        <br>
          Provides webhook receiver for Wifi-based weather station HP1000 and WH2600 of Fine Offset Electronics (e.g. also known as Ambient Weather WS-1001-WIFI).<br>
          There needs to be a dedicated FHEMWEB instance with attribute webname set to "weatherstation".<br>
          No other name will work as it's hardcoded in the HP1000/WH2600 device itself!<br>
          If necessary, this module will create a matching FHEMWEB instance named WEBweatherstation during initial definition.<br>
          <br>
          As the URI has a fixed coding as well there can only be one single HP1000/WH2600 station per FHEM installation.<br>
        <br>
        Example:<br>
        <div>
          <code># unprotected instance where ID and PASSWORD will be ignored<br>
          define WeatherStation HP1000<br>
          <br>
          # protected instance: Weather Station needs to be configured<br>
          # to send this ID and PASSWORD for data to be accepted<br>
          define WeatherStation HP1000 MyHouse SecretPassword</code>
        </div><br>
          IMPORTANT: In your HP1000/WH2600 hardware device, make sure you use a DNS name as most revisions cannot handle IP addresses correctly.<br>

        Enable or disable to push data forward to Weather Underground (defaults to 0=no)

      <a name="wu_realtime"></a><li><b>wu_realtime</b></li>

          Stellt einen Webhook f&uuml;r die WLAN-basierte HP1000 oder WH2600 Wetterstation von Fine Offset Electronics bereit (z.B. auch bekannt als Ambient Weather WS-1001-WIFI).<br>
          Es muss noch eine dedizierte FHEMWEB Instanz angelegt werden, wo das Attribut webname auf "weatherstation" gesetzt wurde.<br>
          Kein anderer Name funktioniert, da dieser hard im HP1000/WH2600 Ger&auml;t hinterlegt ist!<br>
          Sofern notwendig, erstellt dieses Modul eine passende FHEMWEB Instanz namens WEBweatherstation w&auml;hrend der initialen Definition.<br>
          <br>
          Da die URI ebenfalls fest kodiert ist, kann mit einer einzelnen FHEM Installation maximal eine HP1000/WH2600 Station gleichzeitig verwendet werden.<br>
        <br>
        Beispiel:<br>
        <div>
          <code># ungesch&uuml;tzte Instanz bei der ID und PASSWORD ignoriert werden<br>
          define WeatherStation HP1000<br>
          <br>
          # gesch&uuml;tzte Instanz: Die Wetterstation muss so konfiguriert sein, dass sie<br>
          # diese ID und PASSWORD sendet, damit Daten akzeptiert werden<br>
          define WeatherStation HP1000 MyHouse SecretPassword</code>
        </div><br>
          WICHTIG: Im HP1000/WH2600 Ger&auml;t selbst muss sichergestellt sein, dass ein DNS Name statt einer IP Adresse verwendet wird, da einige Revisionen damit nicht umgehen k&ouml;nnen.<br>
