The payload from this command - \x00\x05\x00\x00\x06\x02 - appears to be correct based on the z-wave spec:
If this field advertises a non-existing parameter, a receiving node MUST advertise zero values in the Format and Size fields. The Next Parameter Number field MUST advertise the next available configuration parameter.
The spec also includes 0 in the table of values allowed for size in this particular report:
@nayelyz Could the handling of this payload be improved to return the data it contains - the parameter number (5), size (0), next valid parameter number (6), and no bulk support - instead of throwing an error?
