Ties speakers, cameras, thermostats and thousands of third-party devices into one app with voice control, and that breadth of device support is the hardest part to replace. The app is free, while Google Home Premium costs 10 dollars a month or 100 a year, doubling to 20 for the Gemini video tier. Alphabet runs it from the United States.

About Home Assistant
Home Assistant is the world's most popular open-source home automation platform, letting you control, automate, and monitor all your smart home devices through a single local interface, without cloud connectivity or subscriptions. 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. A fully customisable dashboard shows exactly what you want, whether that's room-by-room energy use, security camera feeds, or weather data. The built-in Assist voice engine processes commands locally without routing speech to external servers.
Key benefits:
- 3,500+ integrations covering virtually every smart home ecosystem and device brand
- 100% local processing with no cloud dependency and no subscription required for core use
- Visual automation editor with triggers, conditions, and multi-step action sequences
- Customisable dashboards with drag-and-drop cards for any device or sensor
- Local voice assistant (Assist) with no speech data sent to external servers
- Matter and Thread support for the latest smart home interoperability standards
- Open-source (Apache 2.0) to self-host on a Raspberry Pi, VM, or dedicated hardware
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 Google Home?
The decisive argument is data jurisdiction. Google Home is headquartered in the United States, 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 under Swiss FADP + GDPR for EU users, and data stays in Switzerland, which the European Commission recognises as offering an adequate level of protection. 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 jurisdiction that can change the rules without warning.
