core: Cannot configure Wemo Dimmer as homekit controller device

Home Assistant release with the issue:

0.87.1

Last working Home Assistant release (if known): N/A

Operating environment (Hass.io/Docker/Windows/etc.):

Linux (arch)

Component/platform:

https://www.home-assistant.io/components/homekit_controller/

Description of problem: I am unable to configure any of my Wemo dimmers using homekit controller.

Problem-relevant configuration.yaml entries and (fill out even if it seems unimportant): The only configuration changes are:

# Discover some devices automatically
discovery:
  enable:
    - homekit

logger:
  default: debug

Traceback (if applicable):

Additional information:

They are all on the latest firmware,11215 (and use to work fine as wemo entities before the firmware upgrades).

There seems to be an anomaly as soon as they get discovered (see the last line of the follow snippet):

When I click the “configure” button in the web interface, (1 device at a time (making sure I have the right HomeKit code and device pair) I see the following again in the log:

2019-02-12 02:43:28 DEBUG (MainThread) [homeassistant.components.websocket_api.http.connection.140059089157648] Received {'type': 'config/entity_registry/get', 'entity_id': 'configurator.wemo_dimmer', 'id': 17}

Then if I try to put in the HomeKit code and click submit, sometimes it looks like it’s going through fine, but nothing happens, the configurator is still displayed and no new entity is created:

If I try hitting submit (HomeKit code) again, I see:

And there is definitely no network configuration issue.

If I go in Developer tools -> Services -> homeassistant.update_entity on configurator.wemo_dimmer, I see this in the log:

2019-02-12 04:06:30 DEBUG (MainThread) [homeassistant.core] Bus:Handling <Event call_service[L]: domain=homeassistant, service=update_entity, service_data=entity_id=configurator.wemo_dimmer>
2019-02-12 04:06:30 WARNING (MainThread) [homeassistant.helpers.entity_component] Forced update failed. Component for configurator.wemo_dimmer not loaded.

The Configurator widget stays displayed in the Notifications panel (even after a restart of home assistant).

This was noticed after a (countless) fresh install of home assistant and a fresh complete reset the Wemo dimmers. I also tried re-install the Wemo app on my iPhone.

During this whole process I also noticed I can’t discover the Wemos as Wemos anymore, but only homekit devices, not sure if that is normal.

EDIT: formatting EDIT2: I forgot to mention I am able to use all these devices successfully in the Wemo app, add them to the Home iOS app through the Wemo app and use the Home iOS app flawlessly.
