  1. ‘uptime’ is the total time that the system was active and recording. The ‘total duration’ is ‘date of last measurement’ minus ‘date of first measurement’. The correlation of the mains meter with the sum of all submeters gives an indication of how much of the variance in the mains signal is captured by the submeters. The proportion of energy submetered is the total energy captured by the submeters divided by the total energy captured by the mains meter. The dropout rate (ignoring large gaps) gives a measure of the rate at which packets were lost due to radio errors (large gaps are ignored because these are often caused by a meter being deliberately unplugged). Some metadata is not available because the occupants are no longer contactable.
