SteelSeries JavaScript Gauges

Quick Start Guide for Cumulus Users

1. Copy "realtimegaugesT.txt" to your Cumulus web folder.
2. Copy "gauges-ssT.htm" to your Cumulus web folder.
3. Configure Cumulus Internet|Files to:

   realtime file:-
    Local filename  = <path>\Cumulus\web\realtimegaugesT.txt
    Remote filename = <website_root_path>/realtimegauges.txt
    Process = Yes
    Realtime = Yes
    FTP = Yes (unless you are local hosing)
gauges HTML file:-
    Local filename  = <path>\Cumulus\web\gauges-ssT.htm
    Remote filename = <website_root_path>/gauges-ss.htm
    Process = Yes
    Realtime = No
    FTP = Yes (unless you are local hosing) 

NOTE: Cumulus does not actually update any data when it processes the web page, it simply replaces the 'static-ish' values such as your station name, location, version etc. If you wish you can edit the .htm file and directly enter the information, then you do not need to get Cumulus to process the file, just copy it once to your web site, removing the 'T' from the filename.

1. If required edit the "gauges.js", the key items are at the top:

   - The relative path on your website to the "realtimegauges.txt" file.
 - The relative path on your website to your 'trend' graphs folder.
 - The relative path on your website to your old 'gauges' page. (users with 'old' browsers will be redirected to this page)

1. If you do not require the UV/Solar Index gauges, then change the lines

   showUvGauge : true,
 showSolarGauge : true,
to
 showUvGauge : false,
 showSolarGauge : false,

1. If you have installed to a web folder different from your Cumulus 'root' you will also need to edit the "gauges-ss.html" file, and amend the relative path to your Cumulus "weatherstyle.css" file.

Relative Paths :
Are just that, they specify where something is on your web site folder
structure relative to the page you are currently displaying.
So if you copy these gauges to a folder called 'gauges-ss' in the root of
your website, and upload the "realtimegauges.txt" to the root folder; the
relative path of the .txt file is one folder back in the path. You would
then enter the path as "../realtimegauges.txt".
If the .txt file is uploaded to the same folder as the gauges page, then the
relative path is the same folder, and you would just enter "realtimegauges.txt"

Copy (or move) the folders 'css' and 'scripts' and their contents (the files
that are contained in the ZIP file) to the folder where your "gauges-ss.htm" file is
located (probably the same folder where all your other Cumulus HTM files are located).

What Next?

After you get your new gauges page up and running, you will probably want to make it the
default gauges page on your web site. So assuming you are running the 'standard' Cumulus
web pages (if not then you can figure all this stuff out for yourself), you will need to
edit all the Cumulus supplied template files.

These files reside in your "<path to cumulus>\cumulus\web" folder. You will need to edit
each xxxxxT.htm file, and near the bottom change the link from "gauges.htm" to "gauges-ss.htm"
(also include the path if you have installed the SS gauges into a subfolder from you main
Cumulus web site).

Next time Cumulus updates your web site, the links on all your existing pages should now
point to the new SS gauges.

It is as well to leave the original gauges page on your site, the new page will direct
any really old incompatible browsers back to the original page.

Browser Redirects

If you want to redirect browsers that do not have scripting enabled, then you will have to do this in the HTML file itself. In the header section add the following code:

 <noscript>
 <meta http-equiv="refresh" content="3; url=index.htm"/>
 </noscript>

Obviously with the url changed to where ever you want the redirect pointing.

Changing Languages

To switch statically, you need to edit the "gauges.js" file, and change the line 12:

   var strings = LANG.EN,
 to
   var strings = LANG.XX,
 (where XX is the desired language code). 

To add a new translation, edit the "language.js" file and copy one of the existing sections e.g. English, to the end of the file, changing all the LANG.EN values to LANG.XX (where XX is the code for the new language), and editing all the strings. The zip file contains a language.js file with English, French, German, Dutch, Swedish, Danish, Finnish, Norwegian, Italian, Spanish, and Catalan translations to get you going.

If you are only going to use one language, then deleting the unused language options and the changeLang() function from the language.js file will speed up the page load time slightly.

To switch languages dynamically, you need to add script to your page which sets the LANG object to equal the desired language and then calls the changeLang() function. e.g.

   // Dynamic script to change the default language to German
   changeLang(LANG.DE); 

This will re-label all the gauges, and update the text/radio buttons etc. on the web page.

However, changing the language for the gauges DOES NOT translate the displayed forecast as the text of the message is being supplied by your weather station/software.

Forecast Messages

By default for Cumulus the <#forecastenc> message is displayed which shows either the Cumulus
generated forecast or the external station generated forecast depending on how Cumulus is configured.
Starting with version 1.9.2 Cumulus has additional forecast message options:
<#cumulusforecastenc> - Always displays the Cumulus generated Zambretti forecast
<#wsforecastenc> - Always displays the external weather station forecast

If you wish to use one of these options, then you should edit the "realtimegaugesT.txt" file
and replace the '<#forecastenc>' tag with the one of your choice.

NOTE: If your forecast messages use accented characters (or any character not in the basic 103
characters in the LCD font), then I recommend that you disable the digital font on the status/forecast
display. Set the following in gauges.js:

digitalForecast : false,

Weather Display users have different options for the forecast message to be used. By default the
ccrlocal file uses the Davis VP %vpforecasttext% tag. Change this to what suits you best:

%vpforecasttext% Davis VP forecast
 %forecasticonword% Words for the (Davis?) forecast icon
 %dailywarning/forecast% forecast from input daily weather

Adding Logo's/Custom Images to the Gauge Backgrounds

The supplied code contains some commented out instructions to add a small logo to the temperature
gauge, and a larger image to the DewPoint gauge. These will probably be removed by most people,
they are added to demonstrate how to use this feature. See the comments in gauges.js about
removing/adding these logos.

In order to let the gauge background appear through your images you should make them
semi-transparent, which means saving them as PNG files.

The SteelSeries code will clip your images if they exceed the gauge background area, I suggest you
size the images similar to your desired gauage size. The code will resize the image to fit the
whole background, so it you want to retain the aspect ratio make your images square!

Adding a Wind Rose 'gauge'

From release 2.0 I have integrated the Wind Rose 'gauge' into the standard 'package' but it is disabled
by default. To enable the Wind Rose you have to make the following changes...

1. Edit gauges-ssT.htm and remove the comment from around the 'radar' scripts towards the end of the
document. Change...
<!--
<script src="scripts/windrose.js"></script>
<script src="scripts/RGraph.common.core.min.js"></script>
<script src="scripts/RGraph.radar.min.js"></script>
-->
To...
<script src="scripts/windrose.js"></script>
<script src="scripts/RGraph.common.core.min.js"></script>
<script src="scripts/RGraph.radar.min.js"></script>

2. Edit gauges.js, and change...
showRoseGauge : false,
To...
showRoseGauge : true,

That's it, the Wind Rose should now display on your page.

Altering the gauge 'layout' on the page

It is easy to 'move' the gauges around the page to create alternative layouts. By default, there are
four rows of gauges laid out like this (o = optional gauge)...

• • • 
      * * o
      * * *
      o o

To move the gauges you just need to edit the HTML file and move <div>'s (and their contents) with a
class="gauge". Each 'row' is contained within a <div> with a class="row". If you do re-order the
gauges, then DO NOT change the "tip_N" numbers, each number is associated with a particular gauge not
it's position on the page.

I use the following 'horizontal' layout on my personal page (no Solar or UV optional gauges, but with
the optional Wind Rose)

• • • • 
        * * * * o

Weather Display Users

These files will work with WD if you switch the variable g_weatherProgram at the top of gauges.js to
have a value of 1. This will make the script use the WD customclientraw.txt file rather than the Cumulus
realtimegauges.txt file. A template for this file suitable for processing by WD is provided in the
zip file - customclientrawlocal.txt

The provided HTML files gauges-ssT.htm etc, are designed to be 'processed' by Cumulus before uploading
to the web site and renaming as gauges-ss.htm
This processing replaces all the tags like <#location> with general information about your station (the
station name) in this case.

To use the templates with WD you will have to manually edit the HTML file, and replace each of these tags
with information appropriate to you. I suggest you then save the file as gauges-ss.htm

You will also want to replace the Menu bar at the bottom of the HTML page which is specific to the Cumulus
sample web pages.

customclientrawlocal.txt

The value for Humidex is set to Celcius by default. You may want to change this
tag from %humidexcelsius% to %humidexfaren% if you use Farenheit as your temperature
scale. (there is no WD tag to report the value in your default scale). This and the forecast tag (see above)
are the only things you should have to edit in the ccr file.
