SMA Webbox

Hallo.

Hat schon jemd die SMA Webbox mit IPS verbandelt? Habe da nur einen Thread im IPS 1.x Archiv gefunden.

Grüsse.

Gelöst: Habe die Sache selber lösen können. Danke.

Hallo,

darf man mal nachfragen, wie du das gelöst hast.

Gruß
Christian

Hallo.

Es läuft noch nicht so wie ich mir das vorstelle aber ich kann die Ertragsdaten der gesamten Anlage auslesen, bisher nicht jedoch der einzelnen Wechselrichter. Da werde ich mich über Weihnachten dran setzten weil ich da etwas Zeit dafür erübrigen kann.

Grüsse.

Hallo kronos,

Über welchen Weg hast du denn das auslesen der Webbox gemacht?

Ich habe da auch was geschrieben aber es ist sehr langsam.

Hallo Dirk.

Ich frage die Webbox alle 30 Sekunden ab und benutze die Parameter wie Sie in der Doku von SMA angegeben sind. Anfangs hatte es bei mir noch mit der JSON-Geschichte gehapert aber da hat mir CGastager aufs Pferd geholfen.

Wenn ich es richtig im Kopf habe empfiehlt SMA auch nicht öfters als alle 30 Sekunden einen Zugriff auf die Betriebsdaten. Schätze mal die Webbox wird nicht allzu performant sein.

Grüsse.

Hallo,

Wenn ich json die Webbox Abfrage der Sensorbox und Wechselrichter benötigt das script ca 22-29 sec.

Beseht die Möglichkeit das du mir mal dein Script senden könntest?

Gruß
Dirk

Laufzeit bei mir zwischen 900 und 1200ms. Ist nicht hübsch aber funktioniert:

Hallo,

nutze schon einige Zeit diesen Script, leider läuft es seit der Umstellung auf IP-Symcon 2.4 nicht mehr.

Hat sich vielleicht etwas verändert?
Vielleicht beim JSON?

Viele Grüße

ASICS

Ich benutze es auch, aber ohne Fehler. Welche Fehlermeldung bekommst Du denn.

Hallo,

habe gerade mal eine andere Webbox benutzt und da geht das Skript.
Die Webbox, welche nicht will, ist aber erreichbar, ich kann mich einloggen etc.

Merkwürdig…

Fehlermeldung:

Notice: Trying to get property of non-object in…

Die betroffene Zeile:

$zustand=($response->result->overview[3]->value);

Scheint als ob keine Daten übermittelt werden.

Viele Grüße

ASICS

Ja sieht so aus.

Problem gefunden aber noch nicht ganz gelöst.

Habe die Webbox bis jetzt über die DynDNS-Adresse angesprochen - ging Wochenlang gut.

Jetzte geht es nicht mehr - es sei denn ich nehme die IP-Adresse direkt - dann geht es!

Also suche ich jetzt eine Möglichkeit die DynDNS-Adresse aufzulösen und somit die IP-Adresse für meine Anfrage zu verwenden.

Eine Idee?

Viele Grüße

ASICS

Problem gelöst:

$ip = gethostbyname („meine-Adresse.de“);

DANKE für deine Hilfe!

Hi…

versuche auch gerade das Script von Kronos einzubinden. Leider fehlt mir die JSON.ips.php. Welche habt ihr genutzt? Ist das die JSON RPC Schnittstelle von saschahb?

Hi.

Das Skript habe ich nur etwas angepasst - war von CGastager hier aus dem Forum. Die JSON.ips.php hat folgenden Inhalt:

<?php
/* vim: set expandtab tabstop=4 shiftwidth=4 softtabstop=4: */

/**
 * Converts to and from JSON format.
 *
 * JSON (JavaScript Object Notation) is a lightweight data-interchange
 * format. It is easy for humans to read and write. It is easy for machines
 * to parse and generate. It is based on a subset of the JavaScript
 * Programming Language, Standard ECMA-262 3rd Edition - December 1999.
 * This feature can also be found in  Python. JSON is a text format that is
 * completely language independent but uses conventions that are familiar
 * to programmers of the C-family of languages, including C, C++, C#, Java,
 * JavaScript, Perl, TCL, and many others. These properties make JSON an
 * ideal data-interchange language.
 *
 * This package provides a simple encoder and decoder for JSON notation. It
 * is intended for use with client-side Javascript applications that make
 * use of HTTPRequest to perform server communication functions - data can
 * be encoded into JSON notation for use in a client-side javascript, or
 * decoded from incoming Javascript requests. JSON format is native to
 * Javascript, and can be directly eval()'ed with no further parsing
 * overhead
 *
 * All strings should be in ASCII or UTF-8 format!

Sehr gut.

Jetzt muss ich mich wohl noch mit Curl beschäftigen und das in die Extension einbinden. Richtig?

also brauche ich die php.curl.dll?

Wo kann ich die runterladen?

Schreib mal in Deine Signatur rein was Du so hast. Ohne Angabe der IPS-Version ist die Frage nicht wirklich zu beantworten.

So einfach scheint es ja nicht zu sein sich die php.curl.dll zu erzeugen. Puh… !

Das ist schon verdammt lange her, dass ich mich mit sowas mal beschäftigt habe.

Wenn ich das so richtig verstanden habe muss ich mir das ganze bei cURL - Download besorgen.

Einmal im Anhang…

Super super super.

So jetzt habe ich nur das Problem, wenn ich die Extension eintragen will, das IP-Symcon automatisch die php.ini überschreibt. Wie kann ich die php_curl.php dauerhaft verankern?

Edit: -> OK php.ini mit einem Schreibschutzversehen.

leider scheint die Extension nocht nicht zu funktionieren. Da das Script:

Fatal error: Call to undefined function curl_init()

diese Fehlermeldung auswirft.

Edit2:
Ich nehme alles zurück es läuft. Freu Danke noch einmal
