The 6 best home automation systems: Put your home on auto-pilot

The thing with home automation systems is that it's important to find one that suits your needs, that is user-friendly to your abilities, and that has good compatibility with the brands or devices you want to stick with. SmartThings has all of that.

User interface

SmartThings is the best home automation system because, aside from high support among brands, it features very easy and straightforward navigation through the app. 

The navigation on the SmartThings mobile application is highly intuitive: Any favorite devices, scenes and automations appear as cards right on the app's home screen, with options to add more devices just a tap of a finger away. Editing, adding and removing automations is also readily available from a menu at the bottom of the screen.

The SmartThings application comes with all Galaxy phones, but is also available on the Google Play store and the App Store for Apple users. 

Compatibility

SmartThings is probably the platform that offers the most support for smart devices on the market. With Wi-Fi, Zigbee, and Z-Wave protocols built into the Aeotec hub, you'll have hundreds of brands and over 5,000 smart devices already on the market to choose from. 

Created by Samsung, you can also add smart Samsung devices to your smart home through SmartThings, to let you see how long you have to go on your washer and dryer or dishwasher right from your mobile device. 

There's home automation systems out there that let you add devices and enjoy some capabilities right from their app, but SmartThings makes it simpler to use these devices to their full potential. Where some systems may offer an on/off switch on the app when you add a smart light, SmartThings lets users control brightness, light color, and white temperature, for example. 

You can also add voice control with SmartThings, with the ability to add Google Assistant and Amazon Alexa right on the app.

Pros:

• Most support across brands
• Intuitive user interaction on app 

Cons:

• Not compatible with Siri

Home Assistant is an open-source system that lets users control their smart home in a very intuitive manner. The biggest highlight for Home Assistant is that you don't need to buy a hub to use it. You can run Home Assistant on Windows, MacOS, Linux, ODROID, the ASUS Tinkerboard, or a Raspberry Pi. That last one being the most common option due to its low energy consumption.

HA runs locally, only pulling data from the cloud when there is no other choice, making it snappier, more responsive, and secure than other systems.

Setup

Home Assistant has a reputation of needing a lot of tinkering to work, thus it was mostly used by the tech-savvy crowd. But they've simplified their UI and have made it easier for the average smart home enthusiast to come on board. Figuring out how you're going to run Home Assistant and what device you're going to use for it is the hardest part. 

After you download it on your computer, you just need to set it up, which is the fun part. Setup involves adding your location, choosing an administrator, and your preferences. HA will then discover the devices and services on your network and let you add them to your configuration

Then all that is left is becoming familiar with the web interface. Home Assistant is actually one of the fastest and most responsive home automation systems on the market with high automation power and compatibility. 

Compatibility

Home Assistant integrates with over 1000 different APIs; it'll work locally, over the cloud, via Zigbee and Z-Wave, via Bluetooth, and, coming soon, with Matter.

As far as support for voice control, you can add Amazon Alexa and Google Assistant to command your smart home. And though Home Assistant runs on a local server, you can also download a mobile app as a companion and to control your devices and get alerts.

Pros:

• No need to buy hub

• Fast response time

• More secure than the cloud

Cons: 

• Not as user-friendly as others

HomeKit is Apple's option for smart home automation systems. A HomePod mini or an Apple TV 4K both double as a hub for HomeKit, which is pretty nifty considering you're getting two uses from one device. 

The HomeKit mobile application is reminiscent of the SmartThings app in its visual outline but I'd say with a simpler design to make it more user-friendly. Devices appear on the application as cards, with your favorite accessories and a preview of your favorite camera feed accessible from the app's home. 

Shortcuts appear at the top of the page, with buttons to access your security system, see what devices are running, and any accessories that aren't responding.

I've had a pretty good experience overall with Apple's Home app, though I do find some bugs now and then and some things that could be streamlined, like an easier way to see all rooms in one page. Though the app can leave a user wanting at times, Apple did announce some major updates to the Home app coming this fall.

Automation power

HomeKit has improved its automation power in recent years. Automations are easily added in the Home app, which walks you through how to customize them. You can have different triggers for automations, like when someone leaves or arrives, a time of day, an accessory is controlled or a sensor detects something. 

A drawback with this system's available automations is that HomeKit won't run automations that involve unlocking a door when you arrive home, for example, without first confirming it on your phone. This is part of Apple's safeguarding of its users' security, but it means that if you want to unlock your smart lock when you get home automatically, you'll have to open the app each time you arrive to confirm this action and then it'll run. Kind of takes the auto out of automation.

There are some unofficial workarounds though. 

Compatibility and support

Because Apple is more strict in their data security and consumer privacy policies, there aren't as many smart devices that can cross the compatibility threshold to HomeKit as there are for other systems.

HomeKit is limited to devices that are certified to work with HomeKit, so just because an item is labeled as smart, it won't necessarily be compatible with it. It's important to always look for that label in a device you'd like to buy for your Apple smart home ecosystem. 

With HomeKit, you'll be able to control your smart home from your iPhone, iPad, or even your Apple Watch, making this the absolute best home automation system for Apple users.

Pros:

• User-friendly app

Cons:

• Low support

• No geofencing to unlock doors automatically

So voice control is a huge deal in home automation. You want to feel like a high baller when you walk in and have a robot assistant waiting on you 24/7, right? Well, 2022 isn't there yet so the current smart assistants on the market are the next best thing. 

Having tried Google, Alexa, and Siri, I can tell you that for voice control fans, the right voice assistant can make or break your smart home. Personally, I find Alexa to be the most accurate in her responses and understanding my commands, Google is probably middle of the road, and Siri still plays Sweet Caroline when I ask her to turn on the downstairs lights.

Now, Alexa isn't perfect, we know that. But she is a favorite for smart homes and going the Amazon Alexa route ensures vast compatibility, as it's the most popular voice assistant out there.

Setting up the Amazon Alexa app is pretty easy, the platform is built around Alexa, and you can easily add devices and customize your home. And with Amazon's Frustration-Free Setup, setting up new devices will become even easier with fewer steps. 

I do wish that some things like routines and your devices were more easily accessible on the Alexa App. Though they are both available on the app's home, I find myself getting distracted by all of Alexa's suggestions. And, to be honest, the app just isn't the easiest to navigate in the beginning. You get used to it, however, and learn to easily make your way around it, but it shouldn't have to take as long as it does to reach that point.

Connectivity and automations

Alexa is available on multiple Amazon devices, like the Echo speakers and Fire TV devices. It works through Wifi, Bluetooth, Zigbee (on Echo 4th Gen, Echo Show except 1st Gen, and Echo Studio) and, more recently, Matter.

The Alexa app has some pretty good automation power. Amazon is set on making America's voice assistant out of Alexa, so they've put quite a lot of effort in making sure she helps optimize productivity, routines, shopping, your access to information and current events, and how you cook and enjoy your music. 

An Echo device, either a speaker or display, will give you access to thousands of skills and dozens of available routines to make the most of all your smart devices. You can set your Echo to detect a barking dog and have Alexa either play soothing music or let you drop in to soothe them. Alexa can even turn off a light when it hears snoring in the room, how creepy is that? Cool, I meant cool.

There are countless ways to take advantage of Alexa's automation power and, with popularity still pretty high, more are turning up every day. 

Pros:

• Alexa is responsive and smarter than others
• Everything works with Alexa

Cons:

• App isn't as user-friendly

Many smart home users have adapted the Google ecosystem for their home control. This is no surprise when you consider the Nest Thermostat was a groundbreaking device in the internet of things.

Google grabbed the Nest name and ran with it, making an entire line of smart home gadgets to fulfill customers needs. This makes it easier for Google users with a Nest thermostat to add a Nest x Yale Lock, a Chromecast, and a Nest Hub or Nest Mini to round out their homes.

The Google Home app is actually one of the best ones among home automation systems. It's easy to navigate and highly intuitive, with the application's home giving you a view of everything connected to Google Home, so you can easily go to different categories or favorite rooms.

Creating automations is actually pretty easy through Google Home. You have the starters, which work as the triggers for the automation, and then the actions that happen as a result of the trigger. You can create automations for when you arrive home or with a phrase for a trigger, for example, or my personal favorite, "Hey Google, let's cook" to turn on the kitchen lights, fan, and play the news in the kitchen. 

Support

The Google ecosystem has been relatively exclusive to other brands since its beginnings, however, the amount of available smart devices compatible with Google Home will soon explode with the launch of Matter. Coming in the fall of 2022, Matter is a new connectivity standard over IP that is being developed and is backed by major players in technology: Google, Amazon, Apple, Zigbee Alliance, and more. 

Google is expecting to integrate Matter-supported devices with their current Google Home devices seamlessly. So although there aren't a ton of compatible devices on the market right now, Google will hopefully see a change in that in the coming months.

Pros:

• Great user interface 
• Reliable voice assistant
• Strong automation power

Cons:

• Not much support with other brands yet

Are you a fan of automations that go beyond your home? IFTTT is based on the "If this, then that" programming axiom and it has become a popular option for many smart home users. 

You don't need a hub to adopt IFTTT in your home, you can simply download it on your Apple or Android phone and register for an account. Pronounced "ift", IFTTT combines services into applets, aka automations, and you can choose from different ones already available in their library. 

Though a popular application is to make your apps and accounts on your mobile device communicate with each other to carry out automations, it's also useful for smart home devices. Admittedly, you can't just buy a smart bulb and connect it to IFTTT, but it is an automation system in the literal sense.

If you have smart home devices in your home and are looking to automate them in more ways than your home allows, IFTTT can help. You can add simple automations like turning on a light at sunset, or add automations that go beyond your smart home staples, like automatically turning on push notifications when you leave home. 

Though you don't need to buy a hub to use IFTTT, nothing is free in life: they offer subscription-based plans to use their applets. Here's how those plans stack up:

• Free: up to five applets
• Pro ($2.50/month): Up to 20 applets, faster speeds, multi-action applets
• Pro+ ($5/month): Unlimited applets, faster speeds, multiple accounts, developer tools

Pros:

• Add automations beyond smart home
• Easy to use application

Cons:

• Subscription required for some options
