Hallo Forum.

Aus meiner Sicht kann man für eine MQTT-Verbindung zum Broker in der AWS-Cloud den Keep Alive-Timer in unserer Node-RED-Konfiguration ausschalten bzw. auf 0 setzen:



Wie man in der IGW/936-Log-Datei sehen kann, beendet offensichtlich der AWS-MQTT-Broker ca. alle 30 Minuten die TCP-Verbindung, so dass der MQTT-Client des IGW/936 eine neue Verbindung aufbauen muss:

Code:
Jan 24 22:06:06 Disconnected from broker: mqtts://… iot.eu-central-1 …
Jan 24 22:06:22 Connected to broker: mqtts://… iot.eu-central-1 …
Jan 24 22:36:22 Disconnected from broker: mqtts:// … iot.eu-central-1 …
Jan 24 22:36:38 Connected to broker: mqtts:// … iot.eu-central-1 …
Jan 24 23:06:38 Disconnected from broker: mqtts:// … iot.eu-central-1 …
Jan 24 23:06:54 Connected to broker: mqtts:// … iot.eu-central-1 …
