HomeKit, Apple's software framework for communicating with and controlling connected accessories in a user's home, currently works with about a hundred certified devices, Reuters said Friday.
By contrast, there are currently about 250 devices that are certified to work with Alexa, thanks to Amazon's open-systems approach and even financial incentives for some partners.
But HomeKit, which debuted alongside iOS 8 in September 2014, now has an agile competitor in Amazon's Alexa voice-controlled digital assistant which can also control smart accessories in the home with a few spoken words. The Reuters report outlines some of the requirements Apple imposes on device makers who wish to become HomeKit-certified.
