Refresh library

Use this action to tell Plex to scan one of its libraries for new and updated media. This is handy when you add files outside of Plex’s regular scan schedule and want them to show up right away.

Using this action from the user interface

If you prefer building automations and scripts visually, Home Assistant walks you through this action step by step. You pick what to target, tweak a few options, and save. No YAML knowledge required.

To refresh a Plex library from an automation or a script:

  1. Go to Settings > Automations & scenes.
  2. Open an existing automation or script, or select Create automation > Create new automation.
  3. If you’re setting up a new automation, add a trigger in the When section. Scripts don’t need a trigger. They run when something else calls them.
  4. In the Then do section, select Add action.
  5. From the search box, search for and select Plex: Refresh library.
  6. Enter the Library name you want to refresh.
  7. Optional: If you have more than one Plex server, enter the Server name to choose which one to use.
  8. Select Save.

This action does not support targets. In the UI, you are not prompted to choose an area, device, entity, or label.

Options in the UI

Library name

The name of the Plex library to refresh.

Server name (Optional)

The name of the Plex server to use. Only needed if you have more than one server configured.

Using this action in YAML

If you work directly in YAML, or you want to know exactly what Home Assistant does under the hood, this section has the technical reference. It lists the field names you use in YAML, their types, and which ones are required.

In YAML, refer to this action as plex.refresh_library. A basic example looks like this:

ActionActions are used in several places in Home Assistant. As part of a script or automation, actions define what is going to happen once a trigger is activated. In scripts, an action is called *sequence*. [Learn more]
action: plex.refresh_library
data:
  library_name: "TV Shows"

This scans the TV Shows library for new and updated media.

Options in YAML

library_name string Required

The name of the Plex library to refresh.

server_name string

The name of the Plex server to use. Only needed if you have more than one server configured.

Good to know

  • Plex scans your libraries on its own schedule. Use this action when you want a scan to happen right away, for example after a new download lands on your media drive.
  • The library name must match the name of a library on your Plex server exactly.

Tip

You don’t need to edit YAML to use these examples. Copy a YAML snippet from this page, open the automation editor in Home Assistant, and press Ctrl+V (or Cmd+V on Mac). Home Assistant automatically converts the pasted YAML into the visual editor format, whether it’s a full automation, a single trigger, a condition, or an action.
