Hi @JDRoberts,
If Amazon echo/Alexa (or something else) becomes the main interface with your devices, don’t you think that they have already won the battle?
Doing the full HA integration with certain key devices (not only the voice) could be an easy task for the big player in a second phase of their strategy…
Just my 2 cents…
P.S. If you look at all recent articles about HA, Samsung/SmartThings is not even mentioned…
