NodeRED-based MQTT Browser
I’ve recently started building stuff with NodeRED, which I really enjoy. Since I’m using MQTT as the central message bus for my system, I find myself regularly in need of knowing the current state of my MQTT topics. There are a couple of tools around, for instance MQTT.fx, which are specifically built for this purpose; but I found that MQTT.fx likes to cause high CPU load when the topic scanner thingy is running. So I’m looking for an alternative, and I thought, why not build it in NodeRED? So that’s what I did.
