ich habe nach dem heutigen Update mehrere WARNINGs.
Sind diese bekannt oder kommen diese zu stande weil an anderer Stelle eine Falschangabe erfolgte?

Hallo,
das konnte ich mir schon denken. :)
Nachdem ich es aktivierte und nun laufen lies nach einem Restart, wurde die Konstellation bisher noch nicht geschaffen werden. Sobald ich die Stacktraceausgabe bekomme, poste ich diese hier.

Scheint von einer readingsGroup zu kommen.
Ich gehe davon aus das der Fehler kommt wenn die readingsGroup in der Browseranzeige läd.
Du musst nicht wissen wie es geht! Du musst nur wissen wo es steht, wie es geht.

Da liegst du bestimmt richtig. Ich habe Räume mit einigen Groups.
Gern würde ich ja diesen Fehler oder den Täter ermitteln, nur leider bin ich da etwas unwissend mich heranzutasten.
Es kann auch die Konstelation sein, wenn man FHEM neu startet und etwas nicht vorhanden ist.

Gibt es eine Möglichkeit dies einzugrenzen ohne das ich alle Groups nacheinander lösche und dann einzeln durchzutesten?

Zitatich greife mal das Thema noch einmal auf weil ich einen Stacktrace Output erhalten habe.
Du hast geschafft, dem readingsGroup ein undefiniertes Reading unterzujubeln, der hat das versucht Browsergerecht zu machen mit der Routine in FHEMWEB.pm, wo das Problem aufgefallen ist.

Ich bin unentschlossen, ob das:
- in FHEMWEB gefixt werden soll (unter dem Teppich kehren, fuer alle)
- in readingsGroup gefixt werden soll, da man hier dem Benutzer eine sinnvolle Meldung geben koennte.
- so wie es ist OK ist, weil es eh nur selten vorkommt, das kann man dann ueber Forum loesen, und man spart so den Extra-Code / Ballast.

ZitatGibt es eine Möglichkeit dies einzugrenzen ohne das ich alle Groups nacheinander lösche und dann einzeln durchzutesten?
Folgende Zeile in readingsGroup.pm, vor Zeile 1106, FW_htmlEscape Aufruf einbauen:
Code Auswählen
Log 1, "ERROR, undefined in $name, $device, $n" if(!defined($v));
und FHEM neu starten.

unter den Teppich kehren, halte ich für keine gute Strategie.

fhemweb zeigt keine Fehlfunktion (läuft stabil) und geht tolerant mit den fehlerhaft zugelieferten Inhalten um. Bonus: korrekte Ausgabe im Log um den Fehler einzugrenzen und damit Hilfe anzubieten um den Verursacher zu identifizieren. Alles richtig. Motorlampe leuchtet weil es im Motor ein Problem gibt.

Jetzt macht entweder Readingsgroup was falsch (erzeugt das undefinierte Reading trotz korrekter Bedienung) oder wird seinerseits mit fehlerhaftem Input versorgt. Ist doch jetzt ein Supportfall für Readingsgroup ... oder?
