小度音箱+esp8266做语音控制开关

可用:插板，esp-01s继电器模块，usb转串口ttl模块、https服务器，小音箱。

大概原理：

https开关状态查询接口提供在服务器上，esp-01s烧录编写的固件可以连接wifi后轮询这个接口，并根据接口返回的状态打开或关闭继电器。在小技能平台上创建开关技能https提供服务器oauth2.0接口和遵循dueros智能家具协议的开关控制接口。这样，通过小度真机测试模式，小度可以打开开关https服务器打开开关接口，修改开关状态，间接控制开关开关。

大概过程：

(1)插板改造，把esp-01s继电器模块的常开始连接到插板的一线上。

（2）esp-01s可以使用nodemcu固件，直接lua开发，简化过程。

关于nodemcu固件，可以去https://nodemcu-build.com/在线编译，通过填邮箱、选择需要的模块、点击开始构建后，过会会收到包含固件下载地址的邮件。之前在这里编译过，当时选择了模块（adc,enduser_setup,file,gpio,http,mqtt,net,node,tmr,uart,wifi,tls），选定的模块，在lua相关脚本可用于脚本api，api文档地址https://nodemcu.readthedocs.io/en/master/。

关于固件烧录，esp-01s供电为3.3v，usb转ttl供电为5v，这里烧录时做了一个转接板连接，用asm1117 3.3v稳压器3.3v（usb转ttl带了3.3v电源，但没用，有些数据显示可能会烧坏，没有尝试)，RST与GND连接微动开关重启，GPIO0与GND拨动开关用于切换下载模式。连接后，打开NodeMCU-PyFlasher-4.0-x64.exe，115200选择串口和固件，Quad I/O，点击刷写，等待完成。连接后，打开NodeMCU-PyFlasher-4.0-x64.exe，115200选择串口和固件，Quad I/O，点击刷写，等待完成。如果不正常，试几次，建议短线连接。

（3）写入lua程序。

换用ESPlorer，选择串口，115200，打开串口，根据前转接板上的微开关重新启动，刷固件将初始化文件系统。命令线显示在软件的右侧，命令或脚本写在左侧。print("hello")并选择发送，发送到命令行，执行后显示结果hello。

这个时候可以写需要的。init.lua脚本，通过upload上传，写入esp-01s，按微动开关重启，nodemcu自动加载init.lua脚本执行，连接wifi，请求接口。

通过修改接口返回值，可以检测控制开关。

-- //init.lua print('hello')  -- wifi连接 wifi.setmode(wifi.STATION) station_cfg={} station_cfg.ssid="changeme" station_cfg.pwd="changeme" station_cfg.auto=true station_cfg.save=true wifi.sta.config(station_cfg) print(wifi.sta.getip()) -- //wifi.sta.disconnect()  -- ap模式，手机连接此wifi，到192.168.4.1配置wifi enduser_setup.start(     function()         print("enduser conn wifi as:" .. wifi.sta.getip())     end,     function(err, str)         print("enduser conn wifi err #" .. err .. ": " .. str)     end )  -- //print(uart.setup(0, 9600, 8, 0, 1, 1 ))  -- gpio0控制继电器，对应nodemc的pin 3，gpio2控制板载led，对应4 pin1 = 3 pin2 = 4 gpio.mode(pin1,gpio.OUTPUT) gpio.mode(pin2,gpio.OUTPUT) gpio.write(pin1,gpio.HIGH) gpio.write(pin2,gpio.HIGH)  myurl = "https://test.xxxxxxx.com/test/led.php"  mytimer = tmr.create() mytimer:alarm(5000, tmr.ALARM_AUTO, function()     ip = wifi.sta.getip()     if (ip == nil) then         print('wifi not connect...')         return     else         print(wifi.sta.getip())     end      print('http req led.php...')     http.get(myurl, nil, function(code, data)         if (code < 0) then             print("HTTP request failed...")         else             print("HTTP request succ...", code, data)             if (data == "00") then                 gpio.write(pin1,gpio.LOW)                 gpio.write(pin2,gpio.LOW)             elseif (data =="01") then                 gpio.write(pin1,gpio.LOW)                 gpio.write(pin2,gpio.HIGH)             elseif (data =="10") then                 gpio.write(pin1,gpio.HIGH)                 gpio.write(pin2,gpio.LOW)             elseif (data =="11") then                 gpio.write(pin1,gpio.HIGH)                 gpio.write(pin2,gpio.HIGH)             else                 print('led nop...')             end         end     end)     collectgarbage() end)  -- //mytimer.stop() 
<?php     # led.php  function getRedis($host = '127.0.0.1', $port = 6379, $db = 0) {   $redis = new Redis();   $redis->connect($host, $port);   $redis->select($db);   return $redis;  }    function getLed() {   $redis = getRedis('127.0.0.1', 6379, 0);   $led = $redis->get("led");   $redis->close();   return $led;  }    function setLed($led) {   $redis = getRedis('127.0.0.1', 6379, 0);   $redis->set("led", $led);   $redis->close();  }    $m = $_SERVER['REQUEST_METHOD'];  $t = isset($_REQUEST['t']) ? $_REQUEST['t'] : '';  if ($m == 'GET') {   if (empty($t)) {    $led = getLed();    if (!empty($led)) {     echo $led;    } else {     echo 'none';    }    exit;   }  }      if ($m == 'GET' && $t == 'ui') {     } else {   echo 'nop';   exit;  }    $led = isset($_REQUEST['led']) ? $_REQUEST['led'] : '';  $sw = isset($_REQUEST['sw']) ? $_REQUEST['led'] : '';  $sw = isset($_REQUEST['sw']) ? $_REQUEST['sw'] : '';  $msg = '';  if (!empty($led)) {   setLed($led);   $msg = 'set led = ' . $led .

（4）在小度技能平台，创建我的开关，配置服务里配置各url地址和值。

授权信息配置部分配置oauth2.0权限，设备云信息配置开关接口，如：

授权地址：https://test.xxxxxx.com/oauth2.0/authorize.php

Client_Id：191223d5e1bcb5f9e51bca66113ce3a1

Token地址：https://test.xxxxxx.com/oauth2.0/token.php

ClientSecret：191223d5e1bcb5f9e51bca66113ce3a2

WebService：https://test.xxxxxx.com/iot/dueros.php

这里oauth2.0只简单实现功能，dueros.php按协议实现简单功能。

（5）真机测试，开启技能调试模式，手机小度app上看设备，应该是会显示出此设备（原先直接向小度发语言提示没找到设备），向小度发语言“打开开关”，开关被打开。
