The downloader component provides a service to download files. It will raise an error and not continue to set itself up when the download directory does not exist. The directory needs to be writable for the user that is running Home Assistant.

To enable it, add the following lines to your configuration.yaml file:

# Example configuration.yaml entry
  download_dir: downloads

Configuration variables:

  • download_dir (Required): If the path is not absolute, it’s assumed to be relative to the Home Assistant configuration directory (eg. .homeassistant/downloads).
