I looked in the today.ini and cumulus.009 diag files: Start 125,6999999... Yesterday 24,60 125,699/0,254=494,878 --> is not a multiple of 0.254 24,60/0,254=96,851 --> is not a multiple of 0.254 Since Cumulus takes these values from the DLL, I think that the problem is in the DLL. So I think there...

Today it happened again: daily rain of Cumulus: 5,4mm; WL&VWS 5,33. Same total rain, 131,1 Cumulus and 131,06 WL&VWS. I looked in the today.ini and cumulus.009 diag files: Start 125,6999999... Yesterday 24,60. WL&VWS: Start 125,73, yesterday 24,64. Now: for Cumulus actual rain= 131,1-125...

Very clear, thank you. If that's the case, I think that adding decimal places is not very useful beyond to avoid rounding. However, even today it continues to rain and the rounding is right. I really think it was a startup problem, but I'll let you know in the next few days. See you soon and thanks ...

Sorry Steve, you've intrigued me and, if I can, I take this opportunity. I had a doubt. What you mean by DLL? The data logger? I ask because now I do not understand how WeatherLink works. The data logger stores only the number of "ticks" of the pluviometer and then WeatherLink associate 0....

In the rain database of WeatherLink I have always found two decimal places, even when I used the metric tip. So it is likely that the DLL Davis always use two decimal places, in fact even VWS for default always show two decimal places. It would be interesting to see the Cumulus calculation without r...

It's done with whatever value it gets from the Davis DLL. The start of day figure is logged in today.ini without rounding. Rounding only occurs when the figure is displayed or written to the log file. In this case, the problem should not exist. I'm beginning to think that it was a problem due to th...

It may be relevant that Cumulus calculates today's rain by taking the difference between the annual rain total now and the value at the start of day. The calculation is done before rounding. But the annual rain total is downloaded every time from the datalogger? The calculation is done using the sa...

Piero

Are you an engineer too? I did a random sample. :lol: Yesterday, WeatherLink showed 0.25 (0,3 in the bulletin) and Cumulus 0.2. WeatherLink 0.76 and Cumulus 0.7. That's why I thought Cumulus would show only the first decimal place without rounding. Today, however, WeatherLink shows 8.89 and Cumulus ...

Not currently, no. Note that displaying two decimals for rain implies that your rain gauge is accurate to 0.01 mm, which it is not. It 's true, but my rain gauge is set to 0.01 inches and the display is in mm. So the problem is the conversion from inches to mm: WeatherLink uses two decimal places, ...

Piero

Hi Steve,
on my Davis station I use the weight for the measurement in inches, but the software is set to display the measurement in mm.
This fact, however, causes problems of conversion and rounding of numbers.
Can I wiew the rain with two decimal places instead of one?

Thanks and best regards

Piero

Ok Mark, I could test it just now with 20 mm/h as maximum scale's value. Now it works fine.

Piero

I'm trying now the version 2.4.4 but it does not happen to me

Piero

Perfect. I'll give you gladly confirmation just tested.

Piero

the mystery is solved, Mark. The error occurs only when the scale has maximum value higher than 10 mm / h (initial value).

Piero

Piero

Thanks Mark.
What you say is true, in fact, in previous versions, I had never noticed. Yet has been doing so the last two times it rained.
It could be a compatibility issue with firefox 23.0?
