<br>
<a name="EGPM2LANdefine"></a>
<b>Define</b>
<ul>
<code>define &lt;name&gt; EGPM2LAN &lt;IP-Address&gt;</code><br>
<br>
Creates a Gembird &reg; <a href="http://energenie.com/item.aspx?id=7557" >Energenie EG-PM2-LAN</a> device to switch up to 4 sockets over the network.
If you have more than one device, it is helpful to connect and set names for your sockets over the web-interface first.
The name settings will be adopted to FHEM and helps you to identify the sockets. Please make sure that you&acute;re logged off from the Energenie web-interface otherwise you can&acute;t control it with FHEM at the same time.<br>
Create a <a href="#EGPM">EGPM-Module</a> to control a single socket with additional features.<br>
<b>EG-PMS2-LAN with surge protector feature was not tested until now.</b>
</ul><br>
<a name="EGPM2LANset"></a>
<b>Set</b>
<ul>
<code>set &lt;name&gt; password [&lt;one-word&gt;]</code><br>
Encrypt and store device-password in FHEM. Leave empty to remove the password.<br>
Before 04/2017, the password was stored in clear-text using the DEFINE-Command, but it should not be stored in the config-file.<br>
<br>
<code>set &lt;name&gt; &lt;[on|off|toggle]&gt &lt;socketnr.&gt;</code><br>
Switch the socket on or off.<br>
<br>
<code>set &lt;name&gt; &lt;[on|off]&gt &lt;all&gt;</code><br>
Switch all available sockets on or off.<br>
<br>
<code>set &lt;name&gt; &lt;staterequest&gt;</code><br>
Update the device information and the state of all sockets.<br>
If <a href="#autocreate">autocreate</a> is enabled, an <a href="#EGPM">EGPM</a> device will be created for each socket.<br>
<br>
<code>set &lt;name&gt; &lt;clearreadings&gt;</code><br>
Removes all readings from the list to get rid of old socketnames.
</ul>
<br>
<a name="EGPM2LANget"></a>
<b>Get</b>
<ul><code>get &lt;name&gt; state</code><br>
Returns a text like this: "1: off 2: on 3: off 4: off" or the last error-message if something went wrong.<br>
</ul><br>
<a name="EGPM2LANattr"></a>
<b>Attributes</b>
<ul>
<li>stateDisplay</li>
Default: <b>socketNumer</b> changes between <b>socketNumer</b> and <b>socketName</b> in front of the current state. Call <b>set statusrequest</b> to update all states.
<li>autocreate</li>
Default: <b>on</b> <a href="#EGPM">EGPM</a>-devices will be created automatically with a <b>set</b>-command.
Change this attribute to value <b>off</b> to avoid that mechanism.
<li><a href="#loglevel">loglevel</a></li>

<b>Define</b>
<ul>
<code>define &lt;name&gt; EGPM2LAN &lt;IP-Address&gt;</code><br>
<br>
Das Modul erstellt eine Verbindung zu einer Gembird &reg; <a href="http://energenie.com/item.aspx?id=7557" >Energenie EG-PM2-LAN</a> Steckdosenleiste und steuert 4 angeschlossene Ger&auml;te..
Falls mehrere Steckdosenleisten &uuml;ber das Netzwerk gesteuert werden, ist es ratsam, diese zuerst &uuml;ber die Web-Oberfl&auml;che zu konfigurieren und die einzelnen Steckdosen zu benennen. Die Namen werden dann automatisch in die
Oberfl&auml;che von FHEM &uuml;bernommen. Bitte darauf achten, die Weboberfl&auml;che mit <i>Logoff</i> wieder zu verlassen, da der Zugriff sonst blockiert wird.
</ul><br>
<a name="EGPM2LANset"></a>
<b>Set</b>
<ul>
<code>set &lt;name&gt; &lt;[on|off|toggle]&gt &lt;socketnr.&gt;</code><br>
Schaltet die gew&auml;hlte Steckdose ein oder aus.<br>
<br>
<code>set &lt;name&gt; &lt;[on|off]&gt &lt;all&gt;</code><br>
Schaltet alle Steckdosen gleichzeitig ein oder aus.<br>
<br>
<code>set &lt;name&gt; password [&lt;mein-passwort&gt;]</code><br>
Speichert das Passwort verschl&uuml;sselt in FHEM ab. Zum Entfernen eines vorhandenen Passworts den Befehl ohne Parameter aufrufen.<br>
Vor 04/2017 wurde das Passwort im Klartext gespeichert und mit dem DEFINE-Command &uuml;bergeben.<br>
<br>
<code>set &lt;name&gt; &lt;staterequest&gt;</code><br>
Aktualisiert die Statusinformation der Steckdosenleiste.<br>
Wenn das globale Attribut <a href="#autocreate">autocreate</a> aktiviert ist, wird f&uuml;r jede Steckdose ein <a href="#EGPM">EGPM</a>-Eintrag erstellt.<br>
<br>
<code>set &lt;name&gt; &lt;clearreadings&gt;</code><br>
L&ouml;scht alle ung&uuml;ltigen Eintr&auml;ge im Abschnitt &lt;readings&gt;.
</ul>
<br>
<a name="EGPM2LANget"></a>
<b>Get</b>
<ul><code>get &lt;name&gt; state</code><br>
Gibt einen Text in diesem Format aus: "1: off 2: on 3: off 4: off" oder enth&auml;lt die letzte Fehlermeldung.<br>
</ul><br>
<a name="EGPM2LANattr"></a>
<b>Attribute</b>
<ul>
<li>stateDisplay</li>
Default: <b>socketNumer</b> wechselt zwischen <b>socketNumer</b> and <b>socketName</b> f&uuml;r jeden Statuseintrag. Verwende <b>set statusrequest</b>, um die Anzeige zu aktualisieren.
<li>autocreate</li>
Default: <b>on</b> <a href="#EGPM">EGPM</a>-Eintr&auml;ge werden automatisch mit dem <b>set</b>-command erstellt.
