Home Accessory Protocol

PS. Character = Characteristic

Device - HomeKit end device (swith, camera, etc)

  • mDNS name: MyCamera._hap._tcp.local.
  • DeviceID - mac-like: 0E:AA:CE:2B:35:71
  • HomeKit device is described by:
    • one or more Accessories - has AID and Services
    • Services - has IID, Type and Characters
    • Characters - has IID, Type, Format and Value

Client - HomeKit client (iPhone, iPad, MacBook or opensource library)

  • ClientID - static random UUID
  • ClientPublic/ClientPrivate - static random 32 byte keypair
  • can pair with Device (exchange ClientID/ClientPublic, ServerID/ServerPublic using Pin)
  • can auth to Device using ClientPrivate
  • holding persistant Secure connection to device
  • can read device Accessories
  • can read and write device Characters
  • can subscribe on device Characters change (Event)

Server - HomeKit server (soft on end device or opensource library)

  • ServerID - same as DeviceID (using for Client auth)
  • ServerPublic/ServerPrivate - static random 32 byte keypair
