Best smart home systems in 2024: Reviews and buying advice

A true smart home has never been easier to achieve, and the gear needed to get there has never been less expensive. We have other roundups that name the best smart home components–everything from the best smart bulbs to the best smart speakers–but in this story, we name the best hubs that link all those devices together.

While the lines are becoming increasingly blurred, we see two basic types of smart home systems: Those focused on convenience first and those focused on home security first. You might be able to expand a smart home system to include elements of home security, and you might be able to expand a home security system to control convenience features like smart lighting. But decide your primary goal–convenience or security–first and shop accordingly.

Updated April 23, 2024: We’ve added a link to our news story covering SimpliSafe’s announcement that it will begin using a combination of AI and human monitors to track trespassers who might pose a threat to its subscribers’ homes. Artificial Intelligence will monitor the live feeds from SimpliSafe’s outdoor cameras and flag suspicious activity outside the home. From there, human monitors will take over and use the camera’s two-way audio feature to warn the trespassers to leave the area, dispatching police if they don’t leave or if the situation escalates.

The best smart home systems

What to look for when shopping for a DIY smart home system

As we mentioned earlier, smart home systems come in a dazzling array of shapes and sizes, from brain-dead simple to vastly complex. Features vary just as widely, so you’ll need to pay more attention than usual when you’re narrowing down the field to find the product that’s right for you. Here’s a look at some of those key decision factors. To see how each system on the market measures up to those promises, drill down into our reviews.

Device support

Some smart hubs–SimpliSafe, for example–only support their own accessories, though they might support Amazon Alexa or Google Assistant for voice control. Other systems–such as the Ring Alarm family–offer certification programs for third-party devices. They might also offer hooks into systems developed by third parties: Amazon (Alexa smart speakers and displays), Apple (HomeKit and Siri), Google (Google Home speakers and displays as well as Nest thermostats, cameras, and smoke/CO detectors), are the biggies here.

You should also consider whatever smart devices are already in your home. Do you want to use them with the new system you’re buying? If the hub doesn’t support them, you might be looking at a massive upgrade cycle to replace them. As well, you need to think about what devices you plan to add to your system down the line.

IFTTT support

Many top smart home systems support IFTTT (If This Then That), a simple scripting system that lets you connect devices that otherwise wouldn’t be compatible. For example, you could use IFTTT to turn all the lights in the house blue if a water leak is detected by your smart hub—even if it can’t speak directly to the lighting system itself.

Wired vs. wireless hub connection

Many smart hubs must connect to your wireless router via an ethernet cable, which limits their placement and, of course, requires a free ethernet port on your router or switch. That can be an issue with puck-shaped routers that have just two ethernet ports–you’ll need to buy an ethernet switch to have enough ports. A smaller number of hubs are wireless and can be placed anywhere in range of the router, increasing your flexibility.

Sensor range

If your home is large or spread out, you’ll need to pay attention to the range that the hub’s sensors support. Hubs may support a wide array of connection protocols, including Bluetooth, Wi-Fi, Z-Wave, and Zigbee, all of which have very different ranges. As with a wireless router, smart hub range can also be impacted by interference and device placement, and smart home devices themselves have different specs, as well. Take the time to look into the detailed specs to be sure sensors and third-party devices will work with your home’s infrastructure.

Battery backup

If the power goes out, your smart lights won’t be useful anyway; but other smart home features, like security sensors, rely on a hub that’s always powered on. Some smart home smart hubs feature battery backups (thanks tol rechargeable or disposable cells). Even a short power outage can cause a significant delay while the hub reconnects, so a battery backup makes sense in many home environments. If you like everything else about a particular hub that lacks a battery backup option, consider investing in an uninterruptible power supply to plug it into.

Mobile app usability

You’ll probably be interacting with your hub primarily through its mobile app, so you’ll want one that’s intuitive and powerful, with all the key features you use front and center. App-store screen shots and, of course, our reviews can help you get a sense of what you’re dealing with on the app side of things.

Overall complexity

This is a companion consideration to the mobile app, relating primarily to the audience for whom the smart home system was developed. Is the system geared toward everyday users with limited customization needs? Or is it built with extreme flexibility in mind, to the point where the configuration decisions might overwhelm a novice user? Again, close attention to our reviews can help you gauge how comfortable you’re likely to feel with any system.

What to look for when shopping for a DIY home security system

The factors listed above are equally important when shopping for a home security system, but you should also consider these additional factors.

Sensor support

A companion consideration to the device support issue above, if you’re in the market for a DIY home security system, you’ll want one that supports all the sensors you need. Most security hubs only work with the sensors made by the same manufacturer, so you can’t mix and match as you would with a general-use smart home hub. Some security systems offer only a very narrow range of sensor types, while others have a wide variety to choose from. You’ll want motion and door/window sensors at a minimum. For added security, consider buying freeze, water leak, humidity, smoke and/or carbon monoxide sensors, garage-door, and glass-break sensors. Make sure the smart home hub you buy supports all the sensor types you wish to deploy.

Cellular radio and battery backup

A security system that can be knocked out of commission by simply disabling your broadband connection doesn’t provide much protection. The best systems will include a cellular backup module that kicks in when your usual broadband connection drops. You should also carefully consider the battery backup consideration above, which is essential for dealing with power outages and is a standard feature on most security-focused hubs.

Professional monitoring

If you don’t want to monitor your own security system 24/7, you’ll at least want the option to engage with a professional security company that can keep tabs on it for you when you’re out on walkabout. These invariably cost extra, which leads to our final consideration….

Service plan costs

Service plan costs vary widely from system to system, and many vendors offer a range of plans to choose from. Some systems will work without a service plan at all, allowing you to self-monitor. Some require a plan to function at all. Also note that lower-tier service plans might provide only cloud storage for your security cameras. Wyze Labs offers one of the least-expensive plans: $9.99 per month with no long-term commitment, or $99.99 for a full year. Price out service plans carefully, taking the overall quality of the system into account, before you pull the trigger.

Other notable smart home systems we’ve reviewed

We’ve evaluated lots of other DIY smart home systems. If none of our top picks check all the boxes for you, take a look at these other products.

• Abode Smart Security Kit is virtually the same as the Abode Iota Security Kit, with the key difference being the integrated security camera integrated into the latter product. Both packages use the same accessories and sensors and support the same monitoring plans.
• Aqara Hub E1 is very similar to Aqara’s Hub M2 system, except it plugs into a USB power adapter and doesn’t have its stablemate’s infrared blaster feature. And like the Hub M2, the Hub E1 controls only Aqara Zigbee devices.
• Aqara Hub M2 is mostly about the convenience aspects of the smart home. It’s very easy to set up, but that ease of use is largely attributable to how it limits you to using only Aqara’s own devices.
• Arlo Home Security System is strictly a home security system, and it features sophisticated sensors that can do a lot more than detect open or closed states. But it’s largely a walled garden in that you can only use Arlo products with it.
• Ecobee takes an interesting approach to home security, integrating its smart home hub into the company’s top-shelf smart thermostat. Ecobee also has a great home security camera, and the entire system is HomeKit compatible.
• Homey Bridge is a SmartThings-like smart home hub that supports Wi-Fi, Zigbee, Z-Wave, Bluetooth, 433MHz, and infrared devices. Like SmartThings, it’s focused primarily on convenience versus home security. But you’re limited to just five devices unless you pay for a subscription.
• Hubitat Elevation (model C7) is a powerful smart home hub favored by many hardcore enthusiasts, and unlike the Aeotec Smart Home Hub we like so much, Hubitat’s product isn’t reliant on a connection to the internet. Less-experienced users, however, will encounter a steep learning curve.
• Minut Smart Home Alarm is uniquely suited to rental properties, including Airbnb units. It emphasizes privacy by monitoring only your home’s temperature, humidity, volume level, and air pressure, sending alerts only when thresholds are exceeded.
• Notion is a smart home system with unique one-piece sensors that can do everything from determine if a door or window is open or closed to alert you to the presence of water where it shouldn’t be. Professional monitorings is available, too, for just $10 per month. But this is a smart security system, you can’t control lights and other systems in your home.
• Tapo H100 Smart Hub is a budget-priced home security that’s compatible with a very limited number of security products from the same manufacturer, and it doesn’t support security cameras at all. It’s main attraction is its low price tag.
• Roku Home Monitoring SE is yet another low-priced home security system, but with a twist: Roku sources this system from Wyze Labs and puts the Roku brand on it. Affordable professional monitoring is available.
• SwitchBot Hub 2 is primarily a gateway for other SwitchBot smart home products, but it can also serve as a Matter bridge for a host of third-party products.
• Wyze Home Monitoring is the same system as the Roku Home Monitoring SE, but Wyze manufactures both products. This is a low-cost security system with an extremely affordable professional monitoring subscription.
