Method showing how you can create a lightflow for the Yeelight smart lights using Python

setupWeatherFlowYeelight.py

def setupWeatherFlow(bulb,weather,durationFlowSeconds=60):
    """
    We use HSV color transitions. In case there is no precipitation, the color will remain static for a minute or two.
    If there is precipitation, the light will pulse with varying levels of brightness.
    Depending on the temperature the light will be deep red if it is hot or deep blue if it is freezing.
    The flow itself will end automatically based on the durationFlowSeconds parameter.
