Minimalistic C library for Apple's HomeKit Accessory Protocol

libhap

License: MIT

Minimalist C library for with Apple HomeKit accessories.

Note: This is still in active development, but works well enough for simple accessories such as a light bulb.

External dependencies

• openssl >= 1.1.1
• avahi-client

Note: OpenSSL 1.1.1 is relatively new and is only available on releases such as Ubuntu 18.04+, Raspbian Buster, etc.

libhap itself includes these excellent libraries:

• nodejs/http-parser - MIT License
• mjansson/json - Public Domain

Building

make

Running example

./hap

Building (and installing) a library

make solib
sudo make install # Installs in /usr/local

make install PREFIX=/some/other/path # Install in ${PREFIX} instead

Using

The API is documented in src/hap.h

The example in src/main.c contains a few examples for how to create:

• A light-bulb accessory using the hap_light_builb_create() convenience function.
• An RGB light accessory using the hap_rgb_light_create() convenience function.
• A Bridge combining the accessories above.

To create more complex accessories, please read Apple's Using the HomeKit Accessory Protocol Specification to understand the relationship between accessories, services and characteristics.

The plan is to add many more convenience functions to ease usage.

libhap's Issues

libhap without avahi-client

Thank you for the lib. I trying to create an accessory based on OpenWRT (for old Kankun SP3 Smart Plug).
The OpenWRT already has a MDNS daemon (procd_add_mdns) and in the same time very limited in disk size.
Is it possible to make libhap without avahi?
Or maybe you can recommend some other library
