Jahresrückblick 2025 – unser neuer Blogbeitrag ist online! ✨

[Fox223]

Hallo,
versuche seit einigen Tagen unsere Wallbox in EVCC zu integrieren. Die Wallbox ist per RJ485 angeschlossen. Leider laufe ich in EVCC immer in einen Timeout.

Jetzt habe ich eben mal versucht die Wallbox per ioBroker anzusprechen. Bin mir zwar nicht 100% sicher, aber für mich sieht es so aus, also wenn die Wallbox verbunden wäre- Trotzdem bekomme ich keine Daten.

Habt ihr einen Rat für mich?

@fox223 sagte in Wallbox per Modbus integrieren:

Invalid holdingRegisters address: -18699

zeig mal die Grundeinstellungen
und die Registerbeschreibung des Gerätes

wa hast du sonst noch an Registern defi iert.
Laut log sind das mehr als 2

[Fox223]

@homoran

Hey, die Register habe ich hier her https://github.com/Eisbaeeer/sungrow/blob/main/AC011E01_Input-Register.tsv

Meinst du das hier mit Grundeinstellungen?

[Homoran]

@fox223 sagte in Wallbox per Modbus integrieren:

Grundeinstellungen

ja!

@fox223 sagte in Wallbox per Modbus integrieren:

die Register habe ich hier her

dem Link-URL nach geht's da um INPUT register, dein Modbus meckert aber HOLDING Register an!

Da du die Titelzeilen immer abschneidest weiss ich nicht was du wo machst.

[Mabbi]

@fox223

Hi,

ich habe eine em2go, die benötigt auf jeden Fall HOLDING-Register. Kann das evtl. Dein Problem sein ?
Geräte ID 248, wo hast Du den Wert her ?

Wenn Du kannst, dann besorg dir mal die TCP-Modbus config vom Hersteller mit den Registern.

[Fox223]

@homoran

sorry

@Mabbi Die 248 habe ich aus dem evcc Forum. Da laufen einige Wallboxen ohne Probleme.

Der Anschluss läuft über RJ485

[Homoran]

@fox223 sagte in Wallbox per Modbus integrieren:

Da laufen einige Wallboxen ohne Probleme.

haben alle Boxen gleiche Register?
und welche Box hast du?

und was ist mit
@homoran sagte in Wallbox per Modbus integrieren:

??
Da werdrn Holdingregister angemeckert!
hast du da auch noch was drin?

Warum hast du "alias verwenden" angehakt? mach das mal weg

[Fox223]

@homoran
Ich habe die Sungrow ac011e-01
Finde leider von Sungrow selber keine Infos zu den Registern und der Adresse.

Habe sonst keine Register mehr dring:

@fox223 sagte in Wallbox per Modbus integrieren:

dann wundern mich die Meldungen

dass die Werte negativ sind wird an dem Haken hei Alias liegen

[Mabbi]

@Fox223

Grundsätzlich, das ist aber meine persönliche und eventuell technisch nicht ganz durchdachte Antwort, würde ich erstmal den TCP MODBUS zum Laufen bekommen, dann per Script Befehle in die richtigen Register schreiben. Wenn Du dann Deine WB unter Kontrolle hast, Laden und Ladestrom z.B., dann kannst Du Dich immer noch mit EVCC beschäftigen.

Ich habe auf EVCC verzichtet und steuere PV-Überschuss laden mit einem simplen Script.
Das muss aber jeder für sich entscheiden, EVCC ist ein mächtiges und soweit ich höre auch gutes tool. Das kann aber nur funktionieren, wenn du den TCP-Modbus wirklich fehlerfrei am Laufen hast. Macht dann auch das Fehlersuchen/Debuggen einfacher, wenn alles was passiert aus Deinem Script kommt.

Hier mal mein EV-Steuerscript (ist simpel, ich bin kein Java Profi und man kann das sicher besser machen, aber es funktioniert und ich habe es selber gebastelt):

var Strombegrenzung_Wallbox_EV_laden, Aktuelle_Ladeleistung, Lade_Restart_Delay;
// Strombegrenzung MINIMUM 60 Ampere (Hersteller)
Strombegrenzung_Wallbox_EV_laden = 60;
Aktuelle_Ladeleistung = 60;
// Pause nach Ladeende bis Neustart in Millisekunden
Lade_Restart_Delay = 1 * 60000;
schedule("* * * * * *", async () => {
  // 1 Sekunden Timer
  // Wallbox Ladestrom EV
  setState('0_userdata.0.Datenpunkte.EV_Wallbox.EV-Ladestrom' /* EV-Ladestrom */, (String(Math.round(parseFloat(getState('modbus.1.holdingRegisters.16_Wirkleistung_L1').val) + parseFloat(getState('modbus.1.holdingRegisters.20_Wirkleistung_L2').val) + parseFloat(getState('modbus.1.holdingRegisters.24_Wirkleistung_L3').val)))));
  // Wallbox Ladekabel in Auto eingesteckt

Die hier in modbus.1.holdingRegisters. angegebenen Register sind spezifisch für meine em2go WB und NICHT generisch zu verwenden!

Für die Profis unter Euch, ein sehr altes script, wo ich noch dachte, es ist eine gute Lösung, alle eigenen Datenpunkte als String anzulegen. Man lernt halt nie aus :)
