Home Assistant

Open source home automation that puts local control and privacy first. Powered by a worldwide community of tinkerers and DIY enthusiasts

Installation

Enable Home Assistant by setting COMPOSE_PROFILES=homeassistant.

Set the HOMEASSISTANT_HOSTNAME, since it does not support running in a subfolder. Add the necessary DNS records in your domain.

You will need to allow Traefik to access Home Assistant by adding the following in homeassistant/configuration.yaml:

http:
  use_x_forwarded_for: true
  trusted_proxies:
    - 172.0.0.0/8 # You can put a more precise range instead

Set the HOMEASSISTANT_ACCESS_TOKEN for homepage support.

Backup

Enable Backups in HomeAssistant

We will create an automation that will create backups nightly and clear old ones.

Add a command_line inclusion in your configuration.yaml: command_line: !include command_lines.yaml

The command_lines.yaml defines a switch that removes backups older than 7 days:

- switch:
    name: Purge old backups
    unique_id: switch.purge_backups
    icon: mdi:trash-can
    command_on: 'cd /config/backups/ && find . -maxdepth 1 -type f -mtime +7 -print | xargs rm -f'

Then, create an automation that will trigger backups nightly and call the purge old backups switch:

alias: Backup Home Assistant every night at 3 AM
description: Backup Home Assistant every night at 3 AM
trigger:
  - platform: time
    at: "03:00:00"
action:
  - service: backup.create
    data: {}
  - service: switch.turn_on
    data: {}
    target:
      entity_id: switch.purge_old_backups
  - service: switch.turn_off
    data: {}
    target:
      entity_id: switch.purge_old_backups
mode: single

Save Backups Remotely

Home Assistant can be backed up in the cloud storage product of your choice with Rclone.

Before a backup can be made, rclone config must be run to generate the configuration file:

docker compose run --rm -it homeassistant-backup rclone config

It will generate a rclone.conf configuration file in ./homeassistant/rclone/rclone.conf.

Copy the backup environment file to backup.env and fill it as needed: cp backup.env.exmple backup.env

Variable Description Default
RCLONE_REMOTE_NAME Name of the remote you chose during rclone config
RCLONE_REMOTE_DIR Name of the rclone remote dir, eg: S3 bucket name, folder name, etc
CRON How often to run the backup @daily backup every day
TIMEZONE Timezone, used for cron times America/New_York
ZIP_PASSWORD Password to protect the backup archive with 123456
BACKUP_KEEP_DAYS How long to keep the backup in the destination 31 days

You can test your backup manually with:

docker compose run --rm -it homeassistant-backup backup
