Re: [weewx-user] Noob question... where to find the actual data (temp) within weewx?

[gjr80]

No problems Jim, I have been using weewx for a few years now and I still 
keep learning things from the guides, particularly the Customization Guide.

Jim - you need to get yourself into the habit of always referring to the 
documentation whenever you have issues and questions with weewx - and 
especially with new releases etc as very often things may change between 
releases!!  ALWAYS read the update guide for each new release in particular 
as it will tell you what is new/fixed in the new release.  With weewx the 
documentation is worth its weight in gold and the best way of understanding 
and appreciating weewx and its possibilities is to become familiar with 
knowing at least what is within the manuals even if, when reading, things 
may not be fully understood.

Gary, Thanks! and yes I did read the entire weewx/docs guide... however it 
was very early into trying to implement weewx and before I had much 
understanding of how weewx worked. I should (and will) re-read the 
documentation now that I have a little better understanding of how things 
work.

Re: [weewx-user] Noob question... where to find the actual data (temp) within weewx?

[Andrew Milner]

The problem is that I have a horrible suspicion that not all possibilities 
are actually mentioned in the documentation at the present time  of 
course my suspicion may well be totally unjustified!!!  I am a staunch 
believer in the documentation - as you know - but I confess to missing that 
ordinal_compass one when I went looking and in fact got 
sidetracked/confused, I think, by the [[ordinates]] labels which I 
discovered whilst trying to find what "ordnates" referred to in the 
original question.

I am not aware of a single place, whenever I want more info I just go 'the dot 
code' in the Customization Guide. I don't know the reasoning behind why it is 
like it is, perhaps part historical when the suite of tags was less extensive 
than it is now, perhaps there is an expectation that if you are wanting to get 
down into rolling your own then you should do a bit of reading. Maybe there is 
a bit of 'give a man a fish and you feed him today, teach him to fish and you 
feed him for life' - if you understand the dot code structure you can work most 
anything out. I also think that a 'simple table of tags' would probably be 
anything but simple eg what does $span mean? If people have to go back to some 
descriptive text maybe they should go there to start off with. Tom and Matthew 
may have some more eloquent words, or maybe it's just a case of someone making

Re: [weewx-user] Noob question... where to find the actual data (temp) within weewx?

[Andrew Milner]

Gary - is there a list of dot options anywhere??  eg ordinal_compass was 
hard to find - I made a guess at the unit/formatting dot code being just 
.ordinate, but I was wrong!!  A complete list of tags/units/dotcodes would 
be very useful eg as an appendix maybe to the guide (or have I missed it?)

Moving on:

If I add  $ordnates.windDir to the .tmpl file should I get a Cardinal or 
Ordinal return?
Thanks again.

Re: [weewx-user] Noob question... where to find the actual data (temp) within weewx?

[Thomas Keffer]

The weewx report generator processes temp.txt.tmpl to produce a file
temp.txt, which will contain the current temperature as a string.

It has nothing to do with the shell.

Take a look in /var/www/html/weewx/temp.txt

Re: [weewx-user] Noob question... where to find the actual data (temp) within weewx?

[Jim W.]

As I understand it, $current.outTemp represents a string variable the value 
of which should be the outside temperature.  When I try to view the value 
(echo $current.outTemp )  I dose't work. I've tried a few other schemes as 
well, like making a shell script that does this: 
#!/bin/bash
current_outTemp=$current.outTemp
echo $current_outTemp


Can you give me an idea of how to accomplish this?

Re: [weewx-user] Noob question... where to find the actual data (temp) within weewx?

[Jim W.]

This is what I have added to skin.config


  [[ToDate]]
# Reports that show statistics "to date", such as day-to-date,
# week-to-date, month-to-date, etc.
[[[day]]]
template = index.html.tmpl


[[[temp.txt]]]
# Report that makes current outTemp availibal to other program
encoding = strict_ascii
template = temp.txt.tmpl


[[[week]]]
template = week.html.tmpl

[[[month]]]
template = month.html.tmpl

[[[year]]]
template = year.html.tmpl


Does the temp.txt.tmpl file require special formatting? Right now this is 
what it contains: 
$current.outTemp

THANKS!!!

 Jim,

 Did you check the Customizing Guide 
 ? It has an abundance of 
 information about how to access the data. As Andrew suggests, the easiest 
 is to specify that the report generator create another (tiny) file, with 
 just a single tag $current.outTemp. On every reporting cycle the tag will 
 be replaced with the current temperature.

Close.

For a simple report like this, you want "ToDate" generation (as opposed to
summaries by month or year, like the NOAA reports). So, you need to tuck
your addition under [[ToDate]] and add one more set of brackets. It will
look like:

[[ToDate]]

... (other templates)

[[[temp.txt]]]
# Report that makes current outTemp available to other program
encoding = strict_ascii
template = temp.txt.tmpl

Tom and Andrew,
I have created a new template called temp.txt.tmpl in the 
etc/weewx/skins/Standard directory. It's only content is: $current.outTemp

In the skin.conf file under [CheetahGenerator] I added:

   [[temp.txt]]
# Report that makes current outTemp available to other program
encoding = strict_ascii
template = temp.txt.tmpl

Am I on the right track? Thanks for your patience!

Re: [weewx-user] Noob question... where to find the actual data (temp) within weewx?

[Thomas Keffer]

Jim,

Did you check the Customizing Guide ?
It has an abundance of information about how to access the data. As Andrew
suggests, the easiest is to specify that the report generator create
another (tiny) file, with just a single tag $current.outTemp. On every
reporting cycle the tag will be replaced with the current temperature.
