Home-Assistant

What is Home-Assistant​

From https://www.home-assistant.io/

note

Open source home automation that puts local control and privacy first. Powered by a worldwide community of tinkerers and DIY enthusiasts. Perfect to run on a Raspberry Pi or a local server.

warning

You might run into CSRF errors, this is caused by a technology Home-assistant uses and not authentik, see this GitHub issue.

Preparation​

The following placeholders will be used:

  • hass.company is the FQDN of the Home-Assistant install.
  • authentik.company is the FQDN of the authentik install.

Home-Assistant​

This guide requires https://github.com/BeryJu/hass-auth-header, which can be installed as described in the Readme.

Afterwards, make sure the trusted_proxies setting contains the IP(s) of the Host(s) authentik is running on.

Use this configuration to match on the user's authentik username.

auth_header:
    username_header: X-authentik-username

If this is not the case, you can simply add an additional header for your user, which contains the Home-Assistant Name and authenticate based on that.

For example add this to your user's properties and set the Header to X-ak-hass-user.

additionalHeaders:
    X-ak-hass-user: some other name

authentik​

Create a Proxy Provider with the following values

  • Internal host

    If Home-Assistant is running in docker, and you're deploying the authentik proxy on the same host, set the value to http://homeassistant:8123, where Home-Assistant is the name of your container.

    If Home-Assistant is running on a different server than where you are deploying the authentik proxy, set the value to http://hass.company:8123.

  • External host

    Set this to the external URL you will be accessing Home-Assistant from.

Create an application in authentik and select the provider you've created above.

Deployment​

Create an outpost deployment for the provider you've created above, as described here. Deploy this Outpost either on the same host or a different host that can access Home-Assistant.

The outpost will connect to authentik and configure itself.
