Historic Data

Historic Data (Data Collection)

Instructs the data logger to publish historic data records within a time range. This command only works with data tables that contain the MQTTPublishTable() CRBasic instruction. The data will be published in the same format as indicated in the table publish instruction. In the case of GeoJSON, the point coordinates used when re-publishing the data will be the latest values passed into the table publish instruction.
