keine Verbindung zum MQTT

[fedex]

Hallo zusammen ich habe mir eine zweites System als backup angelegt.
Die konfigurationen sind bei beiden gleich.
nur bekomme ich bei der neuen installiertem System keine Verbindung zum MQTT Brocker hin.
im log bekomme ich diese Infos angezeigt

2022-05-06  06:54:17 ERROR    lib.metadata        module 'mqtt': Found invalid value '' for parameter 'broker_host' (type ip) in /etc/module.yaml, using default value '127.0.0.1' instead

2022-05-06 07:01:50 ERROR modules.mqtt Connection error: [Errno 111] Verbindungsaufbau abgelehnt

ich habe im Backend und auch in der modue.yaml selbst die ip eingetragen aber alles ohne erfolg


mit dem altem System klappt die verbindung sofort
das ist der Status vom MQTT broker

muss ich dem Linuxserver noch Zugriffsberechtigungen erteilen so das man sich mit dem Broker verbinden kann?
wenn ja wie mach ich das ?

[Onkelandy]

Ne, freigeben musst du nix. Kommen die 2 Logzeilen auch NACHDEM du die IP eingetragen hast? Weil dann hat da definitiv was nicht funktioniert. Poste doch mal die Sektion aus dem module.yaml..

[Msinn]

• Welche Version von SmartHomeNG setzt Du ein?
• Wie sieht denn Deine etc/module.yaml aus?
  
  Der Log Eintrag sagt klar, dass als IP Adresse ein Leer-String erkannt wurde (was ungültig ist) und deshalb der Stanardwert verwendet wird.

Wenn Du eine gültige IP Adresse einträgst, würde Dich das aber noch nicht zum Ziel bringen, da beide Installationen sich dann mit dem gleichen Client Namen am Broker anmelden, was dieser nicht mag. Das führt dazu, dass die Anmeldung des zweiten SmartHomeNG Servers dazu führt, dass der Broker die Verbindung mit dem ersten SmartHomeNG Server beendet. Worauf hin der erste SmartHomeNG Server ein Reconennt macht, was dazu führt, dass der Broker die Verbindung zum zweiten SmartHomeNG Server beendet, u.s.w.

Um aus dem Problem herauszukommen gibt es in der letzen Version von SmartHomeNG einen experimentellen (und noch nicht dokumentierten Parameter).

Aber beantworte erst mal die Fragen oben, denn die IP Verbindung zum Broker ist der erste Schritt und würde reichen, falls nicht beide Systeme gleichzeitig laufen sollen.

[fedex]

Das Bild ist aus dem Backend

das ist in der Module.yaml

mqtt:
module_name: mqtt
broker_host: 192.168.178.39
broker_port: 1883

ich verwende SmarthomeNG 1.9.2 master

die Systeme laufen beide unterschiedlichen raspberry's ich habe den Client so geändert das er zur neuen version verbinden soll sprich 192.168.178.39
das neue System läuft auch unter 192.168.178.39

[Msinn]

Wie ich oben schrieb, wird die ip Adresse aus der etc/module.yaml bei Dir nicht als solche erkannt, weshalb 127.0.0.1 verwendet wird und Da auf dem System kein Broker läuft, wird folgerichtig die Verbindung zu Port 1883, die das mqtt Modul aufbauen möchte, abgelehnt.

die Frage bleibt also: wieso erkennt SmartHomeNG bei Dir die in der Konfigurationsdatei eingetragene ip Adresse nicht. Mögliche Ansätze:
- Kommt der Konfigurationseintrag doppelt vor?
- Werden statt normaler Leerzeichen andere Zeichen verwendet?

[fedex]

das ist die ganze module.yaml

%YAML 1.1
---
# etc/module.yaml
# support for web server
http:
module_name: http
starturl: admin

# support for graphical admin interface
admin:
module_name: admin

websocket:
module_name: websocket
#port: 2424
#tls_port: 2425
#tls_key: myprivate.key
#tls_cert: myprivate.pem
#use_tls: true
#enable, if mqtt protocol is going to be used

#mqtt:
# module_name: mqtt
mqtt:
module_name: mqtt
broker_host: 192.168.178.39
broker_port: 1883

einen doppelt Eintrag sehe ich nicht
die Installation habe ich nach der Anleitung auf der Hompage gemacht
mit

sudo apt-get install mosquitto

ich bin davon ausgegangen das ich den Broker damit installiert habe
laut Status (oben) läuft doch der brocker auf diesem System ohne fehler

in Pi läuft unter der 192.168.178.2 (Mqtt funktioniert)
der andere unter der 192.168.178.39 (Mqtt läuft aber keien verbindung)

[fedex]

habe den eintrag nochmal neu in die module.yaml gemacht nun erhalte ich im log diese Fehler

mqtt:
module_name: mqtt
broker_host: 192.168.178.39
broker_port: 1883

2022-05-06 11:16:54 ERROR plugins.mqtt Module 'mqtt' not loaded. The plugin is not starting

2022-05-06 11:20:46 ERROR modules.mqtt Connection error: [Errno 111] Verbindungsaufbau abgelehnt

[Msinn]

Was sagt denn das Log des Brokers?
