What is Home Assistant

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.

:::caution You might run into CSRF errors, this is caused by a technology Home-assistant uses and not authentik, see this GitHub issue. ::: :::note For Home Assistant to work with authentik, a custom integration needs to be installed for Home Assistant. :::

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.

authentik configuration

Create a Proxy Provider under Applications > Providers using the following settings:
- Name: Home Assistant
- Authentication flow: default-authentication-flow
- Authorization flow: default-provider-authorization-explicit-consent
- External Host: Set this to the external URL you will be accessing Home Assistant from
- Internal Host: http://hass.company:8123
Create an Application under Applications > Applications using the following settings:
- Name: Home Assistant
- Slug: homeassistant
- Provider: Home Assistant (the provider you created in step 1)
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.

Home Assistant configuration

Configure trusted_proxies for the HTTP integration with the IP(s) of the Host(s) authentik is running on.
If you don't already have it set up, https://github.com/BeryJu/hass-auth-header, using the installation guide.
There are two ways to configure the custom component.
1. To match on the user's authentik username, use the following configuration:
```
auth_header:
    username_header: X-authentik-username
```
2. Alternatively, you can associate an existing Home Assistant username to an authentik username.
  1. Within authentik, navigate to Directory > Users.
  2. Select Edit for the user then add the following configuration to the Attributes section. Be sure to replace hassusername with the Home Assistant username. :::note This configuration will add an additional header for the authentik user which will contain the Home Assistant username and allow Home Assistant to authenticate based on that. :::
```
additionalHeaders:
    X-ak-hass-user: hassusername
```
  3. Then configure the Home Assistant custom component to use this header:
```
auth_header:
    username_header: X-ak-hass-user
```
