Reload conversation agents

The Reload conversation agents action reloads the intent configuration of the default conversation agent and clears its cached intents.

This is useful while you are working on custom sentences or intents. After you change your configuration, reload the conversation agent to apply your changes without restarting Home Assistant.

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 reload conversation agents 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 Conversation: Reload conversation agents.
  6. Optionally, choose a Language to limit what gets reloaded.
  7. 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

Agent (Optional)

This action reloads the default conversation agent, regardless of which agent you select.
Language (Optional)

The language to clear cached intents for. When left empty, all languages are cleared.

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.
