mudpi_openWeatherAPI

Functionality

Get Forecast weather

• Rain (sum, min, max, avearge) over x hours
• Temp (min, max, average) over next x hours
• Chance of precipitation over the next x hours

Get Historical Data (did it rain in the last hour) or Rainfall in the 24hours

• Rain in the last hour (x hours)
• Total Rain fall in the last x hours
• Min Max temp over the last 24 hours

Get Current weather

• Is it currently rainning (custom measurement)
• Current List of any open weather api measurement (temp, humiditiy, sunset time, sunrise time)

Other

• imperial vs metric For temperature in Fahrenheit and wind speed in miles/hour, use units=imperial For temperature in Celsius and wind speed in meter/sec, use units=metric Temperature in Kelvin and wind speed in meter/sec is used by default, so there is no need to use the units parameter in the API call if you want this

Weather Types and Measurments

Current will return the current measurements, updated intra hour by open weather map. See documenation below.

Forecast and Historical take a look back window (in hours) and aggregate the hourly measurement information. You can return a Sum, Min, Max, and avearge for any of the listed measurements below. Historical/Forecast allows for up to 24 hours. (e.g. "mintemp", "maxpop", "avgrain")

Current	Forecast	Historical
	sum / min / max / avg	sum / min / max / avg
temp	temp	temp
feels_like	feels_like	feels_like
pressure	pressure	pressure
humidity	humidity	humidity
dew_point	dew_point	dew_point
clouds	clouds	clouds
visibility	visibility	visibility
wind_speed	wind_speed	wind_speed
wind_deg	wind_deg	wind_deg
rain	rain	rain
uvi	uvi
sunrise
sunset
israinning (custom measurement)
	pop (Probability of precipitation)
	wind_gust
