Installing an extension from HACS

  1. Install HACS itself once, following the guide on hacs.xyz – it needs a GitHub account and runs as an integration of its own.
  2. "Open in HACS" takes you to the extension in your own Home Assistant. Download it there.
  3. Restart Home Assistant after downloading an integration, then add it under Settings → Devices & services. A dashboard card or theme only needs the browser to reload.

Extensions in HACS are not reviewed by the Home Assistant team, and each runs with the rights of Home Assistant. Prefer extensions that are kept up to date, and read what an integration asks for. One with the domain of an official integration takes that integration's place once installed.

Source: the published data of HACS – name, kind, author, stars, downloads (counted for releases only), version and date. Extensions HACS removed or marked as dangerous are left out. The descriptions are written for this page from the author's own one-liner; where none is written yet, that one-liner is shown.
