Home Assistant

  • Add-ons run only on Home Assistant Operating System installations, and Container installations have no access to them
  • Thread and Z-Wave are controlled by add-ons, so a Container install has no out-of-the-box support for either
  • A Container installation means bringing your own Linux host with Docker and handling updates by hand
  • The recommended install path expects dedicated hardware such as a Raspberry Pi 4 or 5 with at least 2 GB of RAM, an Odroid, or an x86-64 machine
  • Every documented hardware option requires a wired Ethernet connection
