苹果在2014年推出的HomeKit智能家居平台的确给人眼前一亮的感觉。随着时间的推移，国外的黑客对HomeKit该逆向的逆向，结果也都汇总到了git。本着折腾到死的极客心态，从网上淘了一块树莓派进行测试。
0×01 基本工具
硬件在某宝上都有卖的，加起来不到300块
| 硬件: |
|---|
| 32G SD卡 |
| 2.5V电源线 |
| Raspberry pi3 |
| 两根杜邦线 |
| LED灯 |
| 保护壳 |
联动HomeKit的工程在git上找到两个，都是基于nodejs的，这边先测试的是HAP-NodeJS
| 软件 |
|---|
| raspbian |
| https://github.com/nfarina/homebridge |
| https://github.com/KhaosT/HAP-NodeJS |
0×02 安装
先解决依赖
# apt-get install avahi-daemon avahi-discover libnss-mdns libavahi-compat-libdnssd-dev build-essential -y
# service avahi-daemon start
增加nodejs源
curl -sL https://deb.nodesource.com/setup_6.x | sudo -E bash -
# apt-get install nodejs
克隆源代码
git clone https://github.com/KhaosT/HAP-NodeJS.git
安装node-gyp
$ sudo npm install -g node-gyp
然后切换到HAP-NodeJS文件夹下，运行
node Core,js缺哪个库安装哪个库
最后安装
npm install python-shell
打开iPhone手机的HomeKit就能看到伪造的智能设备了
在accessories的目录下新建一个LivingLight_accessory.js，代码如下
//Light_accessory.js
var PythonShell = require('python-shell');
// HomeKit types required var types = require("./types.js") var exports = module.exports = {}; var execute = function(accessory,characteristic,value){ console.log("executed accessory: " + accessory + ", and characteristic: " + characteristic + ", with value: " + value + "."); } exports.accessory = { displayName: "Living Light", username: "1A:5B:3C:4A:5E:FF", pincode: "031-45-154", services: [{ sType: types.ACCESSORY_INFORMATION_STYPE, characteristics: [{ cType: types.NAME_CTYPE, onUpdate: null, perms: ["pr"], format: "string", initialValue: "Living Light", supportEvents: false, supportBonjour: false, manfDescription: "Bla", designedMaxLength: 255 },{ cType: types.MANUFACTURER_CTYPE, onUpdate: null, perms: ["pr"], format: "string", initialValue: "Oltica", supportEvents: false, supportBonjour: false, manfDescription: "Bla", designedMaxLength: 255 },{ cType: types.MODEL_CTYPE, onUpdate: null, perms: ["pr"], format: "string", initialValue: "Rev-1", supportEvents: false, supportBonjour: false, manfDescription: "Bla", designedMaxLength: 255 },{ cType: types.SERIAL_NUMBER_CTYPE, onUpdate: null, perms: ["pr"], format: "string", initialValue: "A1S2NASF88EW", supportEvents: false, supportBonjour: false, manfDescription: "Bla", designedMaxLength: 255 },{ cType: types.IDENTIFY_CTYPE, onUpdate: null, perms: ["pw"], format: "bool", initialValue: false, supportEvents: false, supportBonjour: false, manfDescription: "Identify Accessory", designedMaxLength: 1 }] },{ sType: types.LIGHTBULB_STYPE, characteristics: [{ cType: types.NAME_CTYPE, onUpdate: null, perms: ["pr"], format: "string", initialValue: "Light 1 Light Service", supportEvents: false, supportBonjour: false, manfDescription: "Bla", designedMaxLength: 255 },{ cType: types.POWER_STATE_CTYPE, onUpdate: function(value) { console.log("Change:",value); if (value) { PythonShell.run('/python/light1.py', function (err) { console.log('Light1 On Success'); }); } else { PythonShell.run('/python/light0.py', function (err) { console.log("Off Success"); }); } }, perms: ["pw","pr","ev"], format: "bool", initialValue: false, supportEvents: false, supportBonjour: false, manfDescription: "Turn On the Light", designedMaxLength: 1 },{ cType: types.HUE_CTYPE, onUpdate: function(value) { console.log("Change:",value); execute("Test Accessory 1", "Light - Hue", value); }, perms: ["pw","pr","ev"], format: "int", initialValue: 0, supportEvents: false, supportBonjour: false, manfDescription: "Doesn’t actually adjust Hue of Light", designedMinValue: 0, designedMaxValue: 360, designedMinStep: 1, unit: "arcdegrees" },{ cType: types.BRIGHTNESS_CTYPE, onUpdate: function(value) { console.log("Change:",value); execute("Test Accessory 1", "Light - Brightness", value); }, perms: ["pw","pr","ev"], format: "int", initialValue: 0, supportEvents: false, supportBonjour: false, manfDescription: "Doesn’t actually adjust Brightness of Light", designedMinValue: 0, designedMaxValue: 100, designedMinStep: 1, unit: "%" },{ cType: types.SATURATION_CTYPE, onUpdate: function(value) { console.log("Change:",value); execute("Test Accessory 1", "Light - Saturation", value); }, perms: ["pw","pr","ev"], format: "int", initialValue: 0, supportEvents: false, supportBonjour: false, manfDescription: "Doesn’t actually adjust Saturation of Light", designedMinValue: 0, designedMaxValue: 100, designedMinStep: 1, unit: "%" }] }] }
然后在HAP-NodeJS下新建python文件夹，新建light1.py,用来开启灯
import RPi.GPIO as GPIO GPIO.setwarnings(False) GPIO.setmode(GPIO.BOARD) GPIO.setup(16, GPIO.OUT) GPIO.output(16, 1) #GPIO.cleanup()
light0.py用来关闭灯
import RPi.GPIO as GPIO GPIO.setwarnings(False) GPIO.setmode(GPIO.BOARD) GPIO.setup(16, GPIO.OUT) GPIO.output(16, 0) #GPIO.cleanup()
重新运行node Core.js即可在HomeKit看到新建的Living Light
把这个添加,pincode就是031-45-154
硬件连接
我这边用的是物理接口的16口和34口
0×03 测试
后记
这里有个前提条件是树莓派和iPhone在同一个子网上,如果想从外网控制就得需要映射公网WEB服务器或者是第三方物联网WEB的形式。而如果想将树莓派作为智能家庭网络的中心，后期还有很多工作要做，比如服务开机启动,连接继电器，线路改造，车库门，温度感应器，电视，摄像头等，有机会再继续聊吧
