The Weather Underground widget allows new stations to be added to the database, as well as activate/deactivate stations already in the database. These are stored in DT_LOGGER, DT_LOGGER_SERIES. An API (Application Programming Interface) key is needed to add stations. One can be obtained with a paid subscription at http://www.wunderground.com/weather/api/. Once obtained, enter the API key through the Widget Editor.
The top section of the Weather Underground widget is used for adding new stations. If a station is entered that has already been added, the data will be updated. The lower section contains a tree of all stations currently in the database. Browse through the tree to see which stations are active or inactive. Beneath each station logger node are related series nodes. These are the data fields that will be available after data are collected using the Weather Underground Agent.
Add Station
To add a station, enter the Station ID into the Station ID box at the top of the widget and click Add. If the add is successful, the box will be cleared. The tree below will also reload to show the new station. Examples of what can be entered as a station ID are shown below (and also available as a tooltip by hovering over the Station ID box). There is support for:
•US state/city
•US zip code
•Country/city
•Latitude, longitude (format: latitude/longitude with no space)
•Airport code
•Private weather station ID
•Autoip
•Autoip to a specific IP address
The station names are a combination of the public name (e.g., CA/San_Francisco), which should match what was entered in the station ID box, and the private station name (e.g., KCASANFR58), separated by a '#'.
Activate / Deactivate Stations
A station that shows the green icon 
is currently registered and active in EQuIS Live, and data are being automatically loaded into EQuIS Live. Right-click an active station logger node and select Deactivate to stop loading data from that station. Existing data will remain in the EQuIS Live database, but no new data will be loaded until the station is activated again.
A station that shows the red add icon 
is not currently active. This can be because the station has never been added to the EQuIS Live system or the station was added previously, but is currently inactive (no data are being loaded). Right-click the station logger node and select Activate to activate the station and begin loading data.
