The local/GDPR choice for controlling your home without the cloud.
Security reflects where data goes, requested permissions and incidents on record at the verification date. It is not a guarantee of zero risk: check the deployment mode and the connections you enable.
What it does, concretely
Managing connected devices from different brands often means juggling multiple apps and entrusting your data to remote servers. Home Assistant centralises the control of all your smart home equipment in a single interface, without relying on the cloud.
The software is installed on your own hardware, for example a Raspberry Pi or a local server, and communicates directly with your devices on your network. It offers customisable dashboards, an advanced automation engine, and the Assist voice assistant, which processes voice commands locally without sending them to a third-party service.
Home Assistant is aimed at people who want to control their smart home while keeping full ownership of their data. It is particularly suited to users comfortable with self-hosting and technical configuration, even though most settings can be handled through the graphical interface without writing any code.
It is less suited to people looking for a plug-and-play solution with no initial setup: installation and onboarding require a time investment, especially when connecting and organising devices.
