Import Error on upgrade to Python3.8

[tinstep]

Hi
After upgrade to 0.102.0 Home Assistant and python upgrade to 3.8 (from 3.6), I got the following error in the logs and the climate_ip component is unavailable.
It cant import 'ATTR_HVAC_ACTIONS'

Hi
After upgrade to 0.102.0 , Same problem here

[GGalloppa]

Same here

arch	x86_64
dev	false
docker	true
hassio	true
os_name	Linux
python_version	3.7.4
timezone	Europe/Rome
version	0.102.0
virtualenv	false

I'm using Climate_ip platform from HACS to connect to a Samsung CDZ
https://github.com/SebuZet/samsungrac/

I've checked and think to have found the issue:
homeassistant.components.climate const after update is ATTR_HVAC_ACTION
while climate_ip is calling ATTR_HVAC_ACTIONS

a wired thing is that the same const file include both
ATTR_HVAC_MODE and
ATTR_HVAC_MODES

don't know if this is wanted or just miss the ATTR_HVAC_ACTIONS in the new HA climate file

[atxbyea]

Broken here after 0.102.0 also, tried removing "ATTR_HVAC_ACTIONS" and "MODES" but that only made it worse ;-)

[emme73]

I think we do need to replace all calls to ATTR_HVAC_ACTIONS to ATTR_HVAC_ACTION in the samsungrac component

unfortunately my HA hangs and I'm not at home to reboot it :(

[emme73]

folks, I confirm! you need to edit climate.py file under /config/custom_components/climate_ip and replace the 2 references on ATTR_HVAC_ACTIONS to ATTR_HVAC_ACTION, save and reboot, it will work

@emme73 That worked like a charm.
well done and thanks!

Verified, working nice here too, I will create a pull request for it.
