Home Assistant vs SmartThings vs Hubitat: Best Hub 2026?

Your smart home is only as good as the brain running it. Individual devices — bulbs, locks, sensors, thermostats — are easy to buy. Getting them to work together, reliably, in automations that actually make life easier, is the job of a hub. Pick the wrong hub and you will spend weekends troubleshooting. Pick the right one and your home mostly takes care of itself.

This guide compares the three hub platforms experienced smart home owners talk about most: Home Assistant, SmartThings, and Hubitat. Written for a US audience setting up or upgrading a smart home, it covers ease of use, local control, device support, and cost in general terms — and is honest about who each platform is not for.

One important distinction first: a hub is not the same thing as a voice assistant. Google Home, Alexa, and HomeKit are the ways you talk to your home; a hub is the system that connects your devices and runs your automations. The two often work together, and if you are still deciding on a voice assistant, our Google Home vs Alexa vs HomeKit comparison covers that choice separately.

What a Hub Actually Does

A hub is the central coordinator of your smart home. It speaks the wireless languages your devices use — Zigbee, Z-Wave, and increasingly Thread — and it runs the rules you set: turn on the porch light at sunset, lock the doors at 10 p.m., or send an alert if a leak sensor detects water.

Without a hub, each device lives in its own app and cross-brand automations are limited or impossible. With one, a door sensor from one brand can trigger a bulb from another, and a single dashboard shows your whole home.

Hubs differ in three ways that matter most. First, where automations run: locally on a device in your home, or in the cloud on a company’s servers. Local processing keeps working when your internet goes down and usually responds faster. Second, how much technical comfort they demand: some hubs are designed to be set up in an afternoon, while others reward patience with far more power. Third, how they handle device support: some work with almost anything, while others depend on official integrations for each brand.

Home Assistant: The Most Powerful, and the Most Demanding

Home Assistant is open-source software that runs on a small computer in your home — commonly a Raspberry Pi, a mini PC, or a dedicated device sold for the purpose. It is free software, although you will need hardware to run it on, and that hardware is a real cost to factor in.

Its greatest strength is breadth and control. Home Assistant supports an enormous range of devices and brands, including many that other platforms do not support at all, thanks to a large community that builds and maintains integrations. Automations can be as simple as a time-based light schedule or as complex as a multi-condition routine that checks the weather, the time, who is home, and whether the alarm is set. Almost everything runs locally, so your automations keep working without an internet connection, and your device data stays in your home rather than on a company’s servers.

The honest trade-off is effort. It has become much friendlier, with a visual automation editor and polished dashboard, but it still expects comfort with concepts like integrations and occasional troubleshooting, and updates sometimes need attention. If you enjoy tinkering, that is a feature; if you want set-and-forget, it can feel like a never-ending hobby.

Home Assistant is the right choice if you want the most powerful, private, locally controlled smart home available, you have a large or mixed collection of devices, and you are willing to invest time in learning the system.

SmartThings: The Easiest Starting Point

SmartThings, made by Samsung, is the most beginner-friendly of the three. Built around an app, it long required a dedicated hub; newer versions can also run on compatible Samsung devices and some smart TVs and appliances, lowering the starting cost for people already in that ecosystem.

Its strength is simplicity: adding devices is usually straightforward, the app is polished, and popular brands tend to have official support. For a first smart home, SmartThings gets you running faster than either rival, with less documentation to read.

The trade-offs are dependence and depth. SmartThings has historically relied heavily on the cloud, so some automations can slow down or stop during an internet outage, although Samsung has been moving more processing locally — check the current behavior of any device you plan to rely on. It is also less flexible for unusual devices: if a brand lacks an official integration, your options are narrower than with Home Assistant. And as a Samsung product, its long-term direction is set by Samsung, not by a community.

SmartThings is the right choice if you want the gentlest learning curve, you have a modest number of mainstream devices, and you value a polished app over deep customization.

Hubitat: The Local-First Middle Ground

Hubitat occupies the middle ground, and that is exactly why many experienced owners recommend it. Like Home Assistant, it runs automations locally, so lights, locks, and routines keep working when the internet goes down. Like SmartThings, it was designed to be approachable, with built-in apps for common automation patterns.

Hubitat supports both Zigbee and Z-Wave devices directly, and it has a reputation for handling complex automations well — including rule-based logic that goes beyond simple “if this, then that” routines. Its community is smaller than Home Assistant’s but active, and it produces custom drivers and apps that extend support to many devices.

The trade-offs are polish and breadth. Hubitat’s interface is functional rather than beautiful and can feel dated next to its rivals. Device support, while broad, is not as vast as Home Assistant’s, so an unusual device may need a community driver — or may not be supported yet. It costs more upfront than SmartThings’ app-first approach, since you buy a dedicated hub, though no subscription is required for core features.

Hubitat is the right choice if local control matters to you, you want strong automation without the learning curve of Home Assistant, and you are comfortable with an interface that prioritizes function over looks.

Side-by-Side Comparison

Feature	Home Assistant	SmartThings	Hubitat
Ease of setup	Steepest learning curve	Easiest	Moderate
Local processing	Yes, almost everything	Mixed — improving, check per device	Yes, automations run locally
Device support	Widest, community-driven	Broad, mainly official integrations	Broad, Zigbee + Z-Wave built in
Automation depth	Deepest, most flexible	Good for common routines	Strong, rule-based logic
Interface polish	Excellent dashboards, technical setup	Most polished app	Functional, less polished
Cost model	Free software; you buy the hardware	Hub or compatible device; no required subscription for core use	Dedicated hub purchase; no required subscription for core use
Privacy	Data stays in your home	Cloud account required	Local-first, cloud optional
Best for	Enthusiasts, large mixed systems	Beginners, mainstream devices	Local control without deep tinkering

Prices change over time, so verify current costs before buying. The pattern, however, has been stable for years: Home Assistant trades ease for power, SmartThings trades power for ease, and Hubitat tries to give you most of both.

Cost in General Terms

Comparing hubs by sticker price alone is misleading. Home Assistant’s software is free, yet you must buy and maintain a small computer, and possibly radios for Zigbee and Z-Wave. SmartThings can be cheapest if you already own a compatible Samsung device, while Hubitat’s cost is concentrated in the hub itself.

None of the three requires a monthly subscription for core hub features — a meaningful difference from many security and camera systems. Watch for extras instead: cloud backups, optional premium features, or voice-assistant subscriptions are separate from the hub itself.

If keeping ongoing costs at zero matters to you, that instinct connects with a wider approach to the smart home. Our guide to security systems with no monthly fee and our guide to video doorbells without a subscription follow the same principle: buy the hardware, skip the monthly bill.

Which Hub Should You Choose?

Use this decision framework:

Choose Home Assistant if: you enjoy learning systems, you have — or plan to have — a large, mixed collection of devices, local control and privacy are top priorities, and you are comfortable troubleshooting occasionally. It is the most capable option and the most demanding one.

Choose SmartThings if: you are new to smart homes, you have a modest number of mainstream devices, and you want to be up and running quickly with a polished app. Accept that some things will depend on the cloud, and that unusual devices may not be supported.

Choose Hubitat if: local control matters to you but Home Assistant sounds like too much work, you want strong automations without a steep learning curve, and you do not mind a plain interface. It is the best compromise for many households.

Consider your devices first. Before choosing a hub, list the devices you already own and the ones you plan to buy. Check each platform’s compatibility for those specific devices — especially locks, thermostats, and anything using Zigbee or Z-Wave. A hub that does not support your door lock is the wrong hub, no matter how good its reviews are.

Consider who else lives in your home. A system only you can operate breaks when you are away. Favor the platform your family or housemates can understand: simple app controls, voice commands, and physical switches that still work when automation does not.

Switching Hubs Later: What to Know

People do switch hubs, and it is rarely as simple as moving an app. Zigbee and Z-Wave devices must be unpaired from the old hub and paired with the new one, which can mean walking around the house resetting each device. Automations must be rebuilt, because each platform stores rules differently. Dashboards must be recreated.

That is why the choice matters upfront — but it is not a life sentence. You can migrate gradually, one room at a time, keeping the old hub running until the new system covers everything.

Common Mistakes

The most common mistake is buying a hub before knowing which devices it must support. The second is assuming “works with” a voice assistant means “works with” a hub — those are different claims. The third is over-automating on day one: start with two or three routines that solve real annoyances, and add complexity only when the basics are reliable. Finally, do not forget physical controls — a home where the only way to turn on a light is a phone app will frustrate everyone the first time the network hiccups.

Frequently Asked Questions

Do I need a hub at all?

Not necessarily. If all your devices use Wi-Fi and your automations live inside one brand’s app or your voice assistant’s routines, you may not need a separate hub. A hub becomes valuable when you have devices from multiple brands, devices using Zigbee, Z-Wave, or Thread, or automations that need to keep working without the internet.

Can I use more than one hub?

Yes, and many households do — a primary hub for most devices plus a secondary system for a specific brand. It adds complexity, so pick one main hub and add others only for a clear reason.

Does Home Assistant require programming?

No. Most everyday automations can be built with its visual editor, without writing code; advanced logic is optional. That said, Home Assistant still expects more technical comfort than SmartThings or Hubitat.

Will my devices work if the internet goes down?

It depends on the hub and the device. Hubitat and Home Assistant run automations locally, so local routines generally keep working. SmartThings has moved more processing locally, but some devices still depend on the cloud — check the specific devices you rely on.

Is there a monthly fee for these hubs?

None of the three charges a required monthly subscription for core hub features. Optional services, such as cloud backups or remote-access conveniences, may cost extra, and they are separate from the hub itself. Always check current terms before buying, since pricing models can change.

Which hub is best for renters?

Renters usually benefit most from the simplest option that supports their devices, since they cannot rewire or install permanent hardware. SmartThings is often the easiest starting point, while Hubitat is a good step up if local control matters. Home Assistant makes sense for renters too if they enjoy the technical side — the hub itself is portable and moves with you.
