MQTTX VS MQTT-Explorer

This section will introduce how to use Neuron to collect data from FINS TCP devices, upload the collected data to EMQX, and view it using MQTTX.

Next, we open MQTTX, create a new connection, copy the JWT output when JWKS Endpoint starts to the Password field, and click Connect in the upper right corner to connect.

Again, we can use MQTTX or any other MQTT client to publish MQTT data to the demo/sensor topic. Those data will be processed by the rule. For example, we publish the following data to the topic with a 30 seconds interval, and the two minutes data is like this:

Among these, the MQTTX open-source project stands out as a fast-growing client tool that offers a modern chat-style interface, full MQTT 5.0 support, and a rich set of features that provides a great user experience. With three versions available - Desktop, Command Line, and Browser - MQTTX can fulfill your MQTT testing requirements in diverse scenarios. Undoubtedly, MQTTX is among the top MQTT client tools of 2023.

Here are a few alternatives: http://mqtt-explorer.com/ https://mqttx.app/

Next, we will demonstrate the use of Clean Session with the open-source cross-platform MQTT 5.0 desktop client tool - MQTT X.

MQTT connections are initiated from the client to the broker. Any application or device running the MQTT client library is an MQTT client. The MQTT Broker handles client connection, disconnection, subscribe (or unsubscribe) requests, and routes messages up on receiving publish requests.

MQTT X is an open-source cross-platform desktop client. It is easy to use and provides comprehensive MQTT 5.0 functionality, feature testing, and runs on macOS, Linux and Windows. It also provides command line and browser versions to meet MQTT testing needs in different scenarios.

In this post, we are not going to dig into the programming SDKs. We will try to demonstrate MQTT retained messages using the open-source cross-platform MQTT 5.0 desktop client - MQTT X.

Use MQTT 5.0 client tool - MQTT X as another client to test message sending & receiving.

Quote from MQTT Explorer

Sounds like you're on a good path tracking the problem to aws, not the esp. First of all, I'd try to make it work with a "proven" solution, then move on to your own implementation. I have had good success using http://mqtt-explorer.com/ on windows to diagnose a similar situation. Mqtt explorer gives you very granular control over endpoints and topics, so might be helpful to you too.

I would suggest using Mqtt explorer (http://mqtt-explorer.com/) to see how often the sensor updates its values. This as a first step to narrow down the problem.

Use MQTT Explorer to view and generate messages: http://mqtt-explorer.com/

For MQTT debugging, I like MQTT explorer

You can write test programs to send very specific messages to simulate errors, or simulate entire components that aren't written yet. There are also free programs like MQTT Explorer that will let you browse the message traffic, generate messages manually, log whatever you cant, and even graph your values if you happen to send numerical values (that is really cool when you do some long-term testing).

To use a local server can let you control all details of your full messaging chain. Try other clients can make you away from the ill behaviors or bugs of specific client. I recently demonstrate how easy a free MQTT client (MQTT explorer) send to a free MQTT database on Windows 10 in my video.

A useful tool is MQTT Explorer. You can connect to your broker and see what changes when you use the light through an app or switch or whatever. This should help you understand the manner in which the light talks with mqtt. Once you think you have understood it, you can use explorer to publish test messages to see if it works as desired.
