Thanks for your contribution!
I have some minor issues that I would like to address before merging it.

+	fs.Float64("symo.offset-consumed", config.Symo.OffsetConsumed, "Offset for consumed")
+	fs.Float64("symo.offset-produced", config.Symo.OffsetProduced, "Offset for produced")


Please describe the flags better. What does "offset for consumed/produced" mean? What unit (if there is)?
If the values are only relevant for the smart meter endpoint, maybe make it symo.smartmeter.offset-{consumed/produced}?

The offset is meant to make it possible to keep the metric in sync with the official electric meter. The unit is Wh.

Ok, thanks. I'd propose to update the desc accordingly (better description welcome).

I don't know the smart meter data...
Is this offset actually required or important here? What is the semantic of the offset? Or is this more relevant to your personal use case?

Why expose this type? It's not meant to be public (i.e. usable by other Go packages), but is merely a struct to parse the JSON

From this naming alone it's not clear to me what it means or when it's relevant. Please either try to find a better name, or add field comments describing its effects.
