Reload all Home Assistant configuration

Use this action to reload all the YAML configuration that can be reloaded without restarting Home Assistant. A common use is to apply changes you made to your YAML files in one step, instead of reloading each part separately.

It calls the reload action on every domain that supports it. It also reloads the core configuration, themes, and custom Jinja templates. Before reloading, Home Assistant runs a basic configuration check. If that check fails, nothing is reloaded and the action raises an error.

Only users with administrator rights can run this action.

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 all configuration 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. Search for and select Reload all Home Assistant configuration.
6. Select Save.

Options in the UI

This action has no options.

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 homeassistant.reload_all. A basic example looks like this:

action: homeassistant.reload_all

Options in YAML

This action has no options.

Good to know

• This action includes the work done by the Reload Core configuration and Reload custom Jinja2 templates actions, plus a reload of themes.
• If the configuration check fails, nothing is reloaded. Fix the reported errors and try again.
