So… I know there are plenty of topics on this, so my point isn’t to beat a dead horse on this topic. I just thought I would show my graph data from my first rain event this evening. It basically rained according to the sky at a rate of just over 1" per hour but only rained for 12 minutes. The total was 1.07" which clearly is too high. I don’t have another gauge that I was able to compare it to other than radar estimates. Anyway, I just wanted to see if the calibration was going to come in a firmware update, or if there was something specifically needed for my station? Also, you may be capturing this data automatically from all stations and analyzing it, but if not, here is some more data for you to look at. I love this product and look forward to seeing some of the minor kinks worked out of it soon.
