Ansible Collection - jhampson_dbre.home_assistant

A collection of roles for installing and configuring Home Assistant Supervised on Debian 11.

To see a real-world example of using this collection, check out the repo I use for my Home Assistant setup on GitHub.

WARNING: The roles in this collection can make changes to Home Assisant's configuration.yaml and restart Home Assistant. As recommended before making any changes to Home Assisant, ensure you have a good snapshot of your current configuration.

Roles

Minimal installation

These roles attempt to implement the strict set of requirements for installing Home Assistant Supervised available here. While every effort has been made to ensure these roles complies with ADR-0014, no guarantee can be made it does now, or in the future. These roles may have software package requirements (e.g. python3-apt) that are not specified by ADR-0014. To date these have not caused Home Assistant to report an unsupported installation, but please file a GitHub issue if you encounter any problems.

  1. preinstall_config - Prerequisite configuration for Home Assistant Supervised installation

  2. supervised_install - Supported installation of Home Assistant Supervised on Debian 11

Additional roles

These roles provide additional functionality to secure and enhance the minimal install of Home Assistant Supervised. These are roles I use myself and do not strictly comply with ADR-0014. However ADR-0014 states that maintaining and securiting the operating system is the responsibility of the user, and these roles fulfill that requirement without interfering with the Supervised installation.

  1. harden_os - Enable automated Debian security updates and restrict SSH access
  2. fail2ban - Install fail2ban, configure it to blacklist IPs with excessive failed login attempts to Home Assistant, and add the fail2ban integration to Home Assistant
  3. install_hacs - Install the Home Assistant Comunity Store, a marketplace of community-contributed custom components for Home Assistant
  4. os_agent_auto_update - Configures automatic updates to OS Agent component using ansible-playbook scheduled with cron

Example Playbook

---
# Minimal Install
#
# Initial setup connects as root over SSH to create
# a new, non-root account to use going forward.
# After the first run, `ansible_user: root` can be removed
# and the non-root account can be used (e.g. as host_var)
- name: Initial OS setup
  hosts: all
  vars:
    ansible_user: root

      import_role:
        name: jhampson_dbre.home_assistant.preinstall_config
      vars:
        has_reserved_ip: true

# Since preinstall_config creates a non-root account with sudo access,
# we can use `become: yes` for privilege escalation
# instead of logging in directly as root.
#
# Use `force_handlers: true` to ensure to ensure any changed services
# are restarted even if an error is encountered before the play ends
