Home Assistant vs Hubitat vs SmartThings UK 2026 — Which Platform Is Right for You?

Last updated: May 2026 | Written by someone who has used all three platforms at home

Choosing a smart home platform is one of the most consequential decisions you'll make when automating your home. Get it right and everything clicks together. Get it wrong and you're locked into an ecosystem that either costs a fortune in subscriptions, kills local control, or abandons your devices mid-life.

In 2026, three platforms dominate the conversation for UK home buyers: Home Assistant, Hubitat Elevation, and Samsung SmartThings. They're radically different in philosophy, cost, and capability.

Here's an honest breakdown — no affiliate agenda, no brand cheerleading. Just the practical reality of running these systems in a UK home.

Platform Deep Dives

Home Assistant

Home Assistant is open-source software that runs on your own hardware — typically a Raspberry Pi 4, an Intel NUC, or a dedicated Home Assistant Green or Yellow device. You install it once, it runs locally forever, and there's no subscription required.

What makes it exceptional:

  • Over 3,000 integrations — if a device exists, there's probably a Home Assistant integration for it
  • Fully local: your data never leaves your home unless you choose to expose it
  • Automations can be as simple or as complex as you want — from basic light schedules to multi-condition scripts that would defeat any commercial platform
  • Active development: multiple major releases per year
  • Huge UK community (forums, subreddit, YouTube channels)

The honest downsides:

  • The initial setup takes time. Expect a weekend to get comfortable with it
  • YAML configuration (for advanced automations) has a learning curve
  • If you want remote access, you'll need to configure a VPN, Cloudflare Tunnel, or pay for Nabu Casa (~£6.50/month) for easy remote access
  • Hardware failure means you need to restore from backup — but if you're running backups (which it does automatically), recovery is fast

Who should choose Home Assistant: Anyone who cares about privacy, wants local control, or wants to integrate cameras, NVRs, security systems, and unconventional devices. Also the right choice if you've invested in Zigbee sensors or PoE security cameras — the integrations are outstanding.

We've run Home Assistant as our primary platform for two years. See our full Home Assistant setup page and our Home Assistant pet monitoring build for real-world usage examples.

Hubitat Elevation

Hubitat is a dedicated smart home hub that runs entirely locally — no cloud required, no subscription needed. It ships as a physical hub (the Hubitat Elevation C-8 Pro is the current flagship) and connects your Zigbee and Z-Wave devices directly.

What makes it stand out:

  • Truly local: even if the internet goes down, your automations keep running
  • No cloud dependency for core functionality
  • Strong Zigbee and Z-Wave support — better Z-Wave handling than Home Assistant in some cases
  • Groovy-based apps and rules engine is powerful once you learn it
  • Long-standing stability: Hubitat doesn't chase features at the expense of reliability

The honest downsides:

  • The interface is functional but not pretty — it feels more like a networking tool than a consumer product
  • Fewer integrations than Home Assistant (though the major ones are covered)
  • The community is smaller — not a problem, but troubleshooting is slower
  • Ships from the US — expect to pay import costs/VAT on top of the £130+ base price (check Amazon UK for current availability)
  • Less active development cadence than Home Assistant

Who should choose Hubitat: Users who want local processing and reliability without the tinkering overhead of Home Assistant. If you're running Z-Wave devices specifically, Hubitat's support is excellent. Good choice for people who want to "set it and forget it" with local control.

Samsung SmartThings

SmartThings is Samsung's smart home platform — a cloud-based system with a polished app and broad device support. The hub is either built into compatible Samsung TVs/appliances or available as a standalone hub (the Aeotec SmartThings Hub is the UK-friendly option).

What makes it appealing:

  • The easiest onboarding of the three — app-driven, minimal configuration
  • Works seamlessly with Samsung TVs, washing machines, fridges, and Galaxy phones
  • Matter and Thread support built in (future-proofing for the new smart home standard)
  • Wide device compatibility for mainstream brands (Philips Hue, IKEA, etc.)
  • Regular updates from a major corporation — SmartThings isn't going away

The honest downsides:

  • Cloud-dependent: if Samsung's servers go down or connectivity drops, automations may fail
  • SmartThings has a history of feature removals and platform changes — Groovy support was killed in 2022, breaking thousands of community automations
  • Less powerful automation engine than Home Assistant or Hubitat
  • Privacy concerns: your home activity data goes through Samsung's cloud
  • Not ideal for privacy-focused users or those who want local control

Who should choose SmartThings: Users who want plug-and-play setup and already own Samsung appliances or Galaxy devices. Also reasonable if you're renting and don't want to invest heavily in infrastructure.

Head-to-Head: Key Decision Factors

Privacy & Local Control

Winner: Home Assistant or Hubitat

Both run entirely on your hardware. Home Assistant gives you the most control — you decide exactly what leaves your network. Hubitat is equally local by default.

SmartThings routes core functions through Samsung's cloud. For many people this is fine, but if you're adding cameras or security devices to your smart home, cloud routing is a genuine consideration.

Device Compatibility

Winner: Home Assistant

With 3,000+ integrations — including support for our Reolink cameras, Sonoff PoE switches, Yuanley PoE switches, and virtually every Zigbee device — Home Assistant wins outright.

Hubitat handles Zigbee and Z-Wave very well but has fewer integrations for IP cameras and cloud services. SmartThings covers mainstream brands but struggles with niche or locally-controlled devices.

Ease of Setup

Winner: SmartThings

SmartThings wins on initial experience. Open the app, scan devices, done. Home Assistant's initial setup is genuinely more involved — you're installing an OS, configuring integrations, learning the interface.

Hubitat sits in the middle: the hub auto-discovers Zigbee/Z-Wave devices, but configuration requires more reading than SmartThings.

Automation Power

Winner: Home Assistant

Home Assistant's automation engine — particularly with Node-RED or the built-in Automations editor — is the most powerful of the three. Condition logic, triggers, templates, scripts, scenes, and the ability to write custom Python or shell scripts via the command line integration.

Hubitat's Rules Machine is genuinely powerful and gives Home Assistant a run for complex logic. SmartThings automations are straightforward but hit a ceiling quickly.

Long-Term Cost

Winner: Home Assistant or Hubitat (tie)

Home Assistant: hardware once (£60–£150), software free. Optional Nabu Casa remote access at £6.50/month but not required.

Hubitat: hub once (~£130+), no ongoing costs.

SmartThings: currently free for core features, but Samsung has changed pricing before. No guarantees on what costs in 3 years.

FAQ

Is Home Assistant free?

The software is completely free and open-source. You pay for the hardware it runs on — a Raspberry Pi 4 (£60), Home Assistant Green (£90), or any old PC or NUC. The optional Nabu Casa cloud subscription (£6.50/month) adds easy remote access but isn't required.

Does Hubitat work in the UK?

Yes. The Hubitat Elevation C-8 Pro works with UK Zigbee and Z-Wave frequencies. Check Amazon UK for availability — import costs can add £20–£40 when ordering from the US directly.

Can SmartThings work without internet?

Partially. Some local automations work offline, but cloud-dependent integrations and remote access require connectivity. It's not a fully local platform.

Which platform works best with Zigbee sensors?

Home Assistant with a Zigbee coordinator (ConBee II, Sonoff Zigbee Dongle Plus) via ZHA or Zigbee2MQTT is the most compatible and configurable option. Hubitat also handles Zigbee very well natively. See our best Zigbee sensors UK article for compatible device recommendations.

Which platform should I choose for PoE cameras?

Home Assistant — it has native Reolink integration, ONVIF support for Hikvision and others, and can display camera feeds directly in its dashboard. We cover this in detail in our best PoE cameras UK article.

Is SmartThings being discontinued?

No — SmartThings is a core Samsung product line. However, they have removed features and deprecated APIs before (Groovy in 2022), so long-term stability requires trusting Samsung's product decisions.

The Verdict

Choose Home Assistant if: You want maximum control, the best device compatibility, local processing, and you're willing to invest a weekend learning the platform. It's the most powerful option and the best long-term bet for a privacy-focused home.

Choose Hubitat if: You want local processing and reliability without as much tinkering as Home Assistant. Particularly good for Z-Wave-heavy setups.

Choose SmartThings if: You want the simplest possible setup, you have Samsung appliances, and you don't care deeply about local control or privacy.

For most UK users building a serious smart home — especially those adding security cameras, smart locks, smart plugs, and automation sensors — Home Assistant is the right choice. The learning curve is real but the ceiling is unlimited.
