Looks like this component is not working with Python 3.7.0? I see 3.7 is final version now so I updated Hassbian Python version and this was the only component I have that stopped working.
File “/srv/homeassistant/lib/python3.7/site-packages/homeassistant/setup.py”, line 146, in _async_setup_component
component.setup, hass, processed_config) # type: ignore
AttributeError: module ‘custom_components.climate’ has no attribute ‘setup’
