Is there any way of retrieving historic data for, say, the last 6 months - namely grid voltage and grid frequency....is it stored anywhere?

It exists in the Fox Cloud, data is only updated every 5 minutes.
Filter choices are 'RVolt' & 'RFreq' the R is for 1 of the 3 phases (R, S & T)
AFAIK, you can only download data for the day for the website, if you are more technically inclined, there might be a way via API calls (that way I don't know)
