SmartThings vs Home Assistant vs Hubitat: 2026 Comparison
Why This Comparison Actually Matters Now
Three years ago, the smart home hub landscape was simpler. Samsung SmartThings was the default recommendation for anyone who didn’t want to code. Home Assistant was for enthusiasts who didn’t mind a learning curve. Hubitat existed as a niche alternative for people who cared deeply about local processing.
Samsung discontinued the SmartThings Hub hardware in late 2024, pushing the platform toward cloud dependency. Home Assistant has moved in the opposite direction — maturing from enthusiast tool to genuinely usable product. Hubitat keeps doing what it does best: running everything locally, no exceptions.
The question I hear most from readers isn’t “which is best” — it’s “which is best for me.” Those are very different questions. Let me break down what each platform actually offers, who each one is for, and where the real trade-offs lie.
The Three Contenders at a Glance
Samsung SmartThings
What it is: A cloud-centric smart home platform that was originally hardware-based (the SmartThings Hub) but has evolved into primarily a software/platform play. Samsung discontinued the dedicated SmartThings Hub hardware in late 2024 and now partners with third-party hubs that run the SmartThings platform. You can learn more at smartthings.com.
Who it’s for: People who want the broadest device compatibility with the least setup friction, and who are comfortable with cloud dependency.
Starting cost: Free (platform), $0-$299 depending on hub hardware choice
Home Assistant
What it is: An open-source smart home platform that runs on dedicated hardware (Home Assistant Green, Yellow, or any Raspberry Pi) or as a VM on existing servers. Everything runs locally by default. Visit home-assistant.io for more details.
Who it’s for: Users who want complete control over their data, deep automation capabilities, and don’t mind investing time in setup.
Starting cost: $99 (Green hub — see the Home Assistant Green product page) or free (software only on your own hardware)
Hubitat Elevation
What it is: A local-only smart home hub that prioritizes privacy, speed, and reliability over breadth of features. It runs entirely on-premises with no mandatory cloud service. Learn more at hubitat.com.
Who it’s for: Users who prioritize local processing above everything else — particularly those with privacy concerns, large installations, or reliability requirements where internet outages shouldn’t disable their lights.
Starting cost: $199 (Elevation C-8), $289 (Elevation C-8 Pro)
Protocol Support: What Actually Works With Each
This is where the practical differences become most apparent.
Zigbee and Z-Wave
Both SmartThings and Hubitat have built-in Zigbee and Z-Wave radios. Home Assistant requires an additional Zigbee dongle (the Sonoff Zigbee 3.0 Dongle Plus is popular at ~$20) and an optional Z-Wave stick (Zooz ZST10, ~$35) for Z-Wave support.
In real-world use, all three handle standard Zigbee and Z-Wave devices without issue. The meaningful difference is in edge cases:
- Hubitat has the most robust Zigbee handling for large networks (100+ devices) and tends to have the most stable Z-Wave implementation with proper mesh routing
- Home Assistant with a good Zigbee dongle matches Hubitat’s performance and exceeds it in flexibility, but requires more manual configuration
- SmartThings handles Zigbee and Z-Wave adequately for typical home networks (under 50 devices) but begins to show instability with very large mesh networks

Matter and Thread
Matter and Thread support differs enough between these platforms that it’s worth addressing separately from Zigbee and Z-Wave.
SmartThings has the most aggressive Matter integration — it can act as a Matter bridge for many existing Zigbee devices and natively supports new Matter devices. However, Samsung’s transition away from their own hub hardware means Matter support depends heavily on which third-party hub you’re using. The Aeotec SmartThings Hub (the officially partnered successor — see the Aeotec product page) handles Matter well; other implementations vary.
Home Assistant has full Matter support via the Matter integration added in 2023 and now mature in 2026. It can also run as a Thread border router (particularly on Yellow or with a Thread dongle). The key advantage: Home Assistant treats Matter devices as first-class citizens alongside native Zigbee/Z-Wave, with no artificial limitations.
Hubitat has Matter support via a beta that became stable in late 2025, but it’s more limited — Hubitat primarily acts as a Matter controller rather than a Thread border router, and not all existing Zigbee devices are bridged via Matter as seamlessly as in the other platforms.
My take: If Matter compatibility is your primary concern, SmartThings and Home Assistant both handle it well. Hubitat’s Matter support is functional but less comprehensive.
Wi-Fi and Other Protocols
All three platforms support Wi-Fi devices through their respective integrations, but this is worth noting: Wi-Fi smart home devices compete with your regular network traffic and are generally less reliable than Zigbee or Z-Wave for critical automation. If you’re building from scratch, prioritize Zigbee/Z-Wave/Matter over Wi-Fi where possible.
Matter over Wi-Fi is improving, but the protocol wasn’t designed for Wi-Fi-first deployment and still benefits from the low-power mesh protocols underneath.
Setup Experience: Honest Time Estimates
SmartThings
I tested SmartThings on the Aeotec SmartThings Hub (2024). Setup was genuinely fast — about 20 minutes from unboxing to having my first device connected and automated. The mobile app (iOS and Android) walks you through hub setup, device pairing, and your first automation with minimal jargon.
The automation builder uses a rule-based interface that’s accessible to beginners. “If this device does X, then do Y” logic is intuitive. More complex automations (multi-condition rules) are harder to build in the native app and often require the SmartThings web app or community-developed SmartApps.
Realistic setup time for a 15-device home: 2-3 hours for full installation and basic automations
Home Assistant
Home Assistant has a steeper initial climb. The official Home Assistant Green hardware setup is straightforward — plug in, install the app, wait 20 minutes for initial boot. But unlike SmartThings, you’re immediately confronted with configuration options that mean something.
The good news: Home Assistant’s “Helpers” and “Automations” UI has improved dramatically. In 2026, you can set up most automations without touching YAML. The “Devices & Services” page shows all discovered integrations cleanly.
The bad news: anything beyond basic automations benefits enormously from Home Assistant’s underlying YAML configuration. And for some integrations (particularly Z-Wave), the initial setup requires command-line comfort.
Realistic setup time for a 15-device home: 4-6 hours for basic setup, 2-3 weeks to feel genuinely comfortable with intermediate features
Hubitat
Hubitat occupies an interesting middle ground. The hub itself sets up quickly, and the device pairing process (Zigbee and Z-Wave) is straightforward and well-documented. Hubitat’s “Rule Machine” is extraordinarily powerful — it can handle complex multi-condition, multi-action automations that would require coding in Home Assistant or are simply impossible in SmartThings.
The interface is less polished than SmartThings or Home Assistant’s modern UI. It’s functional, not pretty — think “professional control panel” rather than “consumer app.” This doesn’t bother serious home automation enthusiasts but can frustrate spouses or family members who just want things to work.
Realistic setup time for a 15-device home: 3-5 hours for full setup, with steeper learning curve for Rule Machine
Automation Depth: What You Can Actually Build
This is where the differences become consequential for serious users.
SmartThings Automations
SmartThings’ native automation builder handles the common cases well:
- Device state triggers (motion detected, door opened, temperature above X)
- Time-based triggers (at sunset, at 7:00 AM, every 15 minutes)
- Simple conditional logic (if X and Y, then Z)
- Basic dimming, color, and scene control
What it struggles with:
- Variables that persist across automations (you need a workaround with virtual devices)
- Complex conditional logic with more than 3 conditions
- Devices that don’t expose their full capability set to SmartThings
- Cross-platform integrations (SmartThings → Home Assistant is possible but fragile)
For a typical home with 20-30 devices doing standard lighting, climate, and security automations, SmartThings covers 90% of what’s needed.
Home Assistant Automations
Home Assistant’s automation engine is the most capable of the three. With the combination of:
- Triggers (events that start an automation)
- Conditions (checks that must pass before the automation runs)
- Actions (what happens when triggered and conditions pass)
- Scripts (reusable sequences of actions)
- Templates (dynamic values using Jinja2 templating)
You can build automations that respond to virtually any condition in your home. Some examples I’ve built or seen in practice:
- “When front door opens after sunset and no one is home, turn on hallway lights at 30% brightness and start a 60-second timer. If door closes within 60 seconds, cancel the timer. If not, send a notification and activate the alarm.”
- “When multiple motion sensors in the living room are active simultaneously, check the global ‘Movie Mode’ variable. If active, keep lights off. If not, activate ‘Welcome Home’ scene.”
- “Monitor power draw on the washing machine via a smart plug. When power drops below 5W for 3 consecutive minutes (indicating cycle complete), send a notification, flash the kitchen light twice, and pause the living room music.”
Home Assistant can also run AppDaemon or Python Scripts for truly custom logic, which essentially turns Home Assistant into a programmable platform rather than just an automation tool.
Hubitat Automations
Hubitat’s Rule Machine deserves its reputation as one of the most powerful visual automation builders in consumer smart home software. It can handle everything in SmartThings’ native builder and significantly more.
What Hubitat does better than SmartThings:
- True local execution with no cloud dependency
- Proper variable storage and management across rules
- Device health monitoring and automated recovery (it can detect a “dead” Zigbee device and attempt to heal the network)
- Location-based triggers that work without internet (geofencing via the Hubitat app is local when configured correctly)
What Home Assistant does better than Hubitat:
- Broader integration ecosystem (thousands of integrations vs. Hubitat’s ~200 community-developed drivers)
- More flexible UI customization
- Better handling of devices that don’t follow standard protocols
For automations alone, Hubitat vs. Home Assistant is genuinely a toss-up for most users. Home Assistant wins on integration breadth. Hubitat wins on local-only reliability and the stability of its Zigbee/Z-Wave mesh.
Local vs. Cloud Processing: The Privacy Question
SmartThings processes most automations through Samsung’s cloud infrastructure. When you create an automation, your hub communicates with Samsung’s servers to execute the logic — which means your internet connection matters in ways the other two platforms don’t.
SmartThings — Primarily Cloud
This means:
- Your automations run when your internet is down — only if your specific devices and hub have local fallback configured (which varies by device)
- Your device data goes to Samsung’s servers — including device status, automation history, and location data if you use geofencing
- Latency — cloud processing adds 200-800ms to automation response times in my testing, which is noticeable for motion-triggered lighting
Samsung has improved local execution over time, and some automations do run locally on the hub. But the architecture is fundamentally cloud-first. If privacy is a primary concern, SmartThings is not the platform for you.
Home Assistant — Fully Local by Default
Home Assistant’s architecture is local-first. Unless you specifically add a cloud integration (like Nabu Casa’s Home Assistant Cloud, which is optional), all processing happens on your hardware. Your data stays on your server.
This has two significant implications:
- Your automations run even when your internet is down — as long as your Home Assistant instance is on a local network, everything works
- No subscription required — unlike SmartThings (which has subscription tiers for advanced features) and most commercial platforms, Home Assistant is free and open source forever
The privacy advantage is real. But it comes with the responsibility of maintaining your own hardware and software.
Hubitat — Fully Local, No Exceptions
Hubitat’s entire value proposition is local processing. There is no mandatory cloud service, no subscription, no data sent anywhere unless you explicitly configure cloud integrations.
This makes Hubitat the strongest choice for:
- Users in high-security environments (the paranoid option)
- Users in areas with unreliable internet
- Users who want smart home functionality that persists through internet outages
- Anyone who has read enough privacy policy fine print to be genuinely concerned
The tradeoff is that Hubitat’s user community is smaller, and its integrations are more limited than Home Assistant’s. You get privacy and reliability, but with less flexibility.
Device Ecosystem and Integration breadth
SmartThings
SmartThings has the largest official compatibility list — over 100 certified devices at any given time, with broader unofficial compatibility through community-developed SmartApps. The platform’s longevity and Samsung’s brand mean most major smart home manufacturers list SmartThings compatibility as a selling point.
The integration with Samsung’s own ecosystem (Samsung TVs, Samsung appliances, Samsung SmartCam) is deeper than what the other platforms offer.
Notable gap: Lutron Caseta and Shelly devices require workarounds or community integrations rather than native support.
Home Assistant
Home Assistant has the largest integration count of any platform — over 2,500 integrations as of early 2026. This includes devices, services, protocols, and platforms that the other two simply don’t touch.
If a device exists in the smart home space, there’s likely a Home Assistant integration for it — often multiple options ranging from “it works, barely” to “full local control with full feature support.”
The tradeoff is that integration quality varies enormously. Some integrations are rock-solid and maintained by dedicated developers; others are community efforts that break with every update. The Home Assistant community (particularly the Home Assistant subreddit and community forums) is active in flagging broken integrations and recommending alternatives.
For the genuinely curious user who wants to see what smart home technology can do, Home Assistant’s integration breadth is unmatched.
Hubitat
Hubitat’s ecosystem is smaller but thoughtfully curated. The ~200 community-developed drivers cover most major Zigbee and Z-Wave devices, popular Wi-Fi devices (Shelly, Tuya), and some proprietary ecosystems.
Hubitat’s approach is more “it just works” than Home Assistant’s “it might work depending on which driver you use.” The trade-off is flexibility for reliability.
Notable strength: Hubitat’s compatibility with Z-Wave devices is generally considered the most stable of the three platforms, particularly for older Z-Wave devices that predate the Z-Wave Plus specification.
Mobile App Experience
SmartThings App
The SmartThings mobile app (2024 redesign) is the most polished of the three. Clean interface, logical device organization, and straightforward automation builder. The app also serves as a remote control for your home — you can control devices and view cameras from anywhere without additional setup.
The main frustration: the app occasionally reorganizes device locations and scenes after updates, and the automation builder still can’t handle truly complex logic without SmartThings Labs (community) additions.
Home Assistant App
The Home Assistant mobile app (iOS and Android) is excellent for a free, open-source application. It provides full access to your Home Assistant instance, including device controls, automations, camera feeds, and the history log.
The Lovelace UI (Home Assistant’s customizable interface) translates well to mobile when configured thoughtfully. The app also supports push notifications from Home Assistant automations, which works reliably.
Where it falls short: the app requires your Home Assistant instance to be accessible (via local network or Nabu Casa cloud) for full functionality. If you’re traveling and haven’t set up remote access, you’ll need to configure a VPN or Nabu Casa subscription.
Hubitat App
Hubitat’s app is functional but unpolished. It works — you can control devices, trigger scenes, and view camera feeds. But it looks and feels like it was designed by engineers rather than product designers.
The app is reliable and fast (since everything is local), but if aesthetics and polish matter to you, it will be a constant low-grade irritant. The Hubitat community has developed alternative dashboards (Hubitat Dashboard, Hubitat Portal) that significantly improve the mobile experience, but these require additional setup.

The Honest Verdict
Choose SmartThings if: You want the smoothest experience for a standard smart home (lights, locks, thermostat, cameras) with minimal setup time, and you’re comfortable with cloud dependency. It’s the right choice for renters, new homeowners, and anyone who wants smart home functionality without becoming a hobbyist.
Choose Home Assistant if: You want to explore the full potential of smart home technology, you’re comfortable with a learning curve, you care about data privacy, and you want a platform that grows with your ambitions. The 2,500+ integrations mean you can connect almost anything. The open-source community means the platform won’t disappear when a company’s board loses interest.
Choose Hubitat if: Privacy and local processing are non-negotiable, you have a large Z-Wave network (50+ devices), and you want SmartThings-level simplicity with Home Assistant-level power but without the learning curve of YAML. Hubitat is the platform for people who want local control without becoming developers.
The Question I Get That This Article Can’t Answer
“Which hub should I buy for my home?”
I can’t answer this without knowing:
- How many devices do you have or plan to have?
- Are you renting or do you own? (Renting favors SmartThings; ownership opens Hubitat/Home Assistant options)
- How important is privacy vs. convenience to you?
- Are you comfortable troubleshooting technical issues on a forum?
- Do you have existing devices you need to integrate?
Those five questions will give you a better answer than any comparison article. Start there.
