Watson W8681

Now my pressure trend is reading +4.2 Rising Very Rapidly, and local conditions say differently
although looking at recent pressure history on station it looks steady

not seen this before i updated

Also

How do i get cumulus to create a CSV for current temperature?? say every 30 mins or so,
I would like to be able to use it with my Ham Radio Echolink Station to send local conditions over the radio

Many Thanks

It's hard to say without further information, e.g. a link to your web site, a copy of your pressure chart, or the last three hours of data from your April log file. The pressure trend is calculated from the difference between the pressure now and the pressure three hours ago. It looks like you got a bad reading either now, or then. Does your current pressure look OK? How does it compare with what it was three hours ago?

The pressure trend code hasn't changed for a long time, so this is a coincidence. It's more likely that your pressure reading was wrong, or is wrong now since the restart, possibly due to the wrong 'offset' being used before or after the restart - http://wiki.sandaysoft.com/a/FAQ#My_pre ... creased.21

If you just want the current temperature, then you could create a custom file using webtags. You'd include the current temperature (<#temp>) and anything else you wanted. You say you want a CSV file, so presumably you want other fields in there? You could then add the file you created to the 'files' tab of the internet settings, and get Cumulus to process it and ftp it to your web site (or leave it on your PC, depending on what exactly you want to do with it).

thanks for the quick reply steve, i think i know what happened, after i updated it gave the wrong pressure within cumulus, 1018 at the mo its 1012.0 so i presume its taken the trend from that wrong reading???

all seems ok now, i have restarted cumulus and its reading the correct pressure

only the trend reading 4.2 rising rapidly, so i think i should let it settle itself?


ok, i use weather exchange at the moment to output a .data.csv
that my echoproducer reads to broadcast the weather

i really would like cumulus to support this natively

could you possibly give me a idiots guide to produce a webtag if no other way is possible please

regards

Lee

i have attached 2 files one is the .csv that weather exchange produces
and NOTES is how echoproducer reads the data

http://www.lowestoftweather.info is the weather site i upload to

Yes, it looks like you did have the problem described in the FAQ.

It will correct itself three hours after that sudden change in pressure reading, so just after 16:00.

I can't tell what those fields in the CSV file are supposed to represent, but basically to get Cumulus to produce something similar you create a text file that contains web tags and commas, like this for example:

<#date>,<#timehhmmss>,<#temp>,<#press>,<#hum>

You then add this file to the files tab in the internet settings, and tick the process box. You can get Cumulus to ftp it or copy it to somewhere on your PC - see the help. The result would be a file with the actual values in, like this:

29/04/11,15:48:21,12.5,1026.7,85

You would have to use the appropriate web tags in the correct order as expected by the software that was going to use the data.
