Rain correction

[HansR]

I had some maintenance to the station yesterday and unfortunately I tipped the bucket several times making it register some rain.
So I tried to correct the contents:

1. I deleted about an hour from the monthly log file
2. I set all rain entries in the ini files relevat to this amount to zero or (total) substracted the value
3. I corrected the last tipping time in today.ini
4. I corrected the dayfile.txt

And still, I get the yesterday rain with the erroneous value in the realtime.txt to show up in my website and still I have a figure in the raingraph.
Where does that come from and how to clean that?

Is it maybe possible, to have an automatic rain correction in CumulusMX which makes it possible to correct a todays rain (the menu entry is already there), and have it correctly propagated through all datafiles iso having to do this manually? And if you are a bit late, have it correct yesterdays rain? Now this menu choice is a make believe something is happening which it does not.

Although https://cumuluswiki.org/a/FAQ#My_statio ... _figure.29 was written for Cumulus 1, I believe it still applies to MX. It, largely based on text by Steve Loft, explains how complex it is to correct rainfall.

Not for me to respond to.

@sfws: Thanks for the extended answer. Remind me of just pulling the plug when I do maintenance so correction is not required

I understand. And I don't expect Mark to be waiting for this type of work, but I really think it would be a useful addition.
It has happened several times to me now and the agony grows, also suspecting I am not alone.

Definitely, not alone in multiple experiences. The agony shrinks for me as I have become more tolerant of bad data since I stopped having a public web site.

You may already know this, but it is best to put your VP2 into setup mode before performing maintenance, as it stops recording data when in this mode. I find that is the best way to avoid spurious rain readings.

Yes

Yes, I know. The strange thing is I forget. Then I think: I can do this without moving the bucket. Then I think: sh*t, should have pulled the plug.
Bottom line is: it just happens sometimes but of course you are right. That is how it should be done.
