Thanks for the PR.

So importing directly from homeassistant.core_config isn't the correct way? I can only find references to core_config. Where did you get the reference to helpers.typing from?

So importing directly from homeassistant.core_config isn't the correct way?

According to the HA dev draft blog post it is not the correct way if it is only used for async_setup.

Normally, integrations won't need to use the core Config class. But there's been custom integrations that have incorrect type annotations where the config object passed to the integration's async_setup is specified as a Config instance:

A correct type annotation would be like this:

from homeassistant.helpers.typing import ConfigType

async def async_setup(hass: HomeAssistant, config: ConfigType) -> bool:
    """Set up the integration."""

Ah, I missed this one. Thanks for the explanation!
