Yes, 100% success.
But my setup involves Home Assistance with Mosquitto MQTT Broker.
Also you will need all 3 security files for AWS such as *_CA.pem, *.pem.crt and *_private.pem.key
On the HE side I am using app/driver designed by Kevin Hawkins:
Support via Hubitat community beta threads
[OLD] MQTT app beta1 and pre beta2 - please use beta3 thread
You can contact me via PM on that forum @kevin
If you are interested in and have (or will set it up) Home Assistant with Mosquitto MQTT Broker
and of course, have all AWS required components I can provide you how to configure HA.
HE is pretty much straight forward.
