HomeKitADK VS HAP-NodeJS

Sure, you just have to fork the HomeKit Accessory Development Kit code from GitHub

Yeah, I basically finished porting the Apple HomeKit ADK to use the SimpleLink SDK and FreeRTOS kernel. Just haven’t gotten around to uploading to GitHub yet. Sure I can help you get started.

Hi there, I build yocto and homekit ADK on my raspberry pi, and code examples to test it. I add a new service and new characteristic for the temperature sensor. When I execute it, I can pair the device and print information(manufacturer, ...) of the device on my iPhone. But iPhone can not get the value of temperature. logging on below. https://github.com/apple/HomeKitADK/issues/111 The same code is successful on Raspbian.

Apple released https://github.com/apple/HomeKitADK back in 2019

HomeKit has licensing restrictions that prohibit use of my hardware for certain applications -- unless you pay for some Apple Inc.'s MFi Program. Link.

FYI https://github.com/apple/HomeKitADK

This is designed to replace a Wi-Fi module in one of my ceiling fans, in order to add support for Apple HomeKit using the open-source ADK which I've already ported to run on the TI LAUNCHCC3235MOD evaluation board (more or less, will post all of this on GitHub soon). The dimensions and component placement are constrained to match the original board. I started out just writing new firmware for the original board, which uses a Kinetis K12 Cortex M4 MCU and GainSpan/Telit GS2200 Wi-Fi module, but I could not get the HomeKit ADK code and stack to fit in the 320KB program flash / 32KB SRAM on the MCU without substantial effort and debugging limitations. The GainSpan module has plenty of flash and SRAM, but unfortunately that company charges $7,000+ for the SDK to reprogram it.

Doing a bit of digging, I found the Charaacteristic definition in https://github.com/homebridge/HAP-NodeJS/blob/master/src/lib/definitions/CharacteristicDefinitions.ts. I'm still a bit new to Typescript... what would the best way / place for me to modify this Characteristic? Do I need to just make this change here and basically run a custom version of Homebridge?

Well, the API only provides m3 values, and the plugin you suggested is only displaying 2 decimals instead of 3 in homekit (most likely a homekit limitation; since in homebridge 3 [and even 4] decimals are listed, and the accuracy of the sensor seems to be 0.0001 - as listed on https://github.com/homebridge/HAP-NodeJS/blob/master/src/lib/definitions/CharacteristicDefinitions.ts )

HAP-NodeJS Pull: HomeKit Secure Video #920

My goto place regarding this is the HAP-NodeJS repository

They're related in that u/koushd contributed https://github.com/homebridge/HAP-NodeJS/pull/904 to Homebridge, which was completed and merged with many of their commits in https://github.com/homebridge/HAP-NodeJS/pull/920.

Yeah this appears to be the relevant discussion on it: https://github.com/homebridge/HAP-NodeJS/pull/918 I guess Raspbian does not ship with avahi by default.

I looked at libraries like HAP-NodeJS or HAP-python, but those seems focused on:
