Folks, I'm stuck. The story: I have MQTT and use it to move messages between machines. One of which is my Public_IP address. Yet, if I run MQTT Explorer it says that topic is empty. Strange as it is published to that topic. See piccies. (Follow red line for how it gets published.) [Screensho…

It isn't to do with one's IP it is only specific IPs that give the problem. When one publishes "58.169.129.172" to a topic (any topic) mqttexplorer shows {}. I think a clue is that if you click on the value and look in the right hand side it says Decoded SparkplugB [image] See MQTT-Explorer 0.4…

Ah, seems I am running an OLD (discontinued) version. Can't find an update at the SNAP site. :cry: Sorry folks. (If you can help me get a newer one.) Ubuntu 22.04 LTS

If you mean mqttExplorer then I am running the snap version latest/stable 0.4.0-beta4 on Ubuntu 24.04 and I have seen no issues.

[image] Colin: 0.4.0-beta4 I believe that IS the latest. Thomas long ago moved on from the project I believe and it is no longer being developed. One day I may have the time to complete my Node-RED version of something similar! Scrub that, there is a "beta6" version. But it only lists a si…

[image] TotallyInformation: One day I may have the time to complete my Node-RED version of something similar! Yes please!

Could you elaborate on how I get it? If/when I go to SNAP all I see is the existing version I have listed.

[image] Colin: If you mean mqttExplorer then I am running the snap version latest/stable 0.4.0-beta4 on Ubuntu 24.04 and I have seen no issues Indulge me then. Get your public IP address and broadcast it to a topic. (Say Public_IP) and look at what MQTT Explorer says is in the channel.

[image] Colin: Yes please! Yes, well, rather a lot going on just now and I'm afraid this has dropped down the priority list somewhat. I see how inspired I feel. :slight_smile: Right now, I've FINALLY gotten round to trying to document setting up Cloudflare Zero Trust to use with Node-RED and…

Thanks. Did command and that Fixed it.
