<h3>LuftdatenInfo</h3>
(en | <a href="commandref_DE.html#LuftdatenInfo"><u>de</u></a>)
<div>
  <ul>
    LuftdatenInfo is the FHEM module to read particulate matter, temperature
    and humidity values ​​from the self-assembly particulate matter sensors
    from <a href="http://Luftdaten.info"><u>Luftdaten.info</u></a>.<br>
    The values ​​can be queried directly from the server or locally.<br>
    There is an
    <a href="https://forum.fhem.de/index.php/topic,73879">
      <u>alternative Firmware</u>
    </a>
     to support more sensors.<br>
    <br>
    <b>Prerequisites</b>
    <ul>
      The Perl module "JSON" is required.<br>
      Under Debian (based) system, this can be installed using
      <code>"apt-get install libjson-perl"</code>.
    </ul>
    <br>
    <a name="LuftdatenInfodefine"></a>
    <b>Define</b>
    <ul>
      <code>
        define &lt;name&gt; LuftdatenInfo remote
          &lt;SENSORID1&gt; [&lt;SENSORID2&gt; ..]<br>
        define &lt;name&gt; LuftdatenInfo local &lt;IP&gt;<br>
        define &lt;name&gt; LuftdatenInfo
          slave &lt;master-name&gt; &lt;sensor1 sensor2 ...&gt;
      </code><br>
      To query the data from the server, all affected SensorIDs must be
      specified. The IDs of the SDS01 stands right at
      <a href="http://maps.luftdaten.info/">
        <u>http://maps.luftdaten.info/</u>
      </a>
      . The DHT22 SensorID is usually the SDS011 SensorID + 1. While parsing
      the data the location values from all sensors will be compared and a
      message will be written into the log if they differ.<br>
      For a local query of the data, the IP address or hostname must be
      specified.<br>
      If several similar sensors are used, the duplicate values can be written
      in another device.

<h3>LuftdatenInfo</h3>
(<a href="commandref.html#LuftdatenInfo"><u>en</u></a> | de)
<div>
  <ul>
    LuftdatenInfo ist das FHEM Modul um Feinstaub-, Temperatur- und
    Luftfeuchtichkeitswerte von den selbstbau Feinstaub Sensoren von
    <a href="http://Luftdaten.info"><u>Luftdaten.info</u></a> auszulesen.<br>
    Dabei k&ouml;nnen die Werte direkt vom Server oder auch lokal abgefragt
    werden.<br>
    Bei einer lokalen Abfrage werden durch eine
    <a href="https://forum.fhem.de/index.php/topic,73879">
      <u>alternative Firmware</u>
    </a>
     noch weitere Sensoren unterstützt.<br>
    <br>
    <b>Vorraussetzungen</b>
    <ul>
      Das Perl-Modul "JSON" wird ben&ouml;tigt.<br>
      Unter Debian (basierten) System, kann dies mittels
      <code>"apt-get install libjson-perl"</code> installiert werden.
    </ul>
    <br>
    <a name="LuftdatenInfodefine"></a>
    <b>Define</b>
    <ul>
      <code>
        define &lt;name&gt; LuftdatenInfo remote
          &lt;SENSORID1&gt; [&lt;SENSORID2&gt; ..]<br>
        define &lt;name&gt; LuftdatenInfo local &lt;IP&gt;<br>
        define &lt;name&gt; LuftdatenInfo
          slave &lt;master-name&gt; &lt;sensor1 sensor2 ...&gt;
      </code><br>
      F&uuml;r eine Abfrage der Daten vom Server müssem alle betroffenenen
      SensorIDs angegeben werden. Die IDs vom SDS01 stehen rechts auf der Seite
      <a href="http://maps.luftdaten.info/">
        <u>http://maps.luftdaten.info/</u>
      </a>
      . Die DHT22 SensorID entspricht normalerweise der SDS011 SensorID + 1.
      Bei einer Abfrage werden die die Positionsangaben verglichen und bei
      einer Abweichung eine Meldung ins Log geschrieben.<br>
      F&uuml;r eine lokale Abfrage der Daten muss die IP Addresse oder der
      Hostname angegeben werden.<br>
      Werden mehrere ähnliche Sensoren betrieben lassen sich die doppelten
      Werte in einem anderen Gerät geschrieben werden.
