Sungrow WR SGH10RT erfolgreich mit MODBUS eingebunden

@aleks-83 sagte in Sungrow WR SGH10RT erfolgreich mit MODBUS eingebunden:

Das habe ich so hier aus dem Forum übernommen.

Bei der Einstellung der Register besser die offizielle Dokumentation des Herstellers beachten.
Einträge im Forum können falsch oder veraltet sein.

[Schneider]

Hi, ich versuche mit obiger Anleitung einen SH20T anzubinden.
Bin MODBUS Neuling - bitte nicht steinigen

Ich bekomme die Register nicht reinkopiert. Was mach ich da falsch?

[gmt94]

@schneider

Die ganzen Einsen sind falsch. Also zwischen Adress und Name, die müssen raus.

[berlinerbolle]

@schneider
@gmt94

Falsch sind die Einsen nicht per se - ich würde empfehlen, die drin zu lassen. Dafür muss aber im Modbus Adapter in den Einstellungen "Multiple Device IDs" angehakt sein, sonst klappt es nicht.

Vorteil dabei: man kann die einzelnen Batteriewerte per Modbus auslesen, die Batterie hat eine eigene Modbus Adresse.

Siehe hier.

@berlinerbolle
Zumindest ist offensichtlich, dass die Tabelle derzeit nicht zu den Überschriften passt. Ob es eine Einstellung gibt, die der Tabelle eine weitere Spalte hinzufügt, weiß ich nicht. Aber derzeit passen die Einsen jedenfalls nicht rein. Die „Unit“-Werte der Einfügungen werden offensichtlich, wie auch die Fehlermeldung sagt in der Spalte „type“ eingefügt - und entsprechen deshalb nicht den hinterlegten, erlaubten, Werten.
Die Einsen sind hier und jetzt jedenfalls zu viel.

@gombersiob

Vollkommen richtig, so wie es im Screenshot ist, kann es nicht funktionieren - egal ob die Option "Multiple Device IDs" angehakt ist oder nicht. Mit der angehakten Option kommt eine zusätzliche Spalte "deviceId" dazu, die natürlich in der ersten Zeile entsprechend dabei sein muss.

Deshalb mein Verweis auf das github Repo, da passt es.

[Schneider]

Cool, hat geklappt. Danke für die Hilfe.

Jetzt habe ich die Objekte drin - allerdings stehen alle auf "0":

nicht wirklich.
Da steht bestimmt was im log.

Das NaN statt Registernummer spricht Bände

Wo befindest du dich da?

[Schneider]

Protokolle:

Objekte:

[Homoran]

@schneider ... und die Konfiguration?

[Schneider]

Diskrete Eingänge / Ausgänge habe ich nichts eingetragen. Ebenso ins Holding-Register.

[ubecker]

@schneider nimm mal in der Config Aliasse benutzen raus. Ich erinnere mich das hatte ich auch mal so

[Homoran]

@schneider bitte Logstufe auf debug umstellen.
Hak mal "aliases benutzen" ab

[Schneider]

Jetzt verbindet sich der Adapter nicht mehr

[Homoran]

log bitte als Text in code-tags posten und auf debug umstellen

EDIT:
Wo komnt jetzt due Geräte ID 200 und doppelt so hohe Register her?

[berlinerbolle]

@schneider

Und nimm zur Sicherheit erstmal die Zeilen mit DeviceID 200 (das ist die für den Akku mit den entsprechenden Modbus Registern) ganz raus. Die DeviceID des Akkus MUSS nicht 200 sein (kann man zum Beispiel über das WinetS nachschauen), falls du überhaupt einen hast? Bin gerade am Handy und kann nicht zu deinem ersten Post schauen, welchen Wechselrichter und/oder Akku du hast.

Ältere Firmware Versionen führen den Akku auch gar nicht separat auf, das könnte auch eine Ursache sein auch falls du einen Akku hast.

[gmt94]

@schneider

Hast du im Winet dongel überhaupt modbus aktiviert?

[GombersIOB]

@schneider
Diese „Not-a-Number (NaN)“ beziehen sich auf die Registernummern. Da steht in der Spalte sicher noch ein Leerzeichen dabei. Etwa „4999 „ statt „4999“.

Das Thema hatten wir gerade erst
https://forum.iobroker.net/post/1221502

Deswegen warte ich auch noch auf das debug-log von @schneider
