There's no doubt Apple is working on some form of home automation similar to the Amazon Echo or Google voice. Personally, I can't justify these types of devices in my home yet. I just feel there's not enough necessity and options to make my life any more convenient, aside from adjusting the thermostat or controlling lighting.
But I would be interested to see what Apple does differently when they do release their version of home automation. And by that time, hopefully Siri is revamped completely, as she would be a huge part of home automation using voice.
