The flow shown in [this post](https://discourse.nodered.org/t/node-red-contrib-msg-queue-only-storing-not-forwarding-w-active-connection/44274/11) may be useful to you. It provides guaranteed delivery of MQTT messages to the broker. It can save messages over a reboot or node-red restart if required.
