- What it is
- The official Home Assistant documentation for connecting Home Assistant to Google Assistant. It describes the automatic setup through Home Assistant Cloud and the manual setup, which needs an externally reachable instance with a hostname and SSL certificate.
- How much weight it carries
- Published and maintained by the Home Assistant project, for its own integration. It describes the integration's setup and requirements, not Google's own roadmap, so Google's product changes are sourced separately.
