I went through this exercise multiple times and a couple of unexpected errors kept occurring.
If the validation is skipped without publishing, the device and monitoring keep working correctly. Then, a similar error occurs building the cloud application, once AWS IoT starts publishing messages to the device. The device keeps rebooting after sending only one set of data, so the intervals become around 15 seconds (this is what it takes the device to reset and reconnect).

Also, the device lights are not being triggered when the states are changed to COOLING or HEATING (they remain off).
I hope this information is useful.
