Bug in config_flow: Regression from Commit 02c1ae1

[Lawrence Akka]

I have been unable to configure the integration for some time. It generates a traceback like this:

Traceback (most recent call last):

TypeError: object EntityRegistry can't be used in 'await' expression`

As indicated, the problem is indeed at line 159 of config_flow.py:

https://github.com/MindrustUK/Heatmiser-for-home-assistant/blob/1724d8318b6cd2a6a6ac299ceedf3eaccdd94db7/custom_components/heatmiserneo/config_flow.py#LL159C9-L159C53

the async_get function in entity_registry.py:

https://github.com/home-assistant/core/blob/71e8ee52e5484b2d17c0a2a9aed264c924f5b4fc/homeassistant/helpers/entity_registry.py#L473

is not an awaitable! Changing line 159 to entity_registry = async_get(self.hass) fixes the issue.

I would submit a PR, but I havent got a dev environment set up on this machine ...

Thanks for reporting and troubleshooting! I've merged in a fix for this.
