This guide will cover the gear that’s currently available, how you can get your smart devices to talk to each other, and some of the problems you might have to solve to make your home the most well-connected building on the block.

Smart home devices

Over the last few years, smart homes have seemed to teeter on the verge of reality—a futuristic idea that’s close but not quite here yet. In fact, smart-home products already fill the shelves of online and physical stores. Welcome to the future. Devices that you can pick up include smart lights, smart door locks, smart thermostats, smart security cameras, smart plug sockets, smart speakers, and more besides. What makes something “smart”? We’re typically talking about a product with an internet connection that you can control with your phone or via a central hub. Also, smart devices often “learn” more about its users’ habits as they go. Take the well-known example of the Nest thermostat, which actually launched way back in 2011. You can control it over the web and from your phone, and it gradually picks up on your heating schedule and becomes clever enough to make adjustments automatically. Meanwhile, some manufacturers produce entire ranges of smart home equipment, like the SmartThings line owned by Samsung. The kit covers motion sensors, lights, smart plugs, door locks and more. Buying smart devices from the same manufacturer has a great advantage: It ensures that all the parts of your smart home will be happy talking to each other (at least that’s the theory).

How smart homes work

You buy these products, install them at home, and load up the app on your phone to control them. But what’s going on behind the scenes? The common denominator in most of these devices is internet access, which allows them to receive commands and software updates. Unfortunately, not all gadget manufacturers support multiple standards, so it’s a question of reading the small print and doing as much research as possible before purchasing a device. The smart home landscape is changing pretty rapidly, which is both good and bad news for the humble consumer. It means new integrations and partnerships are constantly being added, but it also means that your device can quickly become outdated, unable to talk to anything else in your fledgling smart home. Apps like IFTTT (short for “If This Then That”) can plug some of the gaps by connecting devices and services that don’t normally communicate with each other. IFTTT lets you close your garage door on a schedule, get alerts about your Samsung washing machine, and more—but again, the number of supported devices changes on a regular basis.

Setting up a smart home

If you plan to make your own home smart, the first step is to sit down and decide what you want to be able to do: Control the lights? Beef up home security? Use voice commands to play music? Once you have a clear set of goals, pick a platform that fits most of your needs—and that you’ll feel comfortable using—and base the rest of your buying decisions around that. Alternatively, you can start small: Buy one TP-Link lightbulb, for example, and regardless of whether Alexa or Google or Apple dominates your home, you can control the bulb from TP-Link’s own app for Android or iOS. Trying to understand how all of these smart home systems can work together is a little bewildering at first, so don’t overcomplicate it if you don’t have to. Most smart home products will work independently, which means you don’t necessarily have to worry about creating some grand system where everything is compatible. The key benefit in buying devices that all work with one platform is that you can use a single hub (like an Echo) to manage everything in sync, rather than downloading dozens of apps to your phone. It’s up to you (and your budget). Thankfully, setting up most smart home devices is a breeze, and a lot of the time you’ll just need to install an app and tell your intelligent appliance what your Wi-Fi password is. After that, you can enjoy the benefits of an app-controlled lock, thermostat, or lightbulb that learns your preferences over time. With so many devices now on sale and several platforms to choose between, there isn’t a right or wrong way to get started with your smart home. The possibilities are virtually limitless, so enjoy exploring. For a more detailed dive into smart home tech, check out the hacker’s guide to smart homes.
