I ran into the same problems. I’ve switched to https://github.com/GuGu927/hass-smartthinq
The manifest should automatically install the proper wideq version. You will have to put in a bit of work to translate the Korean characters in both the custom component and wideq, but it worked fine for me after with a lg washer.
Also add this to init.py in the wideq folder to avoid ssl errors:
requests.packages.urllib3.disable_warnings()
requests.packages.urllib3.util.ssl_.DEFAULT_CIPHERS += 'HIGH:!DH:!aNULL'
try:
requests.packages.urllib3.contrib.pyopenssl.DEFAULT_SSL_CIPHER_LIST += 'HIGH:!DH:!aNULL'
except AttributeError:
# no pyopenssl support used / needed / available
pass
