Rainfall reverts to 12am rollover when downloaded to Cumulus

[RWMD]

I have a Vantage Vue, and also run WLIP with it, as I like having the weather website that it automatically uploads to. However, I also run Cumulus - v1.9.2 / build 1019 (not at the same time), and when I download my console info to Cumulus, the rainfall initially downloads correctly, then after a couple of mins it changes to the 'midnight' rollover, even though I have 9am rollover time selected in the configuration section etc, and my rainfall amounts end up with negatives etc next to them.

I realise that the Davis station doesn't have an 9am rollover option - is this the reason why it does this?

Any help would be much appreciated please!

There was a problem with monthly rainfall total for 0900 rollover introduced at some point in 1.9.2., which I fixed in build 1020 - see the announcement on Nov 1st. It would be a good idea to install that, as it does affect you. But I assume it's not the monthly total you're having problems with? If you zip up the diags folder and attach it, I'll see if I can see what's going on.

Thanks Steve I had installed the new version - forgive me for sounding stupid, but how do I "zip my diags file"?

It's a folder in the Cumulus installation folder. Right-click on it and select Send To -> Compressed (zipped) folder. This will create a diags.zip file; attach it to a reply.

Attached for you Steve.

Cumulus uses the annual rain counter from the VP2 to track rainfall. When it has to use logger data, it doesn't have access to the annual counter so it has to maintain the counter from the individual totals in the logger entries. When you started it at 0716 on the 25th, the last time it had run was 2030 on the 23rd, and at that time the counter was 693.8:

25/11/2011 07:16:35.652 : Read today file: Date = 24/11/2011, LastUpdateTime = 23/11/2011 8:30:00 PM
25/11/2011 07:16:35.656 : Todayfileraindaystart = 693.799987792969

It then read the logger entries to fill in the missing data, adding the rainfall totals from the logger entries. The entries with non-zero rain counts were:

At the end of processing the logger data, the calculated total is 719.4mm. However, the station's record of the value is 704.2, which is 15.2mm less than the value Cumulus calculated from the rainfall data in the logger entries.

25/11/2011 07:17:05.297 : VP2: Setting raintotal from current station value: 704.200012207031

So this is why the rainfall total in Cumulus went wrong, because the station disagreed with the figure that Cumulus had calculated, based on the data that the station gave it. I can't go back any earlier to see where the original total came from, so I don't know whether the disagreement actually occurred earlier than this. There is no indication that Cumulus has done anything wrong.

You don't seem to have had any rain since then, and the station and Cumulus are apparently keeping in step.

I think the best course of action is to wait until you have more rain, and if the counters get out of step again, immediately zip up the diags folder and attach it here.
