To enable it, add the following lines to your
# Example configuration.yaml entry downloader: download_dir: downloads
Go to the “Developer Tools”, then to “Call Service”, and choose
downloader/download_file from the list of available services. Fill the “Service Data” field as shown in the example below and hit “CALL SERVICE”.
This will download the file from the given URL.

When a download finished successfully, Home Assistant will emit a ‘downloader_download_completed’ event to the event bus which you can use to write automations against. In case download failed another event ‘downloader_download_failed’ is emitted to indicate that the download did not complete successfully.
Along with the event the following payload parameters are available:
- alias: "Download Failed Notification" trigger: platform: event event_type: downloader_download_failed action: service: persistent_notification.create data: message: " download failed" title: "Download Failed"
