my vote for Indigo as well !!!. Indigo ( http://www.indigodomo.com ) is the oldest, most flexible, up-to-date, affordable and best home automation (HA) software for Apple Mac ($100, $200 Pro). Most people, including me are running this on Mac Mini as a HA software-controler (better than Vera, or similar) and control INSTEON, Z-Wave, X10 devices and has great number of 3d party API plugins to control Philips Hue, Nest, Neatmo, Lutron, Honeywell, Sonos, Elk, Vera Bridge, Weather Underground, etc, etc. The control is either from Apple Mac, Website, iPhone, iPad. Definitively, much faster (instant), reliable, more powerful than IFTT if you are considering API. (IFTT is a very poor cousin compare to Indigo.) Also, there is much more users of Indigo than Control4. My vote is definitely for Indigo API doing first on Mac, before starting doing API for any other Apple based, related HA (Control4, Savant are great, but expensive from instalation dealers only).
