Hi, Chris You're on the right track. Generally, the database should store the number of counts in the archive interval. So, each loop packet should contain the number of counts since the last loop packet --- generally a small number.
To plot, aggregate over a time period, using aggregation type 'sum', so you're plotting, say, the number of counts per hour. This is much like the way rain is treated, except it's unit-less. As for which observation type to use, you can use any of the free types. The unit group is just used to pick appropriate unit labels in the plots and templates. But, you can always override that either in skin.conf, or in the template. Hope this helps. -tk -tk On Sat, Nov 11, 2017 at 4:05 PM, <[email protected]> wrote: > Hi All, > > I'm back working on my crawl space 'weather' system, and trying to > figure out how to map another > value.
