XML-Structure¶

An XML file consists of various “elements” that together represent a tree. An element can include other elements. Via “Attributes” an element can accept values. Some of these attributes must be assigned.

The Header of visu_config.xml¶

The configuration file always starts with the following two lines:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<pages xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" design="pure" xsi:noNamespaceSchemaLocation="visu_config.xsd">

The following settings are relevant in the second line:

Option	Description	Values	Necessary
`design="pure"`	This option sets the default design to apply to the visualization	pure, metal, discreet, discreet_sand, discreet_slim, alaska, alaska_slim	YES
`screensave_time="60"`	This option can be used to set the time after which a particular page is returned	any value in seconds	NO
`screensave_page="main"`	This option allows you to specify which page will be displayed after `sceensave_time` has expired	Specification of the page ID eg. “id_1” or page name e.g. “Main”	NO

Next in the visu_config.xml within the meta tag are all definitions for plugins, mappings, stylings, icons and the status bar. The correct order must be adhered to!

The following is an overview of the options in the meta-tag.

Include additional files¶

Available since version: 0.11.0

Option	Description	Values	Necessary
`<file type=" "></file>`	With this option additional files (CSS or Javascript) can be loaded	Path to the file	NO

<meta>
    <files>
        <file type="css">resource/config/media/style.css</file>
        <file type="js" content="plugin">resource/config/media/MyCustomWidget.js</file>
    </plugins>
    ...
</meta>

Plugins¶

Option	Description	Values	Necessary
`<plugin name=" "/>`	With this option the plugins are included. Here the name of the plugin is entered. For each plugin such an entry must be created.	z.B. colorchooser or diagram	NO

<meta>
    <plugins>
        <plugin name="colorchooser"/>
    </plugins>
    ...
</meta>

Mappings¶

Option	Description	Values	Necessary
`<mapping name=" ">`	This option defines the name of the mapping. This is also displayed in the web editor with corresponding widgets.	e.g. Name	YES
`<entry value="WERT">NAME</entry>`	This option assigns a name to a value. For every possible value, such an entry must be created.	e.g. Stop	YES

<meta>
    ...
    <mappings>
        <mapping name="Start/Stop">
            <entry value="0">Stop</entry>
            <entry value="1">Start</entry>
        </mapping>
    </mappings>
    ...
</meta>

Stylings¶

Option	Description	Values	Necessary
`<styling name=" ">`	This option defines the name of the styling. This is also displayed in the web editor with corresponding widgets.	e.g. name	YES
`<entry value="WERT">FARBE</entry>`	This option assigns a color to a value.	e.g. red	YES

<meta>
    ...
    <stylings>
        <styling name="RedGreen">
            <entry value="0">red</entry>
            <entry value="1">green</entry>
        </styling>
    </stylings>
    ...
</meta>

Icons¶

Option	Description	Values	Necessary
`<icon-definition name=" " uri="WERT">`	This option defines the name of the icon, which is located under the directory specified in uri. The icons defined in this way can then be accessed via the name that is easier to remember. The directory specification in the example is relative to the CV installation. Here, the icons were previously stored in a separate subdirectory.	e.g.	NO

<meta>
    ...
    <icons>
        <icon-definition name="Icon1" uri="./icon/subfolder/icon1.png"/>
    </icons>
    ...
</meta>

Hint

If the icons have been uploaded with the Manager they are stored in the path resource/config/media/. An uploaded icon with the filename logo.svg kan be included with the following line: <icon-definition name="Logo" uri="resource/config/media/logo.svg"`. The path ``resource/config/media/ is valid for CometVisu versions >=0.11.x. For versions <=0.10.x the path config/media/ is valid.

Footer¶

The status bar (footer) is located at the bottom of the screen and allows e.g. external links (via URL).

<meta>
    ...
    <statusbar>
        <status type="html"><![CDATA[
            <img src="resource/icon/comet_64_ff8000.png" alt="CometVisu" /> by <a href="http://www.cometvisu.org/">CometVisu.org</a>
            - <a href=".?forceReload=true">Reload</a>
            - <a href="?config=demo">Widget Demo</a>

        <status type="html"><![CDATA[
            - <a href="check_config.php">Check Config</a>
            <div style="float:right;padding-right:0.5em">Version: SVN</div>
            ]]></status>
    </statusbar>
</meta>

Templates¶

Available since version: 0.11.0

In the meta area, templates for frequently used configuration sections can be created. In general, one would like to show e.g. his heating in every room in the same way. However, this can consist of several widgets, e.g. a slider for displaying and operating the valve position, an info widget for displaying the current actual temperature and an InfoTrigger widget for the current setpoint temperature. This structure is the same in every room, only the used address changes. With a template you have to write this structure only once and can reuse it in every room.

In the template definition, placeholders are used for variables, which are then replaced by the corresponding values when using the template. The following example shows how to define and use a template.

Example of a template for a heater and its use in different rooms¶

<pages>
    <meta>
      <templates>
        <template name="Heating">
            <group name="Heating">
              {{{ additional_content }}}
              <slide min="0" max="100" format="%d%%">
                <label>
                  <icon name="sani_heating" />
                  Heating
                </label>
                <address transform="OH:dimmer" variant="">{{ control_address }}</address>
              </slide>
              <info format="%.1f °C">
                <label>
                  <icon name="temp_temperature" />
                  actual value
                </label>
                <address transform="OH:number" variant="">{{ currenttemp_address }}</address>
              </info>
              <infotrigger uplabel="+" upvalue="0.5" downlabel="-"
                           downvalue="-0.5" styling="BluePurpleRedTemp"
                           infoposition="middle" format="%.1f °C" change="absolute" min="15" max="25">
                <label>
                  <icon name="temp_control" />
                  setpoint
                </label>
                <address transform="OH:number" variant="">{{ targettemp_address }}</address>
              </infotrigger>
            </group>
        </template>
      </templates>
    </meta>
    <page>
        <page name="Living room">
            ...
            <template name="Heating">
              <value name="control_address">Heating_FF_Living</value>
              <value name="currenttemp_address">Temperature_FF_Living</value>
              <value name="targettemp_address">Temperature_FF_Living_Target</value>
            </template>
            ...
        </page>
        <page name="Kitchen">
            ...
            <template name="Heating">
              <value name="control_address">Heating_FF_Kitchen</value>
              <value name="currenttemp_address">Temperature_FF_Kitchen</value>
              <value name="targettemp_address">Temperature_FF_Kitchen_Target</value>
              <value name="additional_content">
                <text><label>Heating Kitchen</label></text>
              </value>
            </template>
            ...
        </page>
    </page>
</pages>

Hint

The templates use mustache.js. For more information, the mustache.js documentation can be consulted.

As an alternative to the example above, the content of the template can also be swapped out to an external file.

Example of a template definition from an external file¶

<pages>
    <meta>
      <templates>
        <template name="Heizung" ref="resource/config/media/heating.template.xml"/>
      </templates>
    </meta>
    <page>
        <page name="Living room">
            ...
            <template name="Heating">
              <value name="control_address">Heating_FF_Living</value>
              <value name="currenttemp_address">Temperature_FF_Living</value>
              <value name="targettemp_address">Temperature_FF_Living_Target</value>
            </template>
            ...
        </page>
        <page name="Kitchen">
            ...
            <template name="Heating">
              <value name="control_address">Heating_FF_Kitchen</value>
              <value name="currenttemp_address">Temperature_FF_Kitchen</value>
              <value name="targettemp_address">Temperature_FF_Kitchen_Target</value>
              <value name="additional_content">
                <text><label>Heating Kitchen</label></text>
              </value>
            </template>
            ...
        </page>
    </page>
</pages>

Content of the external file resource/config/media/heizung.template.xml¶

<group name="Heating">
  {{{ additional_content }}}
  <slide min="0" max="100" format="%d%%">
    <label>
      <icon name="sani_heating" />
      Heating
    </label>
    <address transform="OH:dimmer" variant="">{{ control_address }}</address>
  </slide>
  <info format="%.1f °C">
    <label>
      <icon name="temp_temperature" />
      actual value
    </label>
    <address transform="OH:number" variant="">{{ currenttemp_address }}</address>
  </info>
  <infotrigger uplabel="+" upvalue="0.5" downlabel="-"
                           downvalue="-0.5" styling="BluePurpleRedTemp"
                           infoposition="middle" format="%.1f °C" change="absolute" min="15" max="25">
    <label>
      <icon name="temp_control" />
      setpoint
    </label>
    <address transform="OH:number" variant="">{{ targettemp_address }}</address>
  </infotrigger>
</group>

Structure of the visu pages¶

First, a page must be created as the start page. This happens with the topmost container. All other widgets and pages are inside this main page. The position of the elements is processed from top to bottom.

This looks like this:

Mainpage with link to the subpage

subpage

...
<meta>
    <plugins>
     <plugin name="colorchooser"/>
    </plugins>
</meta>
...
<page name="Mainpage">
   <page name="Page1">
       <switch on_value="1" off_value="0">
          <label>Spot TV</label>
          <address transform="DPT:1.001" mode="readwrite" variant="">1/0/5</address>
       </switch>
   </page>
   <colorchooser>
      <label>RGB Kitchen</label>
      <address transform="DPT:5.001" mode="readwrite" variant="r">1/2/59</address>
      <address transform="DPT:5.001" mode="readwrite" variant="g">1/2/60</address>
      <address transform="DPT:5.001" mode="readwrite" variant="b">1/2/61</address>
   </colorchooser>
</page>

This little example creates a main page named Start page. On this home page, a link to a subpage named Page1 will be created. On this subpage, a button named Spot TV will be added to the top. Next, the color chooser named RGB Kitchen will be added to the main page.

With this structure arbitrarily complex page structures can be created. For a description of the individual widgets with their associated XML codes, see Widget Summary

In the last line of the config the tag has to be closed. Therefore the following entry has to be inserted at the end of the file:

</pages>

This completes the visu_config.xml and can be transferred to the server.
