The Most Important Decision for Your Smart Home Is Choosing an Ecosystem.
In Lifehacker’s “Whole Home Automation Guide” series, we’ll cover all the ways to power your home with autonomous technology, room by room. Whether you want to create a smart security system, turn a dumb device into a smart one, or simply control your lighting from your phone, this guide will help you figure it out.
So, you want to create a smart home but don’t know where to start? Whether you’re building a smart home from scratch or figuring out how to set up an existing one, the good news is that it’s much less of a hassle than it used to be. Smart home technology has become significantly simpler in recent years, thanks in part to platform consolidation and standardized connectivity protocols. You simply choose your path based on the ecosystem you want to work in, and then build a set of devices based on that—for example, video intercoms, security cameras, and smart lighting. At this point, everything is pretty straightforward, so it’s important to choose the right smart home ecosystem before you get started.
The main players here are Google, Apple, and Amazon, and you’ll need to choose which one to use when determining your preferred control interface. This is because the Matter protocol, which powers most modern smart devices, is compatible with all three, so the most important thing here is the software. However, when setting up legacy devices, you’ll also occasionally encounter the Z-Wave and ZigBee protocols, so it’s important to double-check your chosen ecosystem’s support for these protocols if you have a lot of older equipment. (This usually depends less on the software than on the hubs, or, in other words, the central devices that connect your smart home devices.)
Now that all of the above is explained, let’s look at everything you need to know to choose a smart home ecosystem.
Google Home
Anyone already deeply integrated into the Google ecosystem, whether it’s an Android device, a Chromebook, or the Chrome browser, will likely find this ecosystem most convenient. The Google ecosystem is a smart home platform built entirely on the Google Home app and Google Assistant (Gemini coming soon). This means it seamlessly integrates with your Google account and other services, including Gmail, Google Photos, and YouTube, which is a huge plus for those who actively use these apps.
At the hardware/protocol level, devices like the Nest Hub smart display and the Nest Wifi Pro mesh router are equipped with Matter technology, so they will work with most modern smart home devices. They also act as Thread edge routers, as Thread is a power-efficient protocol that maintains connectivity between devices throughout the smart home. Additional smart devices with built-in Thread help extend this range, but they can also be used to extend it if you find it’s insufficient.
In terms of software, your Nest Hub smart displays and Google speakers will act as the interface for controlling your smart home. Alternatively, you can use an Android device with the “Hey Google” feature enabled for hands-free control of your smart devices. iPhone users can also connect to this ecosystem through iOS, although it uses a combination of the Google app and Google Home apps. You’ll also need an external Nest device, such as a Nest Hub or Google TV Streamer (4K) , to act as an anchor. Android users are fully integrated into the ecosystem, meaning less reliance on Google’s smart home apps, but there are ways to set up shortcuts on iOS that partially replicate this experience.
The main advantage of Google’s smart home ecosystem is its compatibility with third-party manufacturers, including lesser-known ones like Rachio, a smart sprinkler controller, and Wiz, the budget-friendly Philips Hue (Signify) line. Furthermore, Google has the most extensive experience in contextual voice commands, and the company will continue to develop this area even as Gemini takes the lead. Google claims that Gemini will deliver more natural conversations and deeper automation intelligence .
Even if you’re not a fan of voice assistants, the Google Home ecosystem also includes a powerful smart home app editor . This feature arrived later, after the launch of Matter, but it helped improve the platform’s relative customization flexibility.
Apple HomeKit
Apple HomeKit, controlled by the Apple Home app, is the preferred smart home ecosystem for those who already own an iPhone, iPad, and/or Mac. Apple uses a combination of Wi-Fi, Bluetooth, and Thread for connectivity, and smart home control requires a specific Apple device. This can include a HomePod (second generation), HomePod mini, or Apple TV 4K (second or third generation with 128GB of storage), all of which have the necessary components to function as Thread routers. It’s also worth noting that the iPhone 16 Pro functions as a Matter controller, but you’ll still need a “primary” device, such as a HomePod mini, to enable remote access, shared control within the home, automation and scheduling, and end-to-end video encryption.
As is typical in the closed world of Apple’s carefully curated but less open apps, the smart home ecosystem is built on security and efficient management. Apple is responsible for the compatibility of devices within this ecosystem, so while supporting Matter, the company also requires third-party manufacturers to undergo a rigorous MFi certification process , which stands for “Made for iPhone/iPad.” Apple maintains a list of devices certified for use with its products. If you’re already accustomed to this lifestyle, this won’t be a significant change from the current state of affairs, but it may make building a smart home with Apple more restrictive than with Google or Amazon.
However, an advantage of Apple’s smart home ecosystem is its strong focus on privacy, especially compared to those of Google and Amazon. HomeKit prioritizes local data processing , using devices like the HomePod to execute routines and commands rather than sending requests to external servers. Apple will also allow encryption of recordings from HomeKit-compatible security cameras , ensuring they are never transmitted to the company’s servers. This contrasts with Google, which still actively uses cloud servers to store video and implement advanced features like facial recognition. The Gemini smart devices coming to Google Home will also initially utilize cloud processing.
Amazon Alexa
Amazon pioneered consumer smart home products back in 2014. Since the introduction of its first smart speaker and early attempts at Alexa, Amazon’s smart home ecosystem has become the most robust and extensive option compared to Google and Apple, even if it doesn’t use the familiar interface you might be accustomed to on your Android or iOS phone.
Connection is primarily via Wi-Fi, although some Amazon Echo smart speakers and displays also function as ZigBee hubs. This energy-efficient protocol has become the de facto standard for many older smart home devices, but don’t expect it to be absent from modern devices. Therefore, Amazon fully embraced Matter from the start. Most currently available Echo devices can also function as Matter controllers and/or Thread edge routers. Alexa-compatible devices are also generally more affordable than other offerings.
Amazon’s Alexa voice assistant handles the entire process, and its companion app is what you’ll use to customize commands, set up automations, and select connected services. However, the digital assistant hasn’t seen much consumer activity in recent years, as Amazon has instead focused on fundamental improvements to its backend. We’re still waiting for Amazon to share more details about its long-term background computing strategy, dubbed Alexa+ , which is currently in early access. The idea is that Alexa will work in the background, turning on lights and adjusting the climate in your home without you having to say a word. You can sign up to try the contextual chatbot before it’s released .
Upon launch, Alexa+ will require a $20 monthly subscription if you’re not already an Amazon Prime subscriber. The “classic” version of Alexa will still be available for basic voice commands, such as playing music, setting timers, and running preset programs.
Matter: A Smart Home Connector
After explaining the three main smart home ecosystems, let’s take a closer look at their protocols. I’ve mentioned it several times already, but the most important word to know when building a smart home or upgrading an existing one is Matter . Matter is a unifying protocol that required years of coordination between major companies and trade organizations like the Consumer Standards Alliance (CSA) to become the leading standard unifying the modern smart home. It’s not an ecosystem, but rather a language that allows devices from different ecosystems to communicate with each other. Matter was introduced to address the fragmentation that was affecting smart home adoption. If you’re unsure whether your smart devices can communicate with each other, you might be hesitant to buy one altogether, which is detrimental to the entire industry.
Matter works on top of existing network protocols like Wi-Fi and Thread. It’s compatible with all major smart home ecosystems, as well as some lesser-known ones. While Matter is still in its infancy, its existence can help you avoid being locked into a specific ecosystem. This standard has also simplified setup and is more future-proof than previous generations of smart home devices.
Z-Wave and Zigbee: Old Faithful Friends
The ZigBee and Z-Wave protocols have been around for a long time, dating back to the early days of smart homes. Before Wi-Fi became a sufficient connection for low-power devices, these two protocols were the primary means of communication between them. If you were looking for smart devices that required energy efficiency, such as a motion sensor or a smart light switch, you had to use either ZigBee or Z-Wave to connect.
The Zigbee and Z-Wave protocols are designed with energy efficiency in mind, which is why many battery-powered smart devices use these protocols. Zigbee and Z-Wave also utilize a mesh network architecture, which allows each device connected to the network to act as a repeater, extending the signal’s range. This is especially useful when building smart homes in larger homes and hard-to-reach areas, such as basements and backyards.
These protocols remain highly relevant if you’re planning to build a robust, automated smart home, and are often the best connection option for battery-powered sensors and devices. Matter is simply a bridge that lets you connect all your ZigBee and Z-Wave devices into a single control app. Recently released smart home hubs, like this one from Aeotec , support both ZigBee and Z-Wave, as well as Matter and Wi-Fi.
Automation: The Best Part of a Smart Home
The beauty of a smart home is that everything from lighting to air conditioning can be scheduled and programmed without requiring prior control. Within each ecosystem, the fundamental logic of automations and routines is generally the same: they follow the principle of “if this happens, then activate this action.” In many cases, voice control isn’t required to perform these “ambient effects” throughout the home. Each ecosystem has its own name for them. Amazon calls them “routines,” while Apple and Google call them “automations.” (Google used to call them “routines,” but is now abandoning that term.) The concept remains the same across all ecosystems.
Google Home automation is relatively simple. It can be activated at a specific time of day or based on a combination of conditions. For example, you can set up a “leave home” automation based on your location. When your phone is detected outside a specified geofence, Nest cameras automatically turn on and start recording. At the same time, lights can be dimmed to a minimum level, and all doors with smart locks can be set to automatically lock. All of these settings are easily configured directly in the Google Home app. For users who need more complex logic and conditions, Google also offers an online scene editor for creating custom programs.
Apple HomeKit automations are more privacy-focused, as they are implemented on the device and use a control center, such as the HomePod mini or Apple TV 4K, for remote control. You can easily set up automations through the Apple Home app on iOS or iPadOS. Automations include triggers such as a person arriving or leaving the house, a specific time of day, the activation of a HomeKit-compatible sensor, or a change in accessory state, such as a smart light bulb turning on. Similar to Google Routines, Apple automations allow you to set up scenes, which are preset combinations of device settings and individual accessories throughout your home.
Amazon routines work similarly. They require a key trigger, whether it’s a voice command, motion detection by a sensor, or a device state like an open door. Alexa is great for controlling lights and smart plugs, playing music and podcasts on specific devices, and even sending messages to another Alexa-enabled device, whether it’s an Echo smart speaker or the Alexa app on your phone. Amazon’s Alexa routine builder has long been considered one of the most convenient solutions on the market. It remains to be seen if it maintains this status with the arrival of Alexa+.
Before Matter, choosing smart home devices had to be done carefully, as different ecosystems and brands were often incompatible. Matter was created solely to unite a fragmented market, where Apple’s HomeKit accessory didn’t work with the Google Home speaker. While Matter as a protocol isn’t responsible for automation, it allows devices to interact with a hub operating in different ecosystems. A hub, for example, allows a motion sensor from another manufacturer to control smart lighting from a different ecosystem, with Matter acting as the bridge.
How to Choose the Right Smart Home Ecosystem
Ultimately, I can’t say which smart home ecosystem is best for you, as it depends entirely on your needs and preferences. If you particularly value privacy, Apple’s HomeKit ecosystem may be just what you need, despite its higher price and limited feature set. If you’re a dedicated iPhone and Mac user, it’s also an excellent choice. The same applies to Android users who are already signed in to a Google account and integrated into the ecosystem.
If you have a smart home with multiple platforms, the best way to choose a unifying tool is to decide which voice assistant you prefer to interact with. If you like Siri and prefer commands executed directly on the device, choose HomeKit. If you’re a big Google fan and have Nest devices or even Chromecast, that’s your choice. And if you prefer the simplest interface of the three, Amazon’s Alexa remains the easiest to use.
