Weather Data Interface (WDI) API

An Itron-developed API that provides weather data to various Itron applications. Itron applications that use weather data may only utilize some of the data types, such as temperature or humidity. Weather data is provided in CSV (comma-separated values) file format, which is described in this guide. Daily weather files are the preferred frequency of delivery because they provide coverage if there is a problem with the weather feed from Itron's weather provider. Historic hourly weather data is available for North American sites and most international sites. Basic data includes temperature, dew point, and barometric pressure and is generally updated hourly. Optional weather data is available for some locations and includes wind speed and direction, gusts, sky, ceiling, visibility, heat index, wind chill, snow depth, 6-hour and 24-hour maximum and minimum temperatures, and 3-hour, 6-hour, and 24-hour precipitation amounts. For many stations. forecast data is also available, including daily maximum and minimum temperatures for the next two days.
