@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).

[matze-dev]

@wolfgangfb hier gibt's einen Threat
https://github.com/weetmuts/wmbusmeters/issues/286
Ich würde mal in Richtung udev schauen, in meiner alten Version musste ich da noch was machen, die neue Software braucht das wohl nicht mehr.

[matze-dev]

@matze-dev Was sagt denn der Befehl:
wmbusmeters --debug auto:t1 MyTapWater auto 57813696 E4E7EAF6FD17EAFB9587BC2996783C63

[matze-dev]

@matze-dev Änderung, die vorher hier abgelegte Installationsanleitung ist heraus genommen, die komplette Doku findet sich weiter unten.

@wolfgangfb schau Dir mal meine hochgeladene Install-Doku an. Vielleicht kommst Du damit weiter.

[WolfgangFB]

@thomas-braun

In wmbusmeters.log steht nichts.
Ich frage mich allerdings, wie ich den "Other wmbusmeters" in den Griff bekommen kann. Da start ständig eine neue Instanz.

@wolfgangfb morgen müsste ich die komplette Doku fertig haben - dann kann man das komplette System von Scratch aufsetzen und hat dann alles beisammen. Ich stelle die Anleitung + Skripte dann hier ein.

[WolfgangFB]

@matze-dev

Super, ich hoffe, Du hast das dann auch mal mit einer echt blanken Raspberry Installation getestet.

[matze-dev]

@wolfgangfb in der Tat, das wird parallel mit einer neuen Karte aufgesetzt und gleich mitdokumentiert :-)

[matze-dev]

@matze-dev Kamstrup/Multical 21 realisiert mit Rasperry Pi, iM871A und iobroker zum Auslesen des Wasserzählers
Nun ist es soweit.
Anbei die Doku

Installationsbeschreibung-ioBroker-Rasp-PI+IMST871A.pdf

hier sind noch die erforderlichen Skripten -sind in der Doku beschrieben, wie man diese verwendet und einbaut.

extract_watermeters-values.js: das wird vom MQTT-Broker getriggert und liest die Werte aus, die im Datagramm stehen
extract_watermeters-values.js

calculate_average_new.js: das läuft einmal die Nacht und berechnet den Jahresgesamtverbrauch
calculate_average_new.js

hier sind noch 2 Hilfsscripten, wenn man die States neu anlegen oder löschen möchte - braucht man fürs erste nicht.
zum Löschen aller states: delete_states.js

zum Setzen aller states: create_states.js
