Hi all, In a recent thread, I promised @Trying_to_learn that I would revisit a project I started quite a long time ago now, which is a replacement for the MQTT Explorer desktop app. So here is my first draft. It is still very basic but it demonstrates the principles. If you have anything you partic…

I'll compile an SFE (Windows) - that auto loads the front end upon launch, and will share the download on a PM - feel free to share (or advise me you are happy for me to post it here) Having a Node RED/UIB Powered MQTT explorer compliments my Gin on a Friday :smiley:

[image] marcus-j-davies: or advise me you are happy for me to post it here Yes, of course, go right ahead.

You aren't being paid enough. :wink: This sounds like a great project.

For me, MQTT Explorer is one of the best tools for development. It is lightweight, multi-platform, simple, and easy to use. Improving it would be awesome. Here are some things that I miss the most: Filter capabilities for payload data. Especially for big JSON messages. Scripting support like MQTT…

@TotallyInformation UIB/Node RED Powered MQTT Explorer in an SFE. AUTOLOAD file just fires up the default browser, and points to /mqtt-explorer [Screen Recording 2025-11-22 at 09.01.32] Though, your admin API v3 is bringing in node:inspector, which was not used, so had to remove it, as currently…

Your flow has at the end of it {"id":"d99e9240e9cdc815","type":"global-config","env":[],"modules":{"node-red-contrib-uibuilder":"7.6.0"}} So when I import it node-red asks if I want to install that version of uibuilder, but npm only has 7.5.0 so the install fails. I can install that version manua…

[image] marcus-j-davies: admin API v3 is bringing in node:inspector Ah, good spot, I'll have to check that. [image] Colin: 7.6.0 Oops! Thanks Colin. I did it on my dev PC of course which has the next version of uibuilder in it. My bad. It should all work fine with v7.5 anyway. I didn'…

[image] TotallyInformation: I didn't realise that the exported flow file includes version numbers. Neither did I till it failed when I was prompted to install it.

Just to be clear, this flow requires UIBUILDER? I see a missing node error, but its not clear if installing this node is all that is required, or more tweaking of other files as per the second post is required. I've been testing many MQTT Explorers, but never found one that works as cleanly as MQT…

Had a quick try. this looks good, especially as it can be made accessible remotely as a Web page using whichever preferred method.
