Description

What were you trying, what has happened, what went wrong, and what did you expect?

Code and Logs

# code and logs here.

# please use the following to format logs when posting them here
import logging
import pymodbus
pymodbus.pymodbus_apply_logging_config(logging.DEBUG)

Once mypy is properly implemented (thanks to @alexrudd2), we should get to a level similar to:
https://github.com/home-assistant/core/blob/dev/mypy.ini

Then I suggest (but you decide):

• activate the options that are (relative) easy to solve
• keep the rest deactivated
• Group the ones you think we should activate for in a interface module
• Group the rest as unwanted
  I have done a similar thing in the pylint setup, and it helps me remember that an option was tried and discarded etc.

You do not need to do it all in this PR, just put it up for review when you want.

I think we can safely close this now.
