IntesisHome integration ¿broken as of dec. 2020?

First of all, I want to say thank you to all the folks that actively answer and help on this community. I have learned a lot and solved many issues by reading existing posts. I am new to HA, (less than 2 months) but achieved many of my goals with HA.
Now it happens to be different, since I am not able to make IntesisHome integration work.
I am on 2020.12.1 version, Host is Home Assistant OS 5.9.

I added in configuration.yaml this entry, using my real username and pass (which work perfectly in Intesis mobile app:

climate:
  - platform: intesishome
    username: YOUR_USERNAME
    password: YOUR_PASSWORD

The error I get is:

Traceback (most recent call last):
  File "/usr/src/homeassistant/homeassistant/helpers/entity_platform.py", line 199, in _async_setup_platform
    await asyncio.shield(task)

    return list(config_fan_map.values())
AttributeError: 'int' object has no attribute 'values'

My AC is a Fujitsu ACY 100K-KA, with 5 modes enabled (cool, heat, dry, auto, fan only) and 6 fan speeds plus auto fan.
Is there something I miss or, indeed, there is a real issue with this integration?
Cheers,
