Logical IDs (LIDs)

 

The table below contains a comprehensive list of the Logical IDs (LIDs) available for reading in the DI SDK and through the metering API. It also provides information on whether each LID should be retrieved via the subscription or the get-once methods, and, once retrieved, what type should be used to read the value out of the ApiVariableType correctly.
