National Weather Service forecast sensor for Home Assistant

sensor_forecast_nws.configuration.yaml

# Rather than create a whole new hass component, this minimal `rest` sensor configuration is sufficient for a
# high-quality National Weather Service point forecast. 
# See https://forecast-v3.weather.gov/documentation for details on this point-based GeoJSON forecast and more.
# Thanks to the National Weather Service for their efforts providing timely weather data to protect life and property.
