  1. The metadata attributes are accessible via a HDF5-attribute-path. All physical values are provided in base units (Volt, Ampere, Hertz), and the timestamp information refers to the first sample in the respective data file. The < dataset > placeholder can be either voltage, current1 for the coffeemaker’s current from socket 1, or current6 for the socket 6 background-noise current.
