If it recalculates the rain rate I suppose it should be OK.
There could theoretically be some minor inconsistencies between Meteohub and template data but no big deal.
But what about historical data import?
Meteohub can export to WSWIN and WD.
WD should be the way to go but you get only some sort of rain rate exported, so you definitely don’t get the right values for cumulative rain and rain rate - at least the last time I’ve tried it was the case.
