to basic on/off commands, but this can work well for fans, heaters, lamps, or other similar devices. You can also get smart power strips if you have multiple devices to connect.
Smart Locks - Smart locks allow you to lock and unlock your door without using a key. This can be via a keypad, smart tag, or your smartphone. It’s easy to monitor who arrives and leave s your home and you can issue virtual keys to neighbours or guests if they need them.
Video Doorbell - A video doorbell (also known as a smart doorbell) is a great way of adding extra security and convenience to your smart home. These allow you to answer your door from anywhere in the world and check in on your doorstep whenever you like.
Security Cameras - Wi-Fi security cameras allow you to monitor your home from your smartphone. You can receive alerts when motion is detected and quickly take a look. You can also link them with smart lights to act as a floodlight.
