FWIW I tried following the instructions with a normal branded dash, and it is clear that the IoT button has a different firmware.<p>Differences:
* Amazon ConfigureMe network uses WPA2 for the IoT button. No encryption for the branded button.
* IoT button has extra fields (according to the documentation) that the branded does not. They are for a certificate, private key, REST endpoint, region, and a checkbox to agree to TOC.
