 The `file` platform allows you to store notifications from Home Assistant as a file.
 
 To enable file notifications in your installation, add the following to your `configuration.yaml` file:

+The `file` sensor platform reads the entries from a plain-text file and shows the found value. Only the last line of the file is used. This is similar to do `$ tail -n 1 sensor.txt` on the command-line. Note that file paths must be added to [whitelist_external_dirs](/docs/configuration/basic/).
