Home Assistant vs openHAB
Both are free/open-source alternatives to Proprietary Smart-Home Hubs. Here's how they stack up — verified facts, no spin.
Home Assistant
TOP PICKLocal-first home automation on hardware you own.
Home Assistant is the open-source home-automation platform that runs entirely on your own device — a Raspberry Pi, a mini-PC, or the purpose-built Home Assistant Green/Yellow. It integrates thousands of devices locally, so your home keeps working with the internet down and nothing phones home unless you allow 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.
