esp-homekit

Apple HomeKit accessory server library for ESP-OPEN-RTOS.

See esp-homekit-demo for examples.

Building for ESP-IDF 4.x

In ESP-IDF >= 4.0 there is a SPI flash write protection that checks if area written to is inside writable parition. Haven't figured out yet how esp-homekit can modify parition table automatically, so for the time being you need to disable that check in menuconfig: go to Component config -> SPI Flash driver -> Write to dangerous flash regions and set it to "Allowed".

Building for ESP-IDF >= 5.0

You need to add a custom partition of type data and subtype "homekit" and at least 4KB (0x1000) in size for HomeKit data storage. Put this into partitions.csv file in your project:

# ESP-IDF Partition Table
# Name,   Type, SubType, Offset,  Size, Flags
nvs,      data, nvs,     0x9000,  0x5000,
phy_init, data, phy,     0xe000,  0x1000,
homekit,  data, homekit, 0xf000,  0x1000,
factory,  app,  factory, 0x10000, 1M,

Enable custom partitions in project configuration (sdkconfig):

CONFIG_PARTITION_TABLE_CUSTOM=y
CONFIG_PARTITION_TABLE_CUSTOM_FILENAME="partitions.csv"

QR code pairing

You can use a QR code to pair with accessories. To enable that feature, you need to configure accessory to use static password and set some setup ID:

homekit_server_config_t config = {
    .accessories = accessories,
    .password = "123-45-678",
    .setupId="1QJ8",
};

The last piece of information you need is accessory category code. You can find it in mDNS announcement in accessory logs

mDNS announcement: Name=Sample LED-1692md=MyLEDpv=1.0id=16:92:CE:D4:EE:7Ac#=1s#=1ff=0sf=1ci=5 Port=5556 TTL=4500

(notice "ci=5" <- this is accessory category code)

Or just find value of category enum you set in main accessory:

  HOMEKIT_ACCESSORY(.id=1, .category=homekit_accessory_category_lightbulb, .services=(homekit_service_t*[]){

(notice "homekit_accessory_category_lightbulb" <- this is accessory category code)

Then you need to generate QR code using supplied script:
