HomeKit on ESP8266
ESP01

Lưu tạm:

Chương trình chính trong HomeKIT dùng cho khóa cửa.

Trong đó, bổ xung thêm từ code ví dụ của thư viện:

1. Tự khóa lại sau 10s khi mở khóa cửa.

2. Trên ESP01 đổi sang cổng duy nhất không có tình trạng thay đổi lúc khởi động là RXD (GPIO3).

 * HAP section 8.38 Switch

 * An accessory contains a switch.

 *

 * This example shows how to:

 * 1. define a switch accessory and its characteristics (in my_accessory.c).

 * 2. get the switch-event sent from iOS Home APP.

 * 3. report the switch value to HomeKit.

 *

 * You should:

 * 1. read and use the Example01_TemperatureSensor with detailed comments

 *    to know the basic concept and usage of this library before other examples。

 * 2. erase the full flash or call homekit_storage_reset() in setup()

 *    to remove the previous HomeKit pairing storage and

 *    enable the pairing with the new accessory of this new HomeKit example.
