Introduction to

Oberon HomeKit SDKs

2

We believe that smart home devices should be trustworthy and a joy to use.

With Apple HomeKit, one can easily

set up and control smart devices.

We provide everything you need to add HomeKit support to your device.

User experience Simple and standardized installation process Dedicated Home app for all devices Siri voice commands out of the box

Security and privacy End-to-end with state-of-the-art cryptography Access from Internet is optional, not required

Connectivity Bluetooth Low Energy (BLE) and IP (WiFi, Ethernet)

Why support HomeKit?

Home App & Standard Interface

4

A central point of

organization for your

connected home

Controllers iPhone, iPad, iPod, and Apple Watch provide a generic HomeKit User Interface out of the box iOS API allows anyone to implement HomeKit apps

Smart home devices Apple defines the protocol for smart home devices Device manufacturers must implement this protocol (on the device side)

What is already there?

5

HomeKit protocols are hard to implement Designed for radical end-to-end security

HomeKit security is strong Usually needs fast processors with large memories

Speed and memory sizes can be critical Scaling down to low-cost microcontrollers requires massive investments into optimizations

Challenges for Smart Devices

Where no other HomeKit Implementation goes!

Works with ≈14 KB RAM and ≈50 KB flash Simple application logic included in these numbers, but not the BLE stack Enables practical use on SoCs with ≥32 KB RAM

Feasible even on low-cost 16 MHz Cortex-M0

Footprint: Even for BLE SoCs

Where no other HomeKit Implementation goes!

Works with ≈20 KB RAM and ≈80 KB flash Simple application logic included in these numbers, but not the IP stack nor the buffers for TCP stack and TCP connections Enables practical use on SoCs with ≥100 KB RAM Memory requirements depend on supported HomeKit profiles

Footprint: Even for WiFi SoCs
