I've recently started looking at web-enabled smart home devices (light switches, security cameras, etc). There are lots of products on the market, each brand with its own iOS app, and little to no cross-brand integration. When HomeKit was announced a couple years ago, I thought it was positioned to be an integration hub. But that seems not to have happened. And very little was said about HomeKit at WWDC yesterday. Am I missing something, or is HomeKit dead in the water?
