Shambles
The whole "Smart Home" thing seems like a solution in search of a problem to me. My house works fine as it is, and I have no intention of spending thousands to automate my curtains. I suspect I share this attitude with a vast majority.
If these corporations can't agree on a single open standard they will be having this very argument in 10 years time, still proclaiming the Internet of Things is coming and selling a tiny number of proprietary devices to a tiny market.
Fail all round.
