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: about 1 year 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
