Weather data history questions

I went back to look at about a year ago to see what the brightest days were in comparison to today, for example, and it looks like data is cut off at 365-days. Is a greater history something that could be made available? Also, is there an option I haven’t seen for a historical card of some sort to give the historical highs/lows for the various datasets available to us?

my brightness data is available from 2018. did you perhaps did a factory reset at some point and create a new station on 4 jun 2020?
