极客DIY:如何用Siri与树莓派“交互”

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 -

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",

  },{

        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

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
