Commentary on the data fields above, they have been grouped based on sample analysis but this could be wrong. If you see a new pattern not noticed before you may be correct.
*Field 10 - Value in seconds since meter powered on, '''easy way to see last time the meter experienced a power outage.'''
'''*Field 15 - This value counts from near 0 to around 3FFF and rolls over, not sure what it is. Have not been able to correlate the counting value or speed vs time to any sort of power utilization.* NEW **'''
'''Field 15''' - Timing in hundredths of a second, counts from 0 to 167.99 (0x419F) seconds then rolls over to 0 again. Credit for this discovery goes to an anonymous reader who examined the dataset at the bottom of the page!!
