@wolfgangfb einfach die Daten mitlesen
tail -f /var/log/wmbusmeters/wmbusmeters.log

Viel Glück

@matze-dev

da kommt nichts

[matze-dev]

@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?

Hier sieht es für mich so aus, als ob der USB Stick nicht erkannt wird. Muss man da evtl. einen Treiber installieren?

[matze-dev]

@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##

[WolfgangFB]

@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

[matze-dev]

@wolfgangfb ja, das hätte ich auch als nächstes angemerkt.

[WolfgangFB]

@matze-dev
Muss man da irgendeinen Treiber installieren?

[matze-dev]

@wolfgangfb nein, das macht der wmbusmeters. D.h. der ist der Treiber für das Device.

[matze-dev]

@matze-dev gibt's in dem Verzeichnis auch noch Dateien /var/log/wmbusmeters/meter_readings?

[WolfgangFB]

@matze-dev

Das Verzeichnis existiert ist aber leer (was ja auch logisch ist, wenn nichts gelesen werden kann).
