@mguenther
Der Auszug ist unauffällig.

[mguenther]

@thomas-braun
so wie schon anfangs des Threads...
Bei mir lief iobroker eigentlich die ganze Zeit unauffällig. Ich habe noch einmal überlegt, seit wann ich die Probleme habe. Ich habe vor einigen Tagen meinen NibePi eingebaut und vor kurzem MQTT zum Datenaustausch aktiviert. Etwa seit dem habe ich Probleme. Kann es sein, dass mein NibePi meinen ioBroker mit Daten zumüllt und es dadurch zu Problemen kommen kann?

[Thomas Braun]

@mguenther Was auch immer ein Nibepi ist.

[mguenther]

@thomas-braun
:)
ist ein Zero W PI mit einer Node-Red Version drauf, die meine Nibe Wärmepumpe "ausliest". Hier im Forum hatte ich was dazugeschrieben.

@mguenther sagte in iobroker manchmal nicht erreichbar:

anscheinend immer bei einer dasWetter Instanz auftritt. Das will mir nicht in den Sinn...

dann deaktiviere die doch mal eine zeitlang

[mguenther]

@homoran
ja, ich hatte vorhin 2 von 3 Instanzen gestoppt. Eine läuft jetzt mal weiter mit einem Kreuzgetauschten Netzteil von meinem RaspberryMatic Pi4. Wenn ich da weiterhin Fehler bekomme, dann deaktiviere ich die auch noch und schaue, was passiert.

[mguenther]

@homoran
@thomas-braun
also... ich bin mal wieder nicht wirklich schlauer, aber....

1. Netzteil getauscht
2. Ich hatte vorher den schedule auf alle 20min bei einer dasWetter Instanz (ich habe 3) drin: DasWetter.0 immer ab der 7. Minute alle 20min, DasWetter.1 immer ab der 9. Minute alle 20min und DasWetter.2 ab der 11min alle 20min. Ich habe das nun in: alle 60min zur 7., 17. und 27. Minute geändert.

was soll ich sagen - keine Abbrüche mehr. Ich weiß nur nicht, ob es an dem Netzteil oder an den Instanzen lag. Bis jetzt keine Probleme mehr...

[Thomas Braun]

@mguenther

Mal blöd gefragt, wozu braucht man drei Instanzen für das Wetter? Ist das bei dir auf der Terrasse anders als zur Straße hin?

[mguenther]

@thomas-braun
ne - ich lass mir in meiner VIS 3 separate Wohnorte anzeigen - da, wo unsere Verwandschaft wohnt...

@homoran
@thomas-braun
Ich sollte aufhören, hier zu schreiben. Jedes Mal, wenn ich hier was schreibe und mich freue, kommt kurz danach wieder ein Absturz. So auch heute morgen:

bei der dasWetter.1 Instanz kam dann der selbe Eintrag und bei dasWetter.2 kam das:

2021-07-26 09:31:10.312 - error: unifi.0 (2747) fetchDevices: Returned data is not in valid format

auf der Konsole (den 2. Befehl habe ich etwa 5min später eingegeben):
