LeonR&Do IoT Lab: Total power consumption of a house (id-1) for 1 year period (second stage)

The data is stored in a series of objects, with each object representing a measurement of the power consumption at a specific time. The columns field is an array of strings that represent the names of the columns in the values array.

The values field is an array of arrays, with each inner array representing a single measurement of power consumption. The first element of each inner array is the timestamp, and the second element is the mean total power consumption of a 15-minute time interval. The power consumption is measured in watts.
