License
Apache-2.0
Hosting Model
Self-host (your server)
Platforms
mobilewebself-hostedself-host, real ops
Installation
Flash the Home Assistant OS image to supported hardware or a VM; Container and Core installs are also documented
Operational Setup
The first real cost is an always-on supported machine and time spent pairing devices; safe remote access, backups, radio dongles, and vendor-specific integration failures become the owner's responsibility.
Where Your Data Lives
Configuration, automations, integrations, dashboards, and secrets live under the local `/config` directory; history defaults to the local SQLite `home-assistant_v2.db` database and can be moved to MariaDB, MySQL, or PostgreSQL. Device traffic and state remain on the Home Assistant host unless a configured integration sends them elsewhere.
The Catch / Trade-off
Home Assistant is better for devices in the house, but its SaaS and social-app breadth is narrower and it requires an always-on controller plus ongoing integration maintenance.
