Rain Rate
Very strange reporting as you can see today and yesterday rain rate 14.4 but graphs do not relect this and the months day file does not record 14.4 mm at 20:23 . I cannot be 100% certain but I 'm almost certain the graph did show 14.4 for yesterday prior to restarting Cumulus earlier today

Re: Rain Rate
Thinking about this a little more as the logger is set to 5 mins and the recording was 20:20 and then 20:25 the record recorded whilst Cumulus was runnning in real time means the data at 20:23 is in fact lost when Cumulus is restarted - I think this makes sense

Re: Rain Rate
Both the graphs and the monthly logs are snapshots of the values at that moment in time, so it's quite possible for the maximum rain rate not to appear in either of those. And when you restart Cumulus, the graphs are then plotted from the logs rather than the 1-minute intervals when running live, so again, it's quite possible for values that were on the graphs before a restart to not be on the graphs after a restart. I guess I should add a FAQ for this as it comes up so often (but normally peak wind gusts are the topic).
The one place where the day's maximum rain rate definitely should appear is in dayfile.txt.
