@homoran nochmal es geht NICHT um mbus sondern um MODBUS

Außerdem ist in deinem log kein rinziger debug Eintrag.
Hast du die modbus Instanz wirklich auf Logstufe debug gestellt?
oder nur den Filter im Protokoll?

So ein Quatsch.
Du schreibt: Es kommen Errors.
Zeigst dann mbus.
Und schreibst mbus läuft.

Und ich werde gar nichts nachlesen.

Du hast Probleme mit modbus. Dann zeigt dies auch.
Und nicht mbus !

@homoran sagte in Probleme mit modbus Stromzähler, keine Werte:

schön, dass du den entziffern kannst

auf einem 27" geht es.

[obstbauer]

ich sollte den debug log zeigen, das habe ich getan
dort sind nur mbus Fehler zu sehen oder ich schaue an der falschen Stelle

ich kann sonst keinen log für modbus finden der mir Fehler anzeigt

Wenn du hier nur Anfänger rund machen willst, klasse viel Spaß dabei!
Entweder willst du helfen oder lass es bleiben

dann bekommen wir das schon hin

Das hat @homoran geschrieben.
Schalte modbus auf debug und zeige das log in code-tag.

So kann man nicht helfen.

@obstbauer

Das ist wieder mbus.1

Ich denke modbus klappt nicht

[Homoran]

@obstbauer Danke!
aber nur mbus Meldungen

hast du vielleicht auf mbus gefiltert?

wurde die modbus Instanz neu gestartet?
das muss im log zu sehen sein.

[obstbauer]

@bahnuhr ja sorry ich arbeite daran
weiß gerade nicht wie ich modbus auf debug schalte, das ist das was mir bei Protokolle angezeigt wird, da taucht nur mbus auf, entschuldigung für die Verwirrung

hab dir doch was zum lesen verlinkt
https://forum.iobroker.net/topic/51555/hinweise-für-gute-forenbeiträge/1

[bahnuhr]

@obstbauer

Dort auf debug stellen.

Und dann instanz neu starten.
Und dann log hier als code-tag posten.

[obstbauer]

so ich denke jetzt habe ichs, sorry....

Also scheint es doch zu klappen.

Also nochmal die Frage:
Was klappt jetzt nicht bei modbus ?
