<h3>exportdevice</h3>
<ul>
  <code>exportdevice [devspec] [quote]</code>
  <br><br>
  Output a complete device and attribute definition of FHEM devices. This is
  one of the few commands which return a string in a normal case.<br>
  See the <a href="#devspec">Device specification</a> section for details on
  &lt;devspec&gt;.
  <br><br>
  The output can be used for reimport using FHEMWEB or telnet command line.<br>
  The optional paramter "quote" may be added to receive fhem.cfg compatible output.
  <br><br>

  Example:
  <pre><code>  fhem> exportdevice Office

# 
# Export created by fhem.pl:12022/2016-08-21 
# on 2016-08-22 01:02:59

<a name="exportdevice"></a>
<h3>exportdevice</h3>
<ul>
  <code>exportdevice [devspec] [quote]</code>
  <br><br>
  Gibt die komplette Definition und Attribute eines FHEM Ger&auml;tes aus. Dies
  ist eines der wenigen Befehle, die im Normalfall eine Zeichenkette ausgeben.<br>
  Siehe den Abschnitt &uuml;ber <a href="#devspec">Ger&auml;te-Spezifikation</a>
  f&uuml;r Details der &lt;devspec&gt;.
  <br><br>
  Die Ausgabe kann f&uuml;r einen Reimport mittels FHEMWEB oder Telnet
  Kommandozeile verwendet werden.<br>
  Der optionale Parameter "quote" kann genutzt werden, um eine fhem.cfg
  kompatible Ausgabe zu erhalten.
  <br><br>
  Beispiel:
  <pre><code>  fhem> exportdevice Office

# 
# Export created by fhem.pl:12022/2016-08-21
