Amazon echo duplicates wreaking havoc with HA interactions

I have figured out the ‘magic’ required to fix the above reference problems between HA and the echo devices.

The fix I have found is to do the following:

remove all devices in the echo device list.
deregister all of the echo devices, and add one of them back.
scan for devices again, and the duplicates will go away!

I tore out my hair trying to figure out why it was goofin with me for a couple days!
