With 3,500+ integrations covering everything from lights and thermostats to security cameras and energy monitoring, it runs on a Raspberry Pi or dedicated hardware inside your home.
Automations trigger on time, location, sensor state, or any combination using a visual editor or YAML.

The built-in Assist voice engine processes commands locally without routing speech to external servers.

Home Assistant is governed by the Open Home Foundation, a non-profit based in Switzerland, structured to ensure the platform can never be sold or shut down by a corporate acquirer. All data stays on your own hardware by default, with no telemetry, no profiling, and no vendor with access to your home. Fully GDPR-compatible by architecture.
Trusted by more than one million households worldwide, and ranked the top open-source project by contributors in 2025.
Why choose Home Assistant over Amazon Alexa?
The decisive argument is data jurisdiction. Amazon Alexa is headquartered in US, which means personal data processed through it can be subject to non-EU legal regimes: the US CLOUD Act, FISA 702, or similar laws depending on the provider. After the 2020 Schrems II ruling, EU organisations must carry out a transfer impact assessment for every such data flow.
Home Assistant removes that overhead. As a Switzerland-based provider, it operates natively under GDPR, and data stays inside the EU/EEA by default. For regulated sectors such as health, public administration, and finance, that's not a nice-to-have but a requirement. For everyone else, it's concentration-risk insurance: you avoid depending on a single non-EU jurisdiction that can change the rules without warning.
