icon property
optional A machine-readable text summary of this data point, suitable
for selecting an icon for display. If defined, this property will have one
of the following values:
clear-day, clear-night, rain, snow, sleet, wind, fog, cloudy,
partly-cloudy-day, or partly-cloudy-night.
Developers should ensure that a sensible default is defined, as additional values, such as hail, thunderstorm, or tornado, may be defined in the future.
Implementation
