[Leonie]

Was steht in /etc/mosquitto/mosquitto.conf?

[Walter.O.]

@Leonie
nichts

[Walter.O.]

sorry falscher name.

Place your local configuration in /etc/mosquitto/conf.d/

A full description of the configuration file is at

/usr/share/doc/mosquitto/examples/mosquitto.conf

#pid_file /run/mosquitto/mosquitto.pid

persistence true
persistence_location /var/lib/mosquitto/

log_dest file /var/log/mosquitto/mosquitto.log

include_dir /etc/mosquitto/conf.d

[Leonie]

Na dann ist die Sache klar.

Erstelle die Datei /etc/mosquitto/conf.d/hannah.conf mit dem Inhalt:

echo listener 1883
allow_anonymous true

Danach den Service neustarten:
sudo systemctl restart mosquitto

möglicherweise musst du den Port anpassen wenn der Port 1883 bei dir bereits belegt ist.

[Walter.O.]

@Leonie
Port ist angepasst.
iob@iob:~$ sudo systemctl restart mosquitto

[Leonie]

Eigentlich steht in deinem Log was der Fehler ist und der ist in meinem Beitrag ;)

Das echo muss raus. die erste Teile lautet nur "listener 1883". Das echo ist mir beim Kopieren reingertuscht.

[Walter.O.]

@Leonie
Immer noch Fehlermeldungen
Was muss denn im mqtt adapter Client/Subscriber eingestellt werdenBenutzer Passwort.?
Sorry aber mit mosquitto hatte ich noch nie was zu tun.

[Leonie]

Was steht in /etc/mosquitto/conf.d/mosquitto.conf? evtl. brauchst du die hannah.conf gar nicht. In dem von mir bereitgestellten Beispiel ist der Broker anonym, man braucht also gar keine Anmeldedaten.

[Walter.O.]

Dort steht nichts drin

[Walter.O.]

Muss ich was in den .yaml Dateien ändern?

[Leonie]

Dein Log ist eigentlich eindeutig genug:

Nov 03 17:20:29 iob mosquitto[28225]: 1793722829: Error: Duplicate persistence_location value in configuration.
Nov 03 17:20:29 iob mosquitto[28225]: 1793722829: Error found at /etc/mosquitto/mosquitto.conf:26.

Du hast "persistence_location" mindestens zweimal in den Conifgs stehen.

[Walter.O.]

Ja habs gefunden da war noch eine zweite .conf die hab ich gelöscht, dann ging der restart sauber durch.
Der mqtt adapter bleibt bei "Verbunden mit Gerät oder Dienst" rot.

[Leonie]

du brauchst den mqtt-adapter gar nicht für Hannah

[Walter.O.]

@Leonie sagte:

du brauchst den mqtt-adapter gar nicht für Hannah

?

[Leonie]

Naja, Hannah spricht mit ioBroker nicht über MQTT. Und wenn du Mosqiutto als Broker nutzt, brauchst den Adapter in dem Kontext einfach nicht.

[Walter.O.]

@Leonie sagte:

Naja, Hannah spricht mit ioBroker nicht über MQTT. Und wenn du Mosqiutto als Broker nutzt, brauchst den Adapter in dem Kontext einfach nicht.

Woher weis denn hannah das sie jetzt mit mosquitto spricht und wo kann ich wie im mqtt die Datenpunkte sehen?

[Leonie]

in dem du das in den configs (core+Satelliten) einträgst.

Den MQTT-Adapter in ioBroker brauchst du nur, wenn du z. B. MQTT-Datenpunkte aus Mosquitto in ioBroker visualisieren oder verarbeiten willst. Für die reine Funktion von Hannah und den Satelliten ist der ioBroker-MQTT-Adapter komplett überflüssig. Wenn er auf Client steht und Mosquitto ohne Passwort läuft, müsste dort als Server IP 127.0.0.1 und Port 1883 eingetragen sein. Wenn du ihn nicht für andere Geräte brauchst: Einfach deaktivieren.
