Wenn Du schon ein nodered laufen hast, machst du eben alles darüber ohne groß darüber nachzudenken, wie es denn ohne gehen würde. In der 2er-Software stehen nur noch die Logs in der Ramdisk. Alle anderen Werte und die openWB-Konfiguration sind im MQTT-Broker. Einen Flow, der ein MQTT-Topic an einen http-Endpoint rausreicht, ist nicht kompliziert:
Der obere Flow abonniert ein MQTT-Topic und schreibt den sich immer ändernden Wert in einen flow-globalen Speicher. Der untere stellt einen http-Endpoint bereit, der den flow-globalen Speicher auf Anfrage ausgibt.
