Hab ich auch gehört, dass der lan Stick das kann. Wäre die nächste Variante gewesen, wenn das mit der rs485 nicht geklappt hätte.

[spicer]

Habe nun ein anderes Problem.
Nach 1-2h kommt ein "Socket closed with error". Dann geht nichts mehr.

Wenn ich den modbus Adapter neu starte, läuft's wieder.

Ergänzend fällt mir auf, dass der immer mit einem "Socket closed with error" abschliesst.

Schon wieder. Adapter lief ca 3-4h.
Man siehe den Log ab 2026-02-06 03:59:39.013.
Da stirbt die Übertragung langsam bis ab 2026-02-06 03:59:56.664 nix mehr kommt.
Wie bereits gesagt, funktioniert alles wieder nach einem Adapter neustart.

@spicer sagte in Sofar Solar HYD10 KTL Wechselrichter an modbus Adapter:

Da stirbt die Übertragung langsam bis ab 2026-02-06 03:59:56.664 nix mehr kommt.

was startet bei dir um 04:00?

Laut Log nichts zur Fraglichen Zeit.
Die gelesenen Register nehmen schon vor sofarcloud und weathersense ab.

Aber ist schon auffällig, dass es immer um die gleiche Zeit passiert.
Kann ich iwie den Adapter immer um 4:01 neu starten?

[spicer]

Jetzt hat es um 2026-02-06 16:04:24.546 angefangen. Nach nur ein paar Minuten!

Mir gefällt das "Socket closed with error" jedesmal nicht.
Das könnte doch irgend etwas füllen bis zum Crash.
Sauber ist das auf jeden Fall nicht.

kaufe dir einfach dieses Teil und du hast Ruhe, 55 Euro kostet weniger als die Nerven die du lassen musst. Vor allem hast du es gleich auch noch in der App

Beim Waveshare musste ich auf "Transparent" (anstelle von "modbus TCP <=> modbus RTU") stellen.
In der config seht ihr auch, dass LXCs und der Waveshare nicht im gleichen Netzwerk sind. WAN von 192.168.88.0 (MikroTik Router) hängt am Netz 192.168.1.0 (Fritzbox). Da hab ich eine Route definiert, damit man vom einen ins andere Netz zugreifen kann.
Die IPs, Ports, Usernames und Passwörter müsst ihr natürlich auf eure Gegebenheiten anpassen.

In der /etc/systemd/system/modbus-mqtt.service

[Unit]
Description=Modbus RTU over TCP to MQTT Gateway
After=network-online.target
Wants=network-online.target

[Service]
Type=simple
User=root
WorkingDirectory=/opt/modbus-mqtt
ExecStart=/usr/bin/env python3 /opt/modbus-mqtt/modbus_tcp_rtu.py
Restart=always
RestartSec=5
Environment=PYTHONUNBUFFERED=1

[Install]
WantedBy=multi-user.target

Wenn alles fertig ist, eingeben:

sudo systemctl daemon-reload
sudo systemctl enable modbus-mqtt.service
sudo systemctl start modbus-mqtt.service

Die Daten werden nun per MQTT an den ioBroker gesendet.
Der Datenpunkt sieht dann etwa so aus:

mqtt.0.modbus.inverter.register.{Registeradresse}

das ist, warum mir ein solcher Konverter zu komplex ist.
Dann noch bei gleichem Hersteller unterschiedliche Einstellungen braucht....

davon war bisher keine Rede

Das hat ja auch nichts mit den "Hängern" zutun ;)
Der Adapter läuft ja ein paar Stunden gut.

sicher?

der socket wird angemeckert!

Ja eben. Das hab ich weiter oben ja schon festgehalten.
Da konnte mir niemand einen Rat geben.
Darum hab ich dann ein eigenes Script erstellt ;)
Und das läuft seit der Erstellung stabil.

dem HYD in 10Sek auszulesen ist keine gute Idee
ich habe auch hin und wieder Fehler, aber er liest bei mir danach einfach weiter aus.

weiterhin verwendest du einen Waveshare, was ich nicht ganz verstehe, warum du da immer noch Port 8899 drin hast im Modbus Adapter vom IOBroker
ich musste den Port vom Waveshare im Modbus vom IOB sowie die IP vom Waveshare da eintragen und im Waveshare den Port vom WR
so wundert mich das.

ich nutze einen Waveshare 4CH und das läuft echt sauber und problemlos
1x Sofar HYD
1x Sofar KTLX
1x Growatt
gleichzeitig mit vers. Auslesezeiten und mit 3 Modbus Adaptern
vorher einen einfachen Waveshare nur für den HYD, lief auch stabil

Ich habe nicht den gleichen Waveshare (siehe oben).
Hatte auf 20s eingestellt. Trotzdem standen die DPs plötzlich still.
Mit meinem Script läuft es nun stabil. Habe da sogar 13s Intervall.

Falls noch jemand seinen Sofar Modbus nicht zum laufen kriegt:

Nichts gegen den Adapter. Der ist genial geschrieben. Aber alle Konstellationen kann man nicht abfangen mit einem allgemeinen Programm.
Ist nur zum Empfang. Kein senden von Commands.
