It’s difficult to convey the benefits of home automation to someone who has never experienced it. To address this challenge, Apple has begun rolling out an interactive HomeKit experience in 46 of its retail stores around the world. You’ll be able to use an iPhone, iPad, or Apple Watch to control virtual HomeKit accessories displayed on a screen. While not as impressive as the real thing, it should at least give you an idea of how HomeKit works and how you might integrate it into your house. Other Apple stores will feature a non-interactive HomeKit demo.
