Different gusts between cumulus and utils

[stephtc]

Hello, sorry this is my 1st report, I have erroneous gusts between cumulus and the Utils site is this normal?
Cumulus takes into account my gusts but the gusts that are in utils are generally much lower why?

Thank you so much

Both for the dashboard as for the charts the gusts values come directly from CMX (i.e. taken from realtime.txt and from the winddata.json).
Could you specify what the difference is? (through screenshot or description?)

One of the main differences is that the refresh rate of the interface is much higher than on the CUtils website (which follows the realtime and interval - for the charts - frequencies).

I'll be out of the loop for a week, maybe somebody else can comment here.

Good morning,

thank you for the quick response so this may be normal in this case

I made a table on purpose to show the difference over the last 11 days.

OK, 1 hr left

Where do you read those values (both in CMX and CUtils) and at what time?
Why does the CUtils gust not have one decimal?

[HansR]

To be clear: If I read yesterdays value of wind/gust in the interface (Today/Yesterday) I see the same values as in the CUtils YADR report.

Ah... and question: where are you located and what unit do you use (imperial units may have deviations in decimals used because nobody uses those and therefore they are not properly checked).

If you are interested in using imperial we may need to communicate to identify and solve those issues (specifically decimals and conversion at some places).

Do you have a URL of your site?

[stephtc]

Indeed in the CutilsYadr the gusts are exact.
But utils in the graph.php is where it's not good why I don't know.
On the other hand, there have never been decimals, is there an adjustment to be made?

I'm new to this so sorry if I don't understand everything.

[HansR]

Ok. Missed your replies, now 'en route'.
Could you answer the question on units?
Back in a week or so.

[stephtc]

Yes sorry, no worries replies in a week or two
And i am using GW1100 with raspberry
And I am located in Belgium

[HansR]

And the units (m/s, mph... Etc ..)?

[stephtc]

Oh sorry it's in metric km/h

[HansR]

Ok, thats the same as I use myself and I have correct decimals. So I really need to look into this later

[stephtc]

Ok no worries, thank you already for enlightening me

[HansR]

I have two additional remarks:

1. Did you set the number of decimals for the windspeeds to 1? (in Station Settings=>General Settings=>Units=>Advanced Options NOTE the Here be dragons! remark). I advise you do that.
2. Your remark that the chart does not show the figures of the YADR report comes probably from the zoom setting you applied. If you zoom in until you have the minute values shown i.s.o. the summarized values which the chart makes on higher zoom levels you will find that the numbers in the chart correspond to the numbers in the yadr report.

I assume this explains your question on the differences in what you see.
If you still note discrepancies let me know.

Good morning,
thanks again for your feedback.
Indeed in (in Station Settings=>General Settings=>Units=>Advanced Options) it was on 0 I just modified it.
And so utils values have decimals now.

And ok for the graph I'll wait a bit for the decimals to be well encoded and I'll look at that.

thanks again
