Apple HomeKit is a framework for communicating with and controlling connected home applications. Dozens of devices can be built with HomeKit, but designing these products for the Apple protocol and navigating the approval process can be a daunting process. Learn how Silicon Labs can help dramatically reduce this complexity and mitigate risks. On-demand webinar: http://bit.ly/2hyikkx

2. 2 Silicon Labs Confidential
Introduction to Apple HomeKit
Apple HomeKit is a framework for communicating with and controlling connected
home accessories such as lights, locks and thermostats.
It enables users to discover, configure and control smart home accessories using
iOS devices.
It also supports remote access to accessories through iCloud when using Apple TV
or iPad as a gateway.

3. 3 Silicon Labs Confidential
 More than 30 device types can be
built with Apple HomeKit today:
 Sensors: Temperature, Humidity,
Smoke, Presence, CO etc.
 Controls: Light, locks, thermostats,
garage door openers, etc.
 Gateways: These connect sensors and
controls with applications

 HomeKit is not just a technology – but
an ecosystem:
 Technology providers such as Apple, Silicon
Labs, etc.
 Device vendors like: Apple, Philips, August,
Schlage, etc.
 Application developers
 System integrators
 Devices and applications are
interoperable, allowing more
advanced smart home applications
than proprietary systems
 Hunders of millions of potential users
