Introduction

The EMS has access to worldwide weather data that you can use in your account. You can access hourly weather data for different weather variables such as local Temperature, Humidity, Solar Radiation...

Available parameters

The available parameters can vary from one weather station to another. Generally the available parameters are:

  • Accumulated liquid equivalent precipitation - 315
  • Accumulated snowfall - 323
  • Air pressure - 318
  • Cloud coverage - 320
  • Dew point - 312
  • Diffuse horizontal solar irradiance - 331
  • Direct normal solar irradiance - 332
  • Solar radiation intensity (W/m2) - 316
  • Solar radiation energy (Wh/m2) - 338
  • Global horizontal solar irradiance - 333
  • Heat index - 310
  • Relative humidity - 302
  • Sea level pressure - 319
  • Solar azimuth angle - 336
  • Solar elevation angle - 335
  • Solar hour angle - 337
  • Temperature - 301
  • UV Index - 334
  • Wind direction - 314
  • Wind speed - 313

Create a new Virtual Weather Gateway

  1. In the upper right corner of your main page select "Settings":

  3. Select "Register a new gateway":

  4. Select "Virtual Weather Station" and click to "Next":

  5. Configure your Internet Weather Station device. You will have to select the city and the postcode (optional in cases where postcode doesn't exist), and in "Weather station" all the weather stations available will appear. A map will show the exact location of the weather station once selected.

    Notice that for each weather station a list of the available parameters will be shown under the map.

    Important : This Virtual Weather Gateway allows you to import the historical data for a year (up to the moment when you create it) for all the parameters. To do so, check the "historical data" box.
    This can take a few minutes to import.

Once you create the weather station, a new gateway will appear in your list of gateways. A new meteo device will appear in the list of devices for that gateway that you will have to accept.

Once it is accepted, data will be received by that meteo device, and a list with all the parameters available will appear in the device, so you can choose which parameters to accept and use in your account.

Remember to link the device to a location in order to use it in your analyses, dashboards, reports and alerts.

 

Migration of an historic weatherstation from Wunderground

In case you were using the Internet Virtual Gateway Wunderground (which provided service until early 2019), you can just create the Virtual Weather Station as explained earlier on this article and set the meteo device from Wunderground as historical device of the new one, by joining devices.

The EM Platform can gather weather information from the Internet. This system provides temperature and humidity readings worldwide and has a 5% error margin.
