Forecast Cumulus vs Weather station
Hey,
Ive just noticed Cumulus is saying : Mostly cloudy and cooler. Precipitation likely. Windy with possible wind shift to the W, NW, or N.
But my weather station VP2 6163: Mostly cloudy and cooler. Precipitation likely. Windy with possible wind shift to the W, SW, or S.
Has anyone else notice this, I've never seen a problem before till this one.
ps . I'm using the <#wsforecast> webtag with cumulus setting "cumulus forecast" unticked
and it's the same on the standard <#forecast> webtag
cumulus v1.9.2 (1006)

Re: Forecast Cumulus vs Weather station
This is interesting - this is exactly what beteljuice suggested might happen with Davis stations, they change the forecast wind direction like the Zambretti forecast does, based on the hemisphere that you live in. Unfortunately there's nothing I can do as the strings are supplied by the Davis DLL. They must have forgotten to do in the DLL what they do in console.

Re: Forecast Cumulus vs Weather station
I've had a look at the DLL documentation, and there are functions to read the latitude and longitude from the console. Cumulus doesn't use these, but I wonder if the DLL remembers the values and uses them to modify the forecast. I could try adding the calls, it's not too hard.

Re: Forecast Cumulus vs Weather station
Did you have any luck with this Steve? My forecast wind directions appear to be the opposite of what they should be.steve wrote:I've had a look at the DLL documentation, and there are functions to read the latitude and longitude from the console.

Re: Forecast Cumulus vs Weather station
I added the calls to read the latitude and longitude from the station some time ago, so if that hasn't helped, I can't think of anything else I can do.

Re: Forecast Cumulus vs Weather station
Thanks Steve. I'll maybe give Davis a call and see if they have a answer.

Re: Forecast Cumulus vs Weather station
I've just realised that you're not in the southern hemisphere, which is where I'd expect this issue to appear. Can you give an example of the forecast shown by Cumulus compared to the console?

Re: Forecast Cumulus vs Weather station
Steve, I just checked the forecast provided by the Vantage Pro2 console and the forecast displayed on Cumulus main screen and both are identical - station is in the northern hemisphere.

Re: Forecast Cumulus vs Weather station
The forecast on my VP2 console and the Cumulus main screen are in agreement. I'm also in the northern hemisphere.

cumulus v1.9.2 (1016)
I now have a problem.... my console forecast is no where near the same as Cumulus :S
Cumulus reads
Mostly cloudy and cooler. Windy with possible wind shift to the W, NW, or N.
my station reads
Mostly Cloudy And Cooler Windy

Re: Forecast Cumulus vs Weather station
Nowhere near the same? The "Cumulus" forecast (which is actually the Davis DLL forecast) is the same but has "with possible wind shift to the W, NW, or N" on the end.
I'm afraid there's nothing I can do if people aren't happy with the "Cumulus" forecast. Cumulus just reads it from the Davis DLL.

Re: Forecast Cumulus vs Weather station
whoops I didnt mean to word it like that sorry.
So have you done changes to Cumulus to knock the "with possible wind shift to the W, NW, or N" off the end?

Re: Forecast Cumulus vs Weather station
No; it just reads it from the DLL and displays it exactly as it receives it. But you said the console had the shorter one?Darknstormy wrote:So have you done changes to Cumulus to knock the "with possible wind shift to the W, NW, or N" off the end?
The change I did was to make the DLL read the longitude and latitude from the console, in the hope that this might make the DLL modify the wind directions as the console appears to do. I have low confidence that it will have any effect, and as beteljuice points out, how do we know it's the DLL which is wrong and not the console?
