Can somebody explain the advantages of using HomeKit vs some open standard like SmartThings uses, or WeMo etc? I'm not really up to date on any of those, but it would seem that:
1. No controller is needed for the devices to operate, so setup would be more straightforward.
SmartThings does seem to require a controller.
WeMo advantage: Open source, initially more options.
HomeKit advantage: Lots of support behind it, eventually will have many devices that integrate with each other.
I believe that in a year or two HomeKit will really shine. The current integration you see with Apple has slowly grown over the years. The way the phone, tablet, TV and computer work together has improved since the first remote app for the iPhone. This will only get better and include HomeKit. There are a lot of companies announcing support for HomeKit.
Yes there are lots of options. For me, I am tired of tinkering with everything and like the direction the Apple ecosystem is gelling. I have other projects I would rather tinker with.
