You can use this add-on to check whether your configuration files are valid against the new version of Home Assistant before you actually update your Home Assistant installation. This add-on will help you avoid errors due to breaking changes, resulting in a smooth update.
### How to use this add-on
1. Just start the add-on.
2. Wait (On a Raspberry Pi it can take several minutes).
3. If you see the following output then you are good to go to update Home Assistant: `[Info] Configuration check finished - no error found! :)`.
If you get errors, then you should look for **Breaking Changes** against the version you specified for this add-on and change your configuration accordingly.
### Add-on configuration
```json
{
"version": "latest"
}
```
{% configuration %}
version:
description: Version of Home Assistant that you plan to install.
required: true
type: string
{% endconfiguration %}
