Hass.io Architecture

Architecture Overview of Home Assistant

Host Control (HC)

This is a daemon running on the host machine that allows the supervisor to control certain aspects of the host OS:

  • Power cycle (restart, turn off)
  • Manage network settings
  • Local updates


Our pre-build images are based on HassOS which is based on BuildRoot. Any Linux machine can be turned into a Hass.io host by running the installer.


The supervisor offers an API to manage the host and running the Docker containers.

Configuration panel

The configuration panel lives inside the supervisor but is accessible via the Home Assistant user interface. The configuration panel allows the user to manage the installation.
