That is correct. The metric being returned is not E001_C04_kW; it is a
calculated value. In this case it is derived from a single metric E001_C04_kW,
but in general could be derived from multiple metrics.
You'll see the same in the PromQL browser. For example, if you give this
query:
up
then each metric returned is of the form up{...labels...}. But if you give
this query:
up * 2
then each metric returned is of the form {...labels...} (i.e. there is no
metric name, because this is no longer the "up" metric but a calculated
value).
