I am going to get started on some smart home stuff. I am trying to decide which platform(s) to go with. Here is what I have: Apple TV 4 Amazon Echo Dot Hue starter kit (hub and two bulbs) Nest thermostat 2nd gen I'd like to keep going with lights, plug in outlets, and maybe in wall switches. I have heard that Alexa can now act as a hub for some products, as can the ATV. I am not sure if the current gen Dot can act as a hub or if I would need the full size Echo. Also, if I use my Hue stuff with Alexa can I also use it with HomeKit or is it one or the other? Lastly, with what I already have is it even worth looking in to something like the Wink Hub? Really just looking for some direction before I start buying things. Thanks for answering some new guy questions!
