Marstek Venus E Timeout

[Schlotze83]

Describe the bug

Ja Moin!

Ich nutze EVCC nun schon eine ganze Weile mit einer Heidelberg Energy Control Wallbox, die per USB an meinem Raspberry PI angeschlossen ist. Das funktioniert wunderbar und fehlerfrei.

Seit einem Monat bin ich im Besitz eines Marstek Venus-E Speichers mit 5,12 kWh, den ich in EVCC einbinden möchte, damit dieser als erstes geladen wird und danach das Auto.
Den Anschluß vom Speicher zum Raspi habe ich hinbekommen, ebenfalls mit einem USB Stecker und ich habe den Speicher auch konfiguriert bekommen. Per Config oder per UI ist es möglich, den Speicher hinzuzufügen.

Leider wird der Speicher nun nach kurzer Zeit nicht mehr gefunden und es gibt Timeout Fehlermeldungen.
Was muss / kann ich tun, damit das nicht mehr passiert?

evcc-20250728-091349-debug.log

Steps to reproduce

1. Speicher per USB an den RASPI anschließen
2. In der Config ist der Speicher laut Dokumentation eingefügt:

meters:
  - name: my_battery
    type: template
    template: marstek-venus
    usage: battery
    
    # RS485 via adapter (Modbus RTU)
    modbus: rs485serial
    id: 1
    device: /dev/ttyUSB1
    baudrate: 115200
    comset: "8N1"

3. Speicher wird erkannt und der Ladestand wird ebenfalls korrekt ausgelesen

[site  ] DEBUG 2025/07/28 09:05:35 battery 1 power: -517W
[site  ] DEBUG 2025/07/28 09:05:35 battery 1 soc: 77%
[site  ] DEBUG 2025/07/28 09:05:41 battery has priority at soc 77% (< 90%)

4. Nach Kurzer Zeit ist der Ladestand bei 0% und es werden Timeout-Fehler ausgegeben. Spannender Weise von der Wallbox

What type of operating system or environment does evcc run on?

Linux

External automation

• I have made sure that no external automation like HomeAssistant or Node-RED is active or accessing any of the mentioned devices when this issue occurs.

Nightly build

• I have verified that the issue is reproducible with the latest nightly build

Version

evcc version 0.205.0

Da past gar nichts:

Das passiert nur, wenn der marstek angeschlossen ist 😵

[Schlotze83]

Hat hier niemand eine solche Konstellation?

Per USB angeschlossene Wallbox und per USB angeschlossener Marstek Venus?

Bei der Wallbox habe ich im USB Adapter einen Widerstand eingebaut.
Das gleiche habe ich beim Speicher-USB-Adapter getan, allerdings nur einmal. Muss möglicherweise an beiden Seiten so ein Widerstand angebracht werden?

[oldgitdaddy]

Habe ein ähnliches setup, Nutze aber für die Verbindung zum Marstek einen Wifi-Modbus dongle.

Was meinst Du genau mit per USB angeschlossen? SInd beide Geräte an einem Kabel? Oder jeweils an unterschiedlichen USB-Ports?

[Schlotze83]

habe 2 unterschiedliche USB Adapter - ttyUSB0 ist die Wallbox, ttyUSB1 der Speicher. 2 Adern aus den Netzwerkabeln sind mit diesen Adaptern verbunden.

[oldgitdaddy]

Für die Batterie müssen doch insgesamt 4 Kabel verbunden sein. Hast Du das geprüft?

Wahrscheinlich sind es doch nur 2. Weil Du keine Stromversorgung brauchst. Aber bist Du Dir sicher, die richtigen Kabel miteinander verbunden zu haben? Gibt ja bei den unterschiedlichen Versionen der Batterie unterschiedliche Belegungen.

[Schlotze83]

Es funktioniert ja für einen Moment... Lass es ein paar Minuten sein.
Mit den Adaptern kann ich nur A und B anschließen.

[oldgitdaddy]

Wenn das ganze mit einem Raspberry Pi läuft, kann es gut sein, dass die Stromversorgung vom Pi nicht stabil ist. Das ist mindestens ein Problem auf dem Raspi 4. Nutzt Du einen Raspi 4?

[Schlotze83]

Ja, das ist ein 4er. Habe das original Netzteil... Wie umgeht man das?

[oldgitdaddy]

Funktionieren denn beide Geräte separat, wenn der andere USB Dongle jeweils entfernt wurde?

[Schlotze83]

Könnte ich auch besorgen... Hatte den USB Adapter da... Ich versuche es mal, Steckdosen sind rar im HA Raum 😵

[Schlotze83]

Ob das mit dem Speicher funktioniert, kann ich nicht sagen, da die wallbox immer erreichbar sein muß, damit evcc überhaupt startet

[oldgitdaddy]

Also wenn Du die Batterie als Sensoren in HA verfügbar machen möchtest, ohne auf EVCC angewiesen zu sein, kannst Du auch auf Basis dieser YAML, eine eigene Batterie Integration via ModBus in HA bauen: https://github.com/Superduper1969/MarstekVenus-ElfinEW11

Inspiriert und beschrieben ist es auch hier: https://gathering.tweakers.net/forum/list_messages/2282240/0 (google translate hilft beim Niederländischen)

Herzlichen Dank für die Hinweise! Ich werde das mit HA einmal probieren, hoffentlich läuft das mit der Docker-Version 🤗😘
