<h3>SMAInverter</h3>

Module for the integration of a SMA Inverter over it's Speedwire (=Ethernet) Interface.<br>
Tested on Sunny Tripower 6000TL-20 and Sunny Island 4.4 with Speedwire/Webconnect Piggyback.
<br><br>

Questions and discussions about this module you can find in the FHEM-Forum link:<br>
<a href="https://forum.fhem.de/index.php/topic,56080.msg476525.html#msg476525">76_SMAInverter.pm - Abfrage von SMA Wechselrichter</a>.
<br><br>

<b>Requirements</b>
<br><br>
This module requires:
<ul>
    <li>Perl Module: IO::Socket::INET  (apt-get install libio-socket-multicast-perl) </li>
    <li>Perl Module: Date::Time        (apt-get install libdatetime-perl) </li>
	<li>Perl Module: Time::HiRes</li>
    <li>FHEM Module: 99_SUNRISE_EL.pm</li>
	<li>FHEM Module: Blocking.pm</li>
</ul>
<br>
<br>


<b>Definition</b>
<ul>
<code>define &lt;name&gt; SMAInverter &lt;pin&gt; &lt;hostname/ip&gt; </code><br>
<br>
<li>pin: password of the inverter. Default is 0000. <br>
         <b>inverter without webinterface:</b> The password for the inverter can be changed by "Sunny Explorer" Client Software <br>
		 <b>inverter with webinterface:</b> The password changed by the webinterface is also valid for the device definition. </li>
<li>hostname/ip: Hostname or IP-Adress of the inverter (or it's speedwire piggyback module).</li>
<li>The Speedwire port is 9522 by default. A Firewall has to allow connection on this port if present !</li>
</ul>


<b>Operation method</b>
<ul>
The module sends commands to the inverter and checks if they are supported by the inverter.<br>
In case of a positive answer the data is collected and displayed in the readings according to the detail-level. <br><br>

The normal operation time of the inverter is supposed from sunrise to sunset. In that time period the inverter will be polled.
The time of sunrise and sunset will be calculated by functions of FHEM module 99_SUNRISE_EL.pm which is loaded automatically by default.
Therefore the global attribute "longitude" and "latitude" should be set to determine the position of the solar system
(see <a href="#SUNRISE_EL">Commandref SUNRISE_EL</a>). <br><br>

By the attribute "suppressSleep" the sleep mode between sunset and sunrise can be suppressed. Using attribute "offset" you may prefer the sunrise and
defer the sunset virtually. So the working period of the inverter will be extended. <br><br>

In operating mode "automatic" the inverter will be requested periodically corresponding the preset attribute "interval". The operating mode can be
switched to "manual" to realize the retrieval manually (e.g. to synchronize the requst with a SMA energy meter by notify). <br><br>

During inverter operating time the average energy production of the last 5, 10 and 15 minutes will be calculated and displayed in the readings
"avg_power_lastminutes_05", "avg_power_lastminutes_10" and "avg_power_lastminutes_15". <b>Note:</b> To permit a precise calculation, you should
also set the real request interval into the attribute "interval" although you would use the "manual" operation mode ! <br><br>

The retrieval of the inverter will be executed non-blocking. You can adjust the timeout value for this background process by attribute "timeout". <br>
</ul>

<b>Get</b>
<br>
<ul>

  <li><b> get &lt;name&gt; data </b>
  <br><br>

  The request of the inverter will be executed. Those possibility is especifically created for the "manual" operation
  mode (see attribute "mode").
  <br>
  </li>

<br>
</ul>

<b>Attributes</b>
<ul>

  <a name="detail-level"></a>
  <li><b>detail-level [0|1|2] </b><br>
    Defines the complexity of the generated readings. <br><br>

		<ul>
		<table>
		<colgroup> <col width=10%> <col width=90%> </colgroup>
		  <tr><td> 0  </td><td>- only Power and Energy </td></tr>
		  <tr><td> 1  </td><td>- as 0, additional voltage and current </td></tr>
		  <tr><td> 2  </td><td>- all values </td></tr>
		</table>
		</ul>

  </li>
  <br>

  <a name="disable"></a>
  <li><b>disable [1|0]</b><br>
    Deactivate/activate the module.
  </li>
  <br>

  <a name="interval"></a>
  <li><b>interval </b><br>
    Request cycle in seconds. (default: 60)
  </li>
  <br>

  <a name="mode"></a>
  <li><b>mode [automatic|manual] </b><br>
    The request mode of the inverter. (default: automatic) <br><br>

		<ul>
		<table>
		<colgroup> <col width=10%> <col width=90%> </colgroup>
		  <tr><td> automatic  </td><td>- the inverter will be polled regularly as defined by attribute "interval" </td></tr>
		  <tr><td> manual     </td><td>- query only by command "get &lt;name&gt; data" </td></tr>
		</table>
		</ul>

  </li>
  <br>

  <a name="offset"></a>
  <li><b>offset &lt;0 - 7200&gt; </b><br>
    Time in seconds to forward the real sunrise respectively defer the real sunset.
    You will be able to extend the working period of the module.
  </li>
  <br>

  <a name="SBFSpotComp"></a>
  <li><b>SBFSpotComp [1|0]</b><br>
    The reading names are created like the SBFSpot-style. (default: 0)
  </li>
  <br>

  <a name="showproctime"></a>
  <li><b>showproctime [1|0]</b><br>
    Shows the processing time in background and the wasted time to retrieve inverter data. (default: 0)
  </li>
  <br>

  <a name="suppressSleep"></a>
  <li><b>suppressSleep [1|0]</b><br>
    The sleep mode (after sunset and before sunrise) is deactivated and the inverter will be polled continuously. (default: 0)
  </li>
  <br>

  <a name="target-serial"></a>
  <li><b>target-serial </b><br>
    In case of a Multigate the target serial number has to be defined. If more than one inverter is installed,
    you have to set the inverter serial number to assign the inverter to the device definition.
    If only one inverter available, the attribut is set automatically once the serial number of the inverter was detected.
    (default: 0xFFFFFFFF = means any serial number)
  </li>
  <br>

  <a name="target-susyid"></a>
  <li><b>target-susyid </b><br>
    In case of a Multigate the target SUSyID has to be defined. If more than one inverter is installed,
    you have to set the inverter-SUSyID to assign the inverter to the device definition.
    If only one inverter available, the attribut is set automatically once the SUSyID of the inverter was detected.
    (default: 0xFFFF = means any SUSyID)
  </li>
  <br>

  <a name="timeout"></a>
  <li><b>timeout </b><br>
    Setup timeout of inverter data request in seconds. (default 60)
  </li>
  <br>

<br><br>

<b>Voraussetzungen</b>
<br><br>
Dieses Modul benötigt:
<ul>
    <li>Perl Modul: IO::Socket::INET   (apt-get install libio-socket-multicast-perl) </li>
    <li>Perl Modul: Datetime           (apt-get install libdatetime-perl) </li>
	<li>Perl Modul: Time::HiRes</li>
    <li>FHEM Modul: 99_SUNRISE_EL.pm</li>
	<li>FHEM Modul: Blocking.pm</li>
</ul>
<br>
<br>

<b>Definition</b>
<ul>
<code>define &lt;name&gt; SMAInverter &lt;pin&gt; &lt;hostname/ip&gt;</code><br>
<br>
<li>pin: Passwort des Wechselrichters. Default ist 0000. <br>
         <b>Wechselrichter ohne Webinterface:</b> Das Passwort kann über die Client Software "Sunny Explorer" geändert werden. <br>
         <b>Wechselrichter mit Webinterface:</b> Das im Webinterface geänderte Passwort gilt auch für die Devicedefinition. </li>
<li>hostname/ip: Hostname oder IP-Adresse des Wechselrichters (bzw. dessen Speedwire Moduls mit Ethernetanschluss) </li>
<li>Der Speedwire-Port ist 9522. Dieser Port muss in der Firewall freigeschaltet sein !</li>
</ul>

<b>Arbeitsweise</b>
<ul>
Das Modul schickt Befehle an den Wechselrichter und überprüft, ob diese unterstützt werden.<br>
Bei einer positiven Antwort werden die Daten gesammelt und je nach Detail-Level in den Readings dargestellt. <br><br>

Die normale Betriebszeit des Wechselrichters wird in der Zeit vom Sonnenaufgang bis Sonnenuntergang angenommen. In dieser Periode werden die Wechselrichterdaten
abgefragt. Die Ermittlung von Sonnenaufgang / Sonnenuntergang wird über die Funktionen des FHEM-Moduls 99_SUNRISE_EL.pm vorgenommen. Zu diesem Zweck sollten die globalen
Attribute longitude und latitude gesetzt sein um den Standort der Anlage genau zu ermitteln. (siehe <a href="#SUNRISE_EL">Commandref SUNRISE_EL</a>) <br><br>

Mit dem Attribut "suppressSleep" kann der Schlafmodus unterdrückt werden. Das Attribut "offset" dient dazu den effektiven Zeitpunkt des Sonnenaufgangs / Sonnenuntergangs
um den Betrag "offset" vorzuziehen (Sonnenaufgang) bzw. zu verzögern (Sonnenuntergang) und somit die Abfrageperiode des Wechselrichters zu verlängern. <br><br>

Im Betriebsmodus "automatic" wird der Wechselrichter entsprechend des eingestellten Attributs "interval" abgefragt. Der Betriebsmodus kann in "manual"
umgestellt werden um eine manuelle Abfrage zu realisieren (z.B. Synchronisierung mit einem SMA Energymeter über ein Notify). <br><br>

Während der Betriebszeit des Wechselrichters wird die durchschnittliche Energieerzeugung der letzten 5, 10, 15 Minuten berechnet und in den Readings
"avg_power_lastminutes_05", "avg_power_lastminutes_10" und "avg_power_lastminutes_15" ausgegeben. <b>Hinweis:</b> Um eine korrekte Berechnung zu
ermöglichen, sollte auch im Betriebsmodus "manual" das tatsächliche Abfrageinterval im Attribute "interval" hinterlegt werden ! <br><br>

Die Abfrage des Wechselrichters wird non-blocking ausgeführt. Der Timeoutwert für diesen Hintergrundprozess kann mit dem Attribut "timeout" eingestellt werden. <br>

</ul>

<b>Get</b>
<br>
<ul>

  <li><b> get &lt;name&gt; data </b>
  <br><br>

  Die Datenabfrage des Wechselrichters wird ausgeführt. Diese Möglichkeit ist speziell für den Betriebsmodus "manual"
  vorgesehen (siehe Attribut "mode").
