<h3>UWZ</h3>
<ul>
   <a name="UWZdefine"></a>
   This modul extracts thunderstorm warnings from <a href="http://www.unwetterzentrale.de">www.unwetterzentrale.de</a>.
   <br/>
   Therefore the same interface is used as the Android App <a href="http://www.alertspro.com">Alerts Pro</a> does.
   A maximum of 10 thunderstorm warnings will be served.
   Additional the module provides a few functions to create HTML-Templates which can be used with weblink.
   <br>
   <i>The following Perl-Modules are used within this module: HTTP::Request, LWP::UserAgent, JSON, Encode::Guess, Text::Iconv und HTML::Parse</i>.
   <br/><br/>
   <b>Define</b>
   <ul>
      <br>
      <code>define &lt;Name&gt; UWZ [CountryCode] [AreaID] [INTERVAL]</code>
      <br><br><br>
      Example:
      <br>
      <code>
        define Unwetterzentrale UWZ UK 08357 1800<br>
        attr Unwetterzentrale download 1<br>
        attr Unwetterzentrale humanreadable 1<br>
        attr Unwetterzentrale maps eastofengland unitedkingdom<br><br>
        define UnwetterDetails weblink htmlCode {UWZAsHtml("Unwetterzentrale")}<br>
        define UnwetterMapE_UK weblink htmlCode {UWZAsHtmlKarteLand("Unwetterzentrale","eastofengland")}<br>
        define UnwetterLite weblink htmlCode {UWZAsHtmlLite("Unwetterzentrale")}
        define UnwetterMovie weblink htmlCode {UWZAsHtmlMovie("Unwetterzentrale","clouds-precipitation-uk")}
      </code>
      <br>&nbsp;

      <li><code>[CountryCode]</code>
         <br>
         Possible values: DE, AT, CH, UK, ...<br/>
         (for other countries than germany use SEARCH for CountryCode to start device in search mode)
      </li><br>
      <li><code>[AreaID]</code>
         <br>
         For Germany you can use the postalcode, other countries use SEARCH for CountryCode to start device in search mode. 
         <br>
      </li><br>
      <li><code>[INTERVAL]</code>
         <br>
         Defines the refresh interval. The interval is defined in seconds, so an interval of 3600 means that every hour a refresh will be triggered onetimes. 
         <br>
      </li><br>

      <br><br><br>
      Example Search-Mode:
      <br>
      <code>
        define Unwetterzentrale UWZ SEARCH<br>
      </code>
      <br>
      now get the AreaID for your location (example shows london):
      <br>
      <code>
        get Unwetterzentrale SearchAreaID London<br>
      </code>
      <br>
      now redefine your device with the outputted CountryCode and AreaID.

<h3>UWZ</h3> 
<ul>
   <a name="UWZdefine"></a>
   Das Modul extrahiert Unwetterwarnungen von <a href="http://www.unwetterzentrale.de">www.unwetterzentrale.de</a>.
   <br/>
   Hierfür wird die selbe Schnittstelle verwendet die auch die Android App <a href="http://www.alertspro.com">Alerts Pro</a> nutzt.
   Es werden maximal 10 Standortbezogene Unwetterwarnungen zur Verfügung gestellt.
   Weiterhin verfügt das Modul über HTML-Templates welche als weblink verwendet werden können.
   <br>
   <i>Es nutzt die Perl-Module HTTP::Request, LWP::UserAgent, JSON, Encode::Guess, Text::Iconv und HTML::Parse</i>.
