Then to get this data back for the graphs when requested...
SD card size is not the issue. I'm testing in my network with one sensor oversampling(1 min) temperature. In 4 months DB size is 5.5M. New version will also support averring of values. For example if I measure outside temperature with sampling rate 1 min, and then write in DB only one average value every hour or 30 min.
