External data sources

External tags hold information from external data sources, such as weather services, electricity stock markets, or other API interfaces.

Create external data source

In tree, a new external tag can be created in the External data sources node via the icon.

Configuration of an external data source with selection of weather forecast

In addition to custom data sources, several data sources predefined by AnyViz are available:

Current weather	By specifying the location and unit system, the current weather at the desired location can be determined.
Weather forecast	By specifying the location and unit system, the daily and hourly weather forecast is retrieved.
Air pollution	Current air pollution data for a specified location.
Electricity spot prices	Wholesale electricity market prices (see details).

Custom data sources

Data from other systems can be retrieved via cyclic GET or POST requests if the data is available in JSON format. When Custom is selected, the following options appear:

Configuration of a custom external data source with selected GET method and input of the URL, as well as the query interval.

Method	In most cases, data is retrieved via GET. If a request body is needed, POST must be selected.
URL	The request URL to fetch the data
Request Body	Only for POST: The JSON payload to be transmitted in the request.
Interval	Query interval in minutes
Custom headers	If the destination requires additional request headers (e.g. for authentication), these can be specified in the form of a key/value list.

Caution: The URL of custom data sources must be whitelisted first. Please contact AnyViz support for this.
