emqtt VS MQTT Explorer

I do know a real world use for Erlang (it also surprised me when I investigated about it), but two of the biggest mqtt brokers are coded in erlang: emqx, vernemq. Source: about 1 year ago

EMQX is an open-source, highly scalable, and distributed MQTT messaging broker written in Erlang/OTP that can support millions of concurrent clients. As such, there is a need to persist and replicate various data among the cluster nodes. For example: MQTT topics and their subscribers, routing information, ACL rules, various configurations, and many more. Since its beginning, EMQX has used Mnesia as the database... - Source: dev.to / almost 2 years ago

EMQX(https://github.com/emqx/emqx) is an open-source project under Apache License 2.0, we don't think there are national borders for open source. The nature of its being open-source means it is developed, tested, and used by the open-source community worldwide. For a popular open-source project that has been downloaded by 15M times and adopted so widely globally for many years, it’s impossible to have a backdoor... Source: about 2 years ago

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. Source: 12 months ago

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. Source: about 1 year ago

Use MQTT Explorer to view and generate messages: http://mqtt-explorer.com/. Source: about 1 year ago

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. Source: over 1 year ago
