[gelöst] Erhalte keine Nahrichten mehr von MQTT devices nach Raspberry-Tausch

[FhemPiUser]

Hallo,
ich habe am 7.1. den Raspberry 3 für meine fhem-Installation durch einen Raspberry 4 ersetzt und natürlich die alte fhem-Konfiguration eingespielt. Alles funktioniert, nur von bestimmten MQTT-Devices (ESPHome-Geräte) sehe ich seit dem keine Nachrichten mehr in fhem (MQTT2-Server). Andere MQTT-Devices funktionieren.

Ich sehe auch, dass sich die fehlenden MQTT-Devices per WLAN verbinden und ich kann sie pingen. An der Netzverbindung liegt es also nicht.

Hat jemand eine Idee, woran das liegen kann?

Ein Beispiel ist das Gerät "pana_wz_ec6260bb8f88".

Neuer Raspi bedeutet in der Regel auch neue IP-Adresse.
D.h. hast du in den Devices die IP vom MQTT-Server angepasst?

[FhemPiUser]

Nein, die IP-Adresse vom alten Fhem-Server / Raspberry hatte ich übernommen. Die ist also gleich geblieben.

Ich hatte auch schon die Clients neu gestartet und fhem auch (auch update all). Hat alles nichts geändert.

[FhemPiUser]

Was heißt eigentlich, wenn das Gerät unter "retain" im MQTT2-Server auftaucht. Kommen dann doch Nachrichten an?

[frober]

Retain heißt nur, dass der Server den Payload solange behält bis ein neuer kommt.

Wenn es nur die ESPHome betrifft, sorry da kenne ich mich nicht aus. Evtl. im Device neu connecten...

[FhemPiUser]

Ich habe die esphome devices bereits neu gestartet, aber das hat nichts geändert. Bei den esphome devices hatte ich ja auch nichts geändert, es ging ja mit dem alten Raspberry.

Das einzige andere MQTT Gerät an dem MQTT2 Server ist evcc und das geht.

[frober]

Ich habe nichts von Neustart geschrieben.
In ESPHome die MQTT Verbindung neu starten, evtl. hat ESPHome einen Fingerprint o.ä. um den Server zu identifizieren (als Sicherheit).

[FhemPiUser]

Danke, aber ich wüsste nicht wie ich die mqtt verbindung neu starten kann außer durch trennen des esphome devices vom strom (neustart) und das habe ich gemacht. damit wird ja auch die mqtt verbindung neu gestartet, oder nicht?

[frober]

Naja, prinzipiell schon aber du siehst so nicht ob die Verbindung hergestellt wird.

Normalerweise sollte es funktionieren wenn du z.B. den Port neu eingibst und speicherst. Das sollte auch funktionieren wenn die Daten sich nicht ändern.

Gibt es in ESPHome eine Anzeige  "MQTT connected" o.ä.?

[FhemPiUser]

leider nein bzw nur mit aufwand. Ich müsste die esphome devices aus der klimaanlage ausbauen und per usb am rechner umkonfigurieren.

[frober]

Hmm, ohne Webserver im Device ist das schwierig.

Hast du schon mal im MQTT2_Server geschaut ob Daten ankommen?
Oben "Show MQTT traffic", oder mit Verbose 5 und Neustart eines Device im Fhemlog kontrollieren ob etwas zum Verbindungsversuch drin steht.

[FhemPiUser]

ja, aber leider kein Einzrag gefunden, der von den esphome devices kommen könnte

[rudolfkoenig]

Ich sehe auch, dass sich die fehlenden MQTT-Devices per WLAN verbinden und ich kann sie pingen. An der Netzverbindung liegt es also nicht.

Kann man sie auch vom neuen RPi pingen?
Laut nrclients Reading im mqtt2_Server ist aktuell nur ein Client verbunden.

[frober]

Hast du evtl. anstelle der IP des MQTT Servers den Hostnamen in ESPHome angegeben?

[FhemPiUser]

Ja, lassen sich vom neuen RPI pingen und nein, im ESPHome hatte ich die IP-Adresse des alten und neuen RPI (ist ja gleich) eingetragen.

Ich habe den Fehler gefunden. Oh man. Der neue Raspberry hatte sowohl LAN als auch WLAN aktiviert und das LAN interface hatte eine falsche (andere IP Adresse als früher und als der konfigurierte MQTT Server). Die richtige IP Adresse hatte das WLAN Interface konfiguriert. Hatte mich im Router bei der Zuordnung IP-Adresse MAC-Adresse verklickt. Anfängerfehler

Ich habe nun WLAN auf dem RPI deaktiviert und die richtige IP dem LAN Interface zugeordnet und schon geht alles.

Danke allen.
