Alles klar, Danke. Dann werde ich das durchführen und berichten.

@Christian-Kohlöffel sagte:

Ich habe nur iobroker der noch ein anderes Gerät auf dem Modbus auswertet, sollte aber nicht auf die selbe IP zugreifen. Also nichts was ich extra so angegeben habe.

Deine Aussage verstehe ich nicht. Was greift bei dir per modbus wo zu?

Guten Morgen,
jetzt hat mein Installateur den Smartdongle aktualisiert, mein SW Version ist nun: V200R025C00SPC141

Das sollte nur heißen, dass ich noch ein weiteres Gerät habe das im Netzt per Modbus kommuniziert (meine WP),. Aber die hat ja eine andere IP, hierzu verwende ich den iobroker Modbus Adapter. Soweit ich weiß hab ich kein Gerät ausser den sun2000 adapter der auf den Sdongle zugreift.

Selbst mit dem neuen SW Update sieht es im Log immernoch ähnlich aus, siehe Anhang.

@Christian-Kohlöffel der zeitliche Ablauf und die Häufigkeit der Fehler (exception 6) deuten auf erhebliche Kommunikationsprobleme hin.

Überprüfe die Verkabelung der RS485-Kaskade

Die Verbindung zwischen Master (Pin 1/3 oder 2/4 je nach Modell) und Slave muss absolut stabil sein. Wenn hier Pakete verloren gehen, wartet der Dongle auf den Slave, was zu Timeouts führt.
Prüfe bitte, ob ein geschirmtes, verdrilltes Kabel (Cat6/Cat7) für die RS485-Verbindung genutzt wurde und der Abschlusswiderstand korrekt gesetzt ist (falls die Kabellänge lang ist). Der Dongle steckt zwingend im Master-Wechselrichter (Modbus-ID 1), der Slave hat meist die ID 2.

Könnte aber auch auf ein konkurrierenden modbus Zugriff hinweisen. Also bitte auch alles Abschalten was gleichzeitig auf den modbus zugreift! (evcc, HA, Apps, modbus Adapter, weitere sun2000 Instanzen...)

@bolliy

Hat eine Weile gedauert, ich habe alle COM Kabel geprüft, sind korrekt und gut verbunden und auch geschirmt verdrillt. Die Kabellänge ist ca. 1m. Der Master hat den Dongle drin stecken und der Dongle ist per Kabel LAN am 2m entfernten Router gut verbunden.

Alle andere Modbus Kommunikation sind ausgeschaltet. Alles neu gestartet und Einstellungen im Master Wechselrichter geprüft. Ich hab auch die Delay und Warte Zeiten im Adapter selbst ziemlich hoch gesetzt.

Nun gibt es eigentlich keine sporadischen Fehler mehr, sondern nur noch 2 relevante Fehler, die beide irgendwas mit der Batterie zu tun haben:

Ok, hab ich gerade gecheckt. Ich hab die aktuellste freigeben Version von September drauf V100R002C00SPC643 die neuere Version von Oktober wurde zurückgezogen laut ChatGPT ;-). Daran sollte es hoffentlich nicht liegen.

Hallo in die Runde,
ich habe leider bei meinem Rasberry pi 4 durch ein Update von Bookworm auf Trixie meinen gesamtes IOBroker verloren, da mein Backup auch nicht mehr funktionierte. Musste alles neu aufbauen, habe meine Huawei Sun2000 8KTL-M1 mit Luna2000-5kw-C0 und SDongleA-05 bisher ohne Probleme mit einem JS Script von Kachel verbunden.
Habe nun den schönen Adapter von bolliy installiert, IP Adresse, Modbus ID eingetragen und gestartet. Sofort alles grün (Host, Lebenszeichen o.k). War extra noch mal an der Anlage, habe die Modbus Freigabe unbegrenzt noch einmal kontrolliert - alles o.k.
Bekomme aber sofort die Fehlermeldung:

usw....
Wenn ich nun am Adapter eine Änderung vornehme (egal was) bekomme ich keine Verbindung mehr zum Gerät.
Habe nun schon Stunden mit der Recherche verbracht, bin aber zu keiner Lösung gekommen.
Was mache ich falsch?

rainereglinsky

rainereglinsky

Ist gelöst, hatte Netzwerkprobleme.

bolliy

@Christian-Kohlöffel Netzwerkbrobleme können natürlich auch zu Fehlermeldung führen. Der sDongle ist aus Stabilitätsgründen per LAN anstatt über WLAN mit dem Netzwerk zu verbinden. Das routen über mehrere Hobs kann problematisch sein.

Ich hab soeben die neueste Version von Dir aufgespielt. Leider sieht es dort weiterhin gleich aus, nur dass der Fehler mittlerweile immer beim selben Register ausgelöst wird (stable und neueste Version sind da identisch). Keine Ahnung ob das was bedeutet. Netzwerk o.ä. kann ich glaub ausschließen, hab ja nur 1m Kabel vom Wechselrichter zum Router und hier hab ich auch schon unterschiedliche versucht.

Was ist den im Register 3000? Kann das an der Kommunikation des Huawei Leistungsmesser mit der Batterie liegen oder ähnliches? Laut Chat GPT statischen Gerätedaten? (kann man die mal raus lassen?)

Ich hab gerade noch versucht die Baudrate von 9600 auf 19200 hochzustellen, wie es hier beschrieben ist:
https://github.com/evcc-io/evcc/discussions/22708

Da kommt wohl der Adapter nicht damit zurecht und kann keine Verbindung mehr herstellen.

bolliy

@Christian-Kohlöffel ich kann nicht erkennen, dass der Adapter überhaupt eine Verbindung zum Master aufbauen kann!
Der Aufruf Reg: 30000, Len: 71 ist zur Identifikation des Wechselrichets wichtig - kann also nicht weggelassen werden.
Ist die ip korrekt? Zuerst würde ich versuchen vom ioBroker Host den Wechselricher 192.168.178.181 anzupingen. Kannst auch den Adapter ping hierfür verwenden.

Danach mit telnet prüfen ob Port 502 offen ist:
telnet 192.168.178.181 502
Die Ausgabe sollte so aussehen:
Trying 192.168.178.181...
Connected to 192.168.178.181.
Escape character is '^]'.
Connection closed by foreign host.

Ich werde das Error handling und das Logging in der nächsten Version anpassen. Ich möchte einerseits das Log nicht "zuspammen" und auf der anderen Seite dem Anwender möglichst genaue Handlungsweise zur Fehlerbeseitigung geben. @christian-kohlöffel ich würde mich freuen wenn du die Anpassung in deiner Installationsumgebung testen würdest.
Warum das ganze?
Gerade der sDongle macht bei einigen Usern immer wieder Probleme. Entweder hat er alte und langsame Hardware oder eine nicht passende Firmware verpasst bekommen.

Test Adapter sun2000 Beta 2.7.5 – bessere Fehlerdiagnose bei Modbus-Problemen (vor allem sDongle)

Hallo,

die neue Beta bringt eine überarbeitete Fehlerbehandlung. Timeouts und Verbindungsprobleme, gerade beim sDongle, sollen sich damit leichter einordnen lassen.

Die Installation erfolgt über npm oder morgen über das Beta Repository.

Was ist neu?

Neue Warnungen: Ein neues Problem wird nur einmal gemeldet. Besteht es weiter, wiederholt sich die Warnung frühestens nach 30 Minuten. Wenn alles wieder läuft, gibt es eine Info-Meldung. Das Log wird nicht mehr zugespammt.
kumulierter Fehlerrate: Der Adapter bewertet die Modbus-Kommunikation jetzt in Zeitfenstern von ca. 2 Minuten. Eine Warnung kommt erst, wenn die Fehlerrate hintereinander über 2 % liegt, kurze Aussetzer bleiben also still.
Konkretere Hinweise im Log: Bei einer hohen Fehlerrate bekommst du zusätzlich Lösungsvorschläge zur Beseitigung.
info.JSONhealth mit currentStat: Zusätzlich zu den Summen seit Adapterstart (stat) steht dort jetzt der Zustand des letzten Fensters mit Anzahl der Abfragen, Fehlern, Timeouts sowie Fehler- und Timeout-Rate. Damit siehst du sofort, wie es gerade um die Verbindung steht.

Wiki

Die Seite „Fehlerprotokollierung und Fehlerbehebung (troubleshooting)" ist aktualisiert. Dort findest du alle Meldungen, die errno-Codes und Tipps zur Behebung:

https://github.com/bolliy/ioBroker.sun2000/wiki/Fehlerprotokollierung-und-Fehlerbehebung-(troubleshooting)

Testen

Postet bitte bei Problemen gern den Inhalt von sun2000.x.info.JSONhealth zusammen mit Angaben zu eurem Setup (sDongle ja/nein, Firmware, Abfrageintervall, Anzahl der WR).

Danke für euer Feedback!

Christian Kohlöffel

@bolliy
Erst mal Danke für die neue Version, hab sie natürlich gleich per npm installiert. Es sind nun deutlich weniger Fehlermeldungen im Log, und es sieht auch anders aus:

Zur Vollständigkeit ChatGPT hat mir noch geraten den Ping und die Verbindung über TCP Port 502 zum Zeitpunkt des ausfalls zu prüfen. Beide sind unauffällig:
Das Ergebnis ist ziemlich eindeutig: Der SDongle akzeptiert weiterhin TCP-Verbindungen auf Port 502. Alle vollständig gezeigten Tests waren erfolgreich, siehe sein Ergebnis dazu:

Zusammen mit deinen bisherigen Messungen ergibt sich folgendes Bild:
Prüfung Ergebnis
Ping zum SDongle Stabil
TCP-Port 502 Erreichbar
Modbus-Kommunikation Zeitweise gestört

@Christian-Kohlöffel sagte:

500

Bitte in modbus timing:
timeout: 10000
delay: 0
connectDelay: 5000

und dann noch mal die Fehler und sun2000.x.info.JSONhealth posten.

Klar, mach ich. Hab den Fehler gerade von der Fritz Box auf dem Port mit aufzeichnen lassen und über Wireshark gecheckt ob andere darauf zugreifen. Das können wir schon mal ausschließen.

Anbei die gewünscht Nachricht. Ich lasse das Log nun mal auf Silly mitlaufen und zeichne parallel mit der Fritzbox den Verkehr auf und lasse ChatGPT analysieren und hänge den Bericht hier an, er hatte da auch schon eine Meinung dazu, vielleicht hilfts ja. Die ganzen Protokolle will ich hier glaub nicht veröffentlichen.
