Create a new Altair IoT connection in the Manage connections box. The access key, secret key and the region are required.
Use category
Whether to query a whole Altair IoT category instead of a list of thing UUIDs.
Thing ids
Only available when the use category flag is not set. List of Altair IoT Things UUIDs to be queried.
Category
Only available when the use category flag is set. Altair IoT Things category to be queried.
Start time
Optional filter for the attribute changes query. The format is "yyyy-MM-dd HH:mm:ss". If it is empty, the whole history is queried. If it is set, the query filters attribute changes starting at this date.
End time
