Yesterday...

[Hoppity]

Reading the Wiki, it seems that the Yesterday file is supposed to be what it says on the tin. But when I close Cumulus to edit incorrect rain values in Today and open the programme again, Today has been copied into Yesterday, wreaking more havoc and seemingly creating negative rain values.

No doubt I am making some obvious mistake...

The today.ini values get copied to yesterday.ini at midnight, assuming that's your 'rollover' time. Note that 'midnight' can happen at any time of day at start up, if it's downloaded entries from the logger. So today.ini and yesterday.ini correspond to the last time that Cumulus was running (assuming that you haven't edited them to change that). It sounds like you were editing today.ini but Cumulus hadn't actually got to today yet?

If you zip up the diags folder together with today.ini, yesterday.ini, and Feb11log.txt and tell me exactly what you did, I'll have a look to see what happened.

That's really kind but I've messed around so much that I think it's unfair to load the burden on someone else. My graphs, apart from today's imaginary biblical deluge (and yesterday's negative rain - and I did follow the instructions on that but it just reinstated itself), now make sense again. There was a whole duplicated section in the log file which I don't think had anything to do with me, apart from the 46mm of rain between 1430 and 1500. The current values will soon be lost in the mists of time.

I do think, however, that a simple utility to reconstruct the other files from the log files would be a help to idiots like me.

Cheers,

It sounds like it's gone back and downloaded data from the logger again, which is why the changes you did didn't work. The only way I can think of that it would do that would be if the 'Timestamp' value in today.ini was changed.
