Jahresrückblick 2025 – unser neuer Blogbeitrag ist online! ✨

[spicer]

Welcher Parameter ist das Total für Battery Power und SOC?
Ich sehe in der xls Tabelle nur Parameter für Bat1, Bat2 usw.
Ich habe 4 Batterien dran.

[RISSN]

Warum nimmst du nicht einen Stick? Die Sticks für den Sofar mit LAN können auch Modbus, nutze ich so schon ein Jahr, geht super und die Daten gehen auch gleich in die App

[spicer]

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.

Laut Log nichts zur Fraglichen Zeit.

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}

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

Beim Waveshare musste ich auf "Transparent" (anstelle von "modbus TCP <=> modbus RTU") stellen.

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

dass LXCs und der Waveshare nicht im gleichen Netzwerk sind.

davon war bisher keine Rede

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

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.
