Example add-on configuration:

databases:
  - homeassistant
logins:
  - username: homeassistant
    password: PASSWORD
  - username: read_only_user
    password: PASSWORD
rights:
  - username: homeassistant
    database: homeassistant
  - username: read_only_user
    database: homeassistant
    privileges:
      - SELECT

Option: databases (required)

Database name, e.g., homeassistant. Multiple are allowed.

Option: logins (required)

This section defines a create user definition in MariaDB. Create User documentation.

Option: logins.username (required)

Database user login, e.g., homeassistant. User Name documentation.

Option: logins.password (required)

Password for user login. This should be strong and unique.

Option: rights (required)

This section grant privileges to users in MariaDB. Grant documentation.

Option: rights.username (required)

Option: rights.database (required)

Option: rights.privileges (optional)

Restricting privileges of the user that Home Assistant uses is not recommended but if you want to allow other applications to view recorder data should create a user limited to read-only access on the database.

Home Assistant Configuration

MariaDB will be used by the recorder and history components within Home Assistant. For more information about setting this up, see the recorder integration documentation for Home Assistant.

Example Home Assistant configuration:

recorder:
