<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>Define</b>
<ul>
<code>define &lt;name&gt; SMAInverter &lt;pin&gt; &lt;hostname/ip&gt; </code><br>
<br>
<li>pin: User-Password of the SMA Inverter. Default is 0000. Can be changed by "Sunny Explorer" Windows Software</li>
<li>hostname/ip: Hostname or IP-Adress of the inverter (or it's speedwire piggyback module).</li>
<li>Port of the inverter is 9522 by default. Firewall has to allow connection on this port !</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>
If more than one inverter is installed, set attributes "target-susyid" and "target-serial" with an appropriate value. <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>
<code>get &lt;name&gt; data</code>
<br><br>

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

</ul>

<b>Attributes</b>
<ul>
  <li><b>interval</b>       : Queryintreval in seconds </li>
  <li><b>detail-level</b>   : "0" - Only Power and Energy / "1" - Including Voltage and Current / "2" - All values </li>
  <li><b>disable</b>        : 1 = the module is disabled </li>
  <li><b>mode</b>           : automatic = the inverter will be polled by preset interval, manual = query only by command "get &lt;name&gt; data" </li>
  <li><b>offset</b>         : time in seconds to prefer the sunrise respectively defer the sunset virtualy (0 ... 7200).  You will be able to extend the working
                              period of the module. </li>
  <li><b>SBFSpotComp</b>    : 1 = the readings are created like SBFSpot-style </li>
  <li><b>suppressSleep</b>  : the sleep mode (after sunset, before sunrise) is deactivated and the inverter will be polled continuously.  </li>
  <li><b>showproctime</b>   : shows processing time in background and wasted time to retrieve inverter data  </li>
  <li><b>target-susyid</b>  : In case of a Multigate the target SUSyID can be defined. If more than one inverter is installed you have to
                              set the inverter-SUSyID to assign the inverter to the device definition.
                              Default is 0xFFFF, means any SUSyID</li>

<h3>SMAInverter</h3>

Modul zur Einbindung eines SMA Wechselrichters über Speedwire (Ethernet).<br>
Getestet mit Sunny Tripower 6000TL-20 und Sunny Island 4.4 mit Speedwire/Webconnect Piggyback.
<br><br>

Fragen und Diskussionen rund um dieses Modul finden sie im FHEM-Forum unter:<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>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>Define</b>
<ul>
<code>define &lt;name&gt; SMAInverter &lt;pin&gt; &lt;hostname/ip&gt;</code><br>
<br>
<li>pin: Benutzer-Passwort des SMA STP Wechselrichters. Default ist 0000. Kann über die Windows-Software "Sunny Explorer" geändert werden </li>
<li>hostname/ip: Hostname oder IP-Adresse des Wechselrichters (bzw. dessen Speedwire Moduls mit Ethernetanschluss) </li>
<li>Der Port des Wechselrichters 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>
Sind mehr als ein Wechselrichter installiert, sind die Attribute "target-susyid" und "target-serial" entsprechend zu setzen um die korrekte
Funktion zu gewährleisten. <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>
<code>get &lt;name&gt; data</code>
<br><br>

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

</ul>

<b>Attribute</b>
<ul>
  <li><b>interval</b>         : Abfrageinterval in Sekunden </li>
  <li><b>detail-level</b>     : "0" - Nur Leistung und Energie / "1" - zusätzlich Strom und Spannung / "2" - Alle Werte </li>
  <li><b>disable</b>          : 1 = das Modul ist disabled </li>
  <li><b>mode</b>             : automatic = die Wechselrichterwerte werden im eingestellten Interval abgefragt, manual = Abfrage nur mit "get &lt;name&gt; data" </li>
  <li><b>offset</b>           : Zeit in Sekunden um die der Sonnenaufgang vorgezogen bzw. Sonnenuntergang verzögert wird (0 ... 7200). Dadurch wird die 
                                effektive Aktivzeit des Moduls erweitert.  </li>
  <li><b>suppressSleep</b>    : der Schlafmodus (nach Sonnenuntergang, vor Sonnenaufgang) wird ausgeschaltet und der WR abgefragt.  </li>
  <li><b>showproctime</b>     : zeigt die für den Hintergrundprozess und die Abfrage des Wechselrichter verbrauchte Zeit.  </li>
  <li><b>SBFSpotComp</b>      : 1 = die Readings werden kompatibel zu SBFSpot-Ausgaben erzeugt </li>
  <li><b>target-susyid</b>    : Im Falle eines Multigate kann die Ziel-SUSyID definiert werden. Ist mehr als ein Wechselrichter installiert,
                                muß die Wechselreichter-SUSyID gesetzt werden um den Wechselrichter der Device-Definition eindeutig zuzuweisen.
							    Default ist 0xFFFF (=keine Einschränkung)</li>
  <li><b>target-serial</b>    : Im Falle eines Multigate kann die Ziel-Seriennummer definiert werden. Ist mehr als ein Wechselrichter installiert,
                                muß die Wechselreichter-Seriennummer gesetzt werden um den Wechselrichter der Device-Definition eindeutig zuzuweisen.
								Default ist 0xFFFFFFFF (=keine Einschränkung)</li>
