Folder sensor

Sensor for monitoring the contents of a folder. Note that folder paths must be added to whitelist_external_dirs. Optionally a wildcard filter can be applied to the files considered within the folder. The state of the sensor is the size in MB of files within the folder that meet the filter criteria. The number of filtered files in the folder and total size in bytes of those files are exposed as attributes.


To enable the folder sensor in your installation, add the following to your configuration.yaml file:

  - platform: folder
    folder: /config
