HomeKit
Dear Apple, please for the love of god and the good of everyone, get together with Google and iron out a common protocol for this stuff. Don't make this one of your competitive technologies designed to fragment the world into Apple and not-Apple. Home automation is just dying to take off and there's a pile of gold for everyone if you just show a tiny bit of cooperation to get it started ... And you can all still sue each other afterwards if you like about the design of the light switches or whatever turns you on, but can we please just let the industry move forward first?
