Conflicting setup requirement with standard library for Python 3.7 / 3.8

[MartinHjelmare]

• This library supports an integration in Home Assistant.
• One or more of the requirements of this library (see below) conflicts with one or more standard library modules for Python 3.7 and/or 3.8.
• To avoid issues it would be good if this library would remove these conflicting requirements from your library setup requirements or use a condition to only install the requirements when using a lower Python version.
• If a setup.py file is used it means updating the install_requires list and removing or updating the conflicting requirements.
  • See this blog for how to use a condition in install_requires: https://hynek.me/articles/conditional-python-dependencies/
• Found conflicts:
  • asyncio

Thanks for your support of Home Assistant!
