Web API for Data Retrieval

The measurement data can be access through a web-interface:

http://www.[YOUR URL.COM]/export.export.php?node_id=[YOUR NODE ID]&token=[YOUR TOKEN]&campaign_name=[YOUR CAMPAIGN NAME]&campaign_description=[YOUR CAMPAIGN DESCRIPTION]&date_start=[YOUR START DATE]&date_end=[YOUR END DATE]

[YOUR NODE ID] is a single node ID (e.g. '801') or a comma-separated list of node IDs (e.g. '801,802,805'). If a campaign name ([YOUR CAMPAIGN NAME]) is provided, [YOUR NODE ID] can be set to 'all'. In that case, all node IDs registered to a campaign name will be retrieved. The output data is json-formatted.

Example:

Node ID: 801
Sensor Description: SHT31
Measured Entities: Air Temperature (indoor), Relative Humidity (indoor)
Measurement Units: °C, %
Sensor Module Type: 2
Number of Values: 2

Measurement Timestamps: 1583780593, 1583780294, 1583779393 (UNIX Timestamps)
Measured Temperatures: 21.7609, 21.8757, :21.7742
Measured Humidities: 51.0765, 50.7057, 48.9708
