This function is called when a Service 3 Housekeeping packet is received.

enumerations does not work in Python. For example use:

if object_id.value == ObjectIds.TEST_OBJECT.value

The first list contains the header columns, the second list the list with

|
at the end of the housekeeping packet. The last value is the number of parameters.
