Works with Apple HomeKit

If you plan to develop or manufacture a HomeKit accessory that will be distributed or sold, your company will need to be enrolled in the MFi Program.

MFi licensees get access to:

  • HomeKit Accessory Protocol Specification (commercial version).
  • Third-party SDKs for commercial development.
  • “Works with Apple HomeKit” certification and tools.
  • Logo artwork and identity guidelines.

Get your apps ready for Matter

With iOS 15 SDK beta, you can now start testing your smart home apps with Matter, the unifying open connectivity standard designed to increase the compatibility of smart home accessories so they work seamlessly with your devices. Existing HomeKit APIs automatically work with Matter-enabled accessories, so you don’t need to make any changes to your iOS or iPadOS apps that support HomeKit. Find out more about Matter standard and open source implementation on GitHub.
