MQTT-Device falsch als 'offline' gekennzeichnet

[wk]

Ist es ein Fehler nur bei mir oder kennt ihr dies?
Bei mir wird immer mal wieder einer meiner MQTT-Devices als offline angezeigt obwohl er ganz normal funktioniert.
Heute habe ich einmal ein list eines Rolladen gemacht, der seit 3Uhr nachts offline sein soll, aber um 8Uhr ganz normal gefahren ist.

Dieses "offline" kommt daher, dass der Shelly - warum auch immer -  nicht innerhalb der angekündigten Zeit unter dem "LWT"-Topic (../online) gesendet hat. Über die Gründe mag ich grade nicht spekulieren...

[wk]

Ich kenne mich mit MQTT nicht sehr gut aus, aber bisher habe ich bei den Shellies das LWT-Topic nur nach einen Neustart gesehen.
Vielleicht kann man es mit dem announce-command triggern.

[Beta-User]

In der Regel braucht man das nicht, es wird einfach ein "bin da"-Signal gesendet und dann startet der "offline" (LWT-) Timer im Server neu. Offenkundig kommt das "bin da"-Signal eben nicht an.

Vermutlich ist einfach die WLAN-Verbindung (einmal mehr) "nicht optimal"...

[wk]

Danke, dann wird es wohl daran liegen.

Übrigens hat ein set announce das Device wieder online gebracht.

[rudolfkoenig]

Dieses "offline" kommt daher, dass der Shelly - warum auch immer -  nicht innerhalb der angekündigten Zeit unter dem "LWT"-Topic (../online) gesendet hat.

Um das etwas zu praezisieren:
- das LWT (aka Last Will and Testament, beinhaltet Topic+Message) wird vom Server gepublisht, wenn die Verbindung zum Client abbricht. Das kann auch der Server durchfuehren, wenn die zugesagten keepalive Pakete nicht rechtzeitig ankommen.
- das Protokoll spezifiziert nicht, dass der Client unter dem LWT-Topic online oder was Vergleichbares senden muss/soll, geschweige denn gibt es hierfuer ein Timeout.

Unter dem Strich bleibt es aber dabei, dass der Shelly nach dem MQTT-Connect freiwillig kein online:true gesendet hat.
