Monatsrückblick Oktober 2026 ist online!

Ich kann aktuell nur die FW der Sdongles anschauen, die ist: V200R025C00SPC110
Master Wechselrichter: SUN2000-10KTL-M1 SW Version: V100R001C00SPC178
Slave Wechselrichter: SUN2000-5K-MAP0: V200R024C00SPC110

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.

Ob das aktuell ist kann ich nicht sagen, sollte aber so sein, da SW Updates zur Inbetriebnahme nötig waren:
Hier die Intervalleinstellungen:

Hier die Einstellungen vom Adapter. Automatische Anpassung hatte auch keine Verbesserung zur Folge.

@Christian-Kohlöffel bitte sDongle FW updaten.
Deine Version ist veraltet.

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

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

@bolliy sagte:

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

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...)

[Christian Kohlöffel]

@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:

@Christian-Kohlöffel FirmWare der Batterieeinheiten prüfen. Die Updates kannst du auch über die App als Benutzer einspielen.

[Christian Kohlöffel]

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.

[rainereglinsky]

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.

[bolliy]

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.
