So, ich denke wmbusmeters läuft jetzt (sieht zumindest grün aus).

mosquitto scheint prinzipiell auch zu laufen:

pi@raspberrypi4:/var/log/wmbusmeters/meter_readings $ mosquitto
1626210924: mosquitto version 1.5.7 starting
1626210924: Using default config.
1626210924: Opening ipv4 listen socket on port 1883.
1626210924: Error: Address already in use

Aber was ist mit dem Error "Address already in use"? gemeint?

Im IO-Broker bleibt der mqtt Adapter rot (im Logfile steht nichts)

[matze-dev]

@wolfgangfb: das ist korrekt - die "Fehlermeldung" kommt bei mir auch. Ist aber das "falsche" Kommando, weil der wmbusmeters-Treiber laut Konfig-Zeile das Programm /usr/local/bin/mosquitto_pub aufruft - wenn das bei Dir auch so in der /etc/wmbusmeters.conf steht.
Du siehst den Erfolg nur in den Logfiles, wenn da was steht, passt es!

[WolfgangFB]

@matze-dev

Hallo

In dem Logfile steht leider nichts gutes:

@wolfgangfb said in Adapter WM-Bus / Kampstrup Multical 21:

Warning! Desired link modes none cannot be set for device /dev/ttyUSB0:im871a[00100776]

Dieses Warning ist komisch!? Ich habe bei mir die Datagramme im T1-Mode.
Dann müsste in der /etc/wmbusmeters.conf
die Zeile so stehen:
device=/dev/ttyUSB0:im871a:t1
ggfs. kann man hinten das :t1 weglassen - müsste man versuchen.

Dann ist noch wichtig, den AES-Key hier zu hinterlegen:
/etc/wmbusmeters.d/MyTapWater
key=xxxxxxxxxxxxxxxxxxx

Viel Glück

[WolfgangFB]

@matze-dev
Die Warning ist jetzt zumindest weg, mal sehn ob innerhalb der nächsten Stunde was ankommt.

@wolfgangfb ja, da scheint nichts anzukommen. Ausserdem macht er ein Reset. Das ist ungewöhnlich.
Was sagt denn
journalctl -f
dmesg?

@wolfgangfb würde vorschlagen, den Stick einmal ziehen und dann wieder stecken. Dabei dmesg laufen lassen. Was erzeugt er für Meldungen?

@wolfgangfb hallo, gibt's die Datei /etc/wmbusmeters.d/MyTapWater, wie oben beschrieben?

[WolfgangFB]

@matze-dev

Ja, habe ich ja mit

 more /etc/wmbusmeters.d/MyTapWater

angezeigt, dann muss es sie ja auch geben.
Darin sehe ich aber nichts was mir die Meldung im wmbusmeters.log (DeviceNotFound) erklären würde.

Wie sieht den Dein wmbusmeters.log aus?

[matze-dev]

@wolfgangfb sind da auch der Key drin und die Zähler ID?

[matze-dev]

@matze-dev
Das muss in der MyTapWater stehen

name=MyTapWater
type=multical21
id=##der Name/ID des Zaehlers ##
key=##hier den Key eintragen - kommt aus der zugeschickten XML-Datei des Wasserversorgers##

@matze-dev

Ja, habe ich doch in meinem Beitrag alles gequoted (incl. Key weil ich nicht denke, dass damit irgend jemand etwas anfangen kann). Fünfter Codeblock.

[matze-dev]

@wolfgangfb ok, habe es gesehen.

[WolfgangFB]

@matze-dev

Ich denke das Entscheidende ist die Zeile

[2021-07-17_16:31:43] [ALARM SpecifiedDeviceNotFound] the device /dev/ttyUSB0:im871a:t1 is not working

aus

 more /var/log/wmbusmeters/wmbusmeters.log

Codeblock 7
