based on what it is compatible with, it look like it will replace the wink, smarthome, the hue and who knows what else. It sounds like a good deal if you have a lot of hubs plugged into the router. I just hope you will be able to control the smart devices remotely with the new echo. I guess we really will not know the specifics until it is actually released.
as much as it will make things easier, I will stick with what I have for a little while longer otherwise it would be throwing money away when I stick the hubs I have in the closet.
