ModbusAttr Device (Marstek Venus E) reduziert FHEM Performance

Dracolein · 06 April 2026, 18:13:42

Hallo zusammen,

ich habe mich in den letzten Tagen in die Modbus Thematik reingenerdet. Mein Ziel war es, den neuen Marstek Venus E 3.0 für FHEM lesbar und steuerbar zu machen. Technisch habe ich es inzwischen störungsfrei am laufen. Während 3 Hilfs-Devices nur zur aktiven Steuerung dienen und hier ignoriert werden können, liegt mein Fokus auf dem Main-Device vom Typ ModbusAttr.

Der Grund für diesen Thread bzw. mein "Problem": Meine FHEM Instanz ist nun spürbar deutlich weniger performant, als ich es seit Jahren gewöhnt bin. Einfachste Steuerbefehle (Licht an) haben plötzlich Delays von 1-3 Sekunden, was ich so nicht hinnehmen möchte. Im Folgenden gebe ich das Device als Raw-Code hier mit und hoffe auf Eure Expertise speziell mit Fokus, ob ich irgendwelche Attribute doof / falsch / Suboptimal / whatever definiert habe und dadurch Performance leidet?

Was ich schon getan habe:
- Polling auf 30 Sekunden raufgesetzt
- Register rausgelöscht, die ich nicht unbedingt benötige
- polldelay für diverse Register definiert

Sonstiges:
- FHEM (auf Raspberry Pi) via LAN im Netzwerk
- Batteriespeicher via LAN im Netzwerk
- feste IP-Adressen
- Schnittstelle am Batteriespeicher: Modbus-TCP
- Geräte-Pings im niedrigsten ms-Bereich (also eig. top)

Ich frage mehrere Register gleichzeitig in einem Block ab, die nicht zusammenhängen und Abfragelücken haben. Kann das ein Problem sein?

Hi Dracolein,

hab grad Dein post gefunden, da ich auch seit ein paar Tagen am gleichen Thema bastele. Ich kann Deinen Ansatz super gebrauchen

. Ich hab Deine Version mal 1:1 auf einem Testsystem installiert (auf einem RasPi 4) und kann keinen nennenswerten Performancenachteil spüren bzw messen. Bei mir läuft es auch auf meinem Realen System IntelCeleron unter pve im container, 2 Kerne, 1GB Ram top.

Gruß Mirko

Dracolein · 11 April 2026, 06:24:23

Habe folgende Attribute editiert, seither sind die "Lags" (blocking?) weitgehend verschwunden

Also ich hatte dein Dev jetzt durchgehend am laufen, keine Probleme.

Bei mir: Fhem Server per LAN im Netz, Speicher per RS485->Wlan da Router direkt daneben und Ports alle belegt.

Dracolein · 11 April 2026, 08:00:37

Ich teile informativ, wie ich den Marstek aus FHEM heraus steuere:

1.) scheint es ein Keepalive-Signal zu benötigen, um die Karre im Eingriffsmodus zu halten, wenn man längere Zeit manuell steuern will, dazu gibts pauschal ein at-Device:

Code Auswählen

defmod at_MarstekKeepAlive at +*00:00:25 {\
  if (ReadingsVal("MarstekVenus01","ForceMode","Aus") ne "Aus") {\
    fhem("set MarstekVenus01 ControlMode 21930")\
  }\
}
attr at_MarstekKeepAlive comment Alle 25 Sekunden wird geprüft ob der Marstek gerade per ForceMode gesteuert wird. \
Nur wenn ja, wird ControlMode erneuert. Das verhindert dass der Marstek die externe Steuerung nach ~15 Sekunden selbst abschaltet \
ohne dass im Normalbetrieb unnötig Register geschrieben werden.
attr at_MarstekKeepAlive group Marstek
attr at_MarstekKeepAlive room Befehle,Photovoltaik

Ein Dummy-Device dient zum Erzeugen von steuerbaren Readings:

Code Auswählen

defmod dummy_MarstekBefehl dummy
attr dummy_MarstekBefehl comment Erst die Leistung setzen, dann den Befehl, Beispiel:\
set dummy_MarstekBefehlLeistung 300\
set dummy_MarstekBefehl Befehl Laden\
\
Befehle:\
Laden    - Lädt mit eingestellter Leistung (ForceMode)\
Entladen - Entlädt mit eingestellter Leistung (ForceMode)\
Standby  - Manueller Modus ohne Zeitfenster, weder laden noch entladen\
Stop     - Beendet externe Steuerung, Marstek kehrt in Eigenverbrauch zurück
attr dummy_MarstekBefehl group Marstek
attr dummy_MarstekBefehl readingList Befehl Leistung
attr dummy_MarstekBefehl room Photovoltaik
attr dummy_MarstekBefehl setList Befehl:Laden,Entladen,Standby,Stop Leistung:50,100,200,300,500,800,1000,1500,2000,2500
attr dummy_MarstekBefehl stateFormat Befehl

Das DOIF-Device übernimmt Steuerbefehle und führt sie aus:

Code Auswählen

defmod MarstekDOIF DOIF ([dummy_MarstekBefehl:Befehl] eq "Laden")\
  (set MarstekVenus01 ControlMode 21930)\
  (set MarstekVenus01 SetChargePower [MarstekBefehl:Leistung])\
  (set MarstekVenus01 ForceMode Laden)\
DOELSEIF ([dummy_MarstekBefehl:Befehl] eq "Entladen")\
  (set MarstekVenus01 ControlMode 21930)\
  (set MarstekVenus01 SetDischargePower [MarstekBefehl:Leistung])\
  (set MarstekVenus01 ForceMode Entladen)\
DOELSEIF ([dummy_MarstekBefehl:Befehl] eq "Standby")\
  (set MarstekVenus01 ControlMode 21930)\
  (set MarstekVenus01 ForceMode Aus)\
  (set MarstekVenus01 Betriebsmodus Manuell)\
DOELSE\
  (set MarstekVenus01 ForceMode Aus)\
  (set MarstekVenus01 Betriebsmodus Eigenverbrauch)\
  (set MarstekVenus01 ControlMode 21947)
attr MarstekDOIF do always
attr MarstekDOIF group Marstek
attr MarstekDOIF room Photovoltaik
attr MarstekDOIF wait 0,2,1:0,2,1:0,1,1:0,1,1

Somit braucht es dann nur noch beispielsweise:

Zitatset dummy_MarstekBefehlLeistung 375

gefolgt von

Zitatset dummy_MarstekBefehl Befehl Laden

und die Batterie versetzt sich in den Modus "Manuell" und beginnt mit 375 Watt zu laden, bis ein anderer Befehl gesendet wird. Wie oben im Device als Kommentar hinterlegt:
Befehle:
Laden - Lädt mit eingestellter Leistung (ForceMode)
Entladen - Entlädt mit eingestellter Leistung (ForceMode)
Standby - Manueller Modus ohne Zeitfenster, weder laden noch entladen
Stop - Beendet externe Steuerung, Marstek kehrt in Eigenverbrauch zurüc

Nachtrag: Anbei zwei Codeschnipsel zur Verwendung als userReadings, um die tägliche Batterie-Ladung und -Entladung mitzuloggen (um sie abends vor Tagesablauf anderweitig wegspeichern zu können)

  my $now     = time();;
  my $age     = $now - $last_ts;;
  return undef if $age <= 0 || $age > 60;;
  my $prev    = ReadingsNum("MarstekVenus01","BattChargeDay_kWh",0);;
  return sprintf("%.2f", $prev + ($power * $age / 3600000));;
},
BattDischargeDay_kWh {
  my $power = ReadingsNum("MarstekVenus01","BattPower",0);;
  return undef if $power >= 0;;

Hallo Dracolein,

vielen Dank fürs posten deiner Lösung. Ich habe mit noch schnell einen Marstek Venus E 3.0 gesichert und deine Lösung soweit wie möglich nachvollzogen doch bei diesen beiden Codes steige ich leider nicht mehr durch:

Zitat

Die Zeilen mit \ (und evtl ;; ) verwendet man, wenn man fhem.cfg aendert, oder die Daten in Raw Definition (unten in der ... Menue) eingibt.
Ansonsten bitte alle \ entfernen, und statt ;; nur ; schreiben (Letzteres ist in diesem Beispiel nicht vorhanden).

Ich bin noch in der Testphase aber soweit scheint es zu laufen!

Ich habe deine Lösung bis auf den Dummy-Device zur Steuerung (brauche ich für meine Lösung nicht) und die zwei userReadings zum loggen (muss ich noch machen, ist aber nicht so straight forward) nachvollzogen und mit meinen eigenen DOIFs zur Steuerung über meine in FHEM integrierte SolarEdge Anlage ergänzt:
