openHAB vs Hubitat Elevation
Both are alternatives to Proprietary Smart-Home Hubs. Here's how they stack up — verified facts, no spin.
Also searched as Hubitat Elevation vs openHAB — same comparison, one verdict.
openHAB is open source (EPL-2.0) and Hubitat Elevation is not (Proprietary (paid hardware)) — so the real question is whether you want to own the smart home stack or rent it.
openHAB
Vendor-neutral, local home automation from the Eclipse Foundation.
openHAB is a Java-based, open-source automation platform that runs locally and integrates a wide range of technologies behind a vendor-neutral abstraction, so your rules aren't tied to any one manufacturer's cloud.
Hubitat Elevation
A local-processing hub for people who don't want to tinker.
Hubitat Elevation is a commercial smart-home hub that processes automations locally on the device rather than in the cloud. It is not open-source, but it keeps your home running offline and free of subscriptions — a middle ground between a closed cloud ecosystem and full DIY.

| License | EPL-2.0 | Proprietary (paid hardware) |
| Pricing | Free / open-source | One-time hardware purchase; no required subscription |
| RAM to run it wellThe figure that actually matters, not the vendor's minimum. | 2 GB — the JVM is the floor | Nothing to provision; the hub is the whole system. You only need a browser on your phone or laptop to reach the hub's local web interface |
| Realistic running costWhat the box costs each month if you run it yourself. | $0 on hardware you own | $184.95 one-off for the C-8 Pro (Zigbee, Z-Wave, Matter) or $249.95 for the Thread special edition, which drops Zigbee; no hosting bill. Optional yearly services: Cloud Backup $25/yr, Hub Protect $45/yr (as announced by Hubitat staff in April 2025) |
| Setup timeHonest first-install estimate, not the marketing quickstart. | 3 hours; the concepts take longer than the install | An hour to register the hub and pair the first devices; a weekend to rebuild a whole house's automations |
| Ongoing maintenanceThe part nobody budgets for. | Moderate. Major versions have historically required configuration migration. | Hubitat never pushes updates. You check for and install platform updates yourself from Settings, downloading a backup before each one. Shut the hub down and reboot it from the menu, never by pulling the plug. |

Which one fits you
The trade-offs above, turned into a decision. Find the line that describes your team.
Choose openHAB
if you want the source and the option to fork it, and runs locally, vendor-neutral.
Choose Hubitat Elevation
if local processing, works offline.
Neither, yet
if both carry a real cost you should weigh first — rule syntax has a learning curve, and closed-source platform. If either of those is a dealbreaker for your team, the shortlist is wrong rather than the choice.
What it takes to run these yourself
Real requirements and honest running costs, not the vendor quickstart.
Self-hosting openHAB
2 GB — the JVM is the floor RAM · 3 hours; the concepts take longer than the install
$0 on hardware you own
Self-hosting Hubitat Elevation

openHAB vs Hubitat Elevation — common questions
Is openHAB a better fit than Hubitat Elevation for smart home?
It depends on what you are optimising for, and the honest split is this: openHAB scores 88 to Hubitat Elevation's 70 on data ownership and exit cost, so it is the safer choice if you care about being able to leave. Hubitat Elevation earns its place on a different axis — local processing, works offline. Neither is a wrong answer for every team; the table above is the actual comparison.
What happens if we want to switch later?
openHAB keeps its data local or in open formats, so leaving is an export rather than a negotiation. Hubitat Elevation is still self-hostable, so the files stay on your server either way — but it is not local-first by design, so check what its export produces before you rely on it.
Is openHAB free?
openHAB: Free / open-source. The other side of this comparison, Hubitat Elevation, is priced as One-time hardware purchase; no required subscription. "Free" here means no licence fee — if you self-host it you still pay for the server, and the running cost row above is our honest estimate of that.
Can I self-host openHAB or Hubitat Elevation?
Both can be self-hosted. The difference is what it costs you in time rather than whether it is possible — see the setup and maintenance rows above.
Are openHAB and Hubitat Elevation both alternatives to Proprietary Smart-Home Hubs?
Yes — both appear in our Proprietary Smart-Home Hubs comparison, which is why they are worth putting side by side. People usually arrive here already having decided to move off Proprietary Smart-Home Hubs and now choosing between the two replacements, which is a narrower and much easier question.
