可能是我表达不够清晰，我想做一下事情：一个主控上挂LED3个（D2,D3,D4），人体D5,温湿度D6,土壤A2，蜂鸣 ...

可以的，在阿里云平台上创建一个产品，为它定义LED1，LED2，LED3，人体温度5等等的功能属性，每个功能都有特定的标识符，再为这个产品创建一个设备，这个设备会继承该产品的所有属性，操作这些标识符就能实现控制和获取信息，关联ESP32和设备，通过上报和订阅和标识符，就能控制ESP32上连接的设备

阿里云发布web以后。指示图标没有变化，数据已经配置了。开关都正常，就是图标没有反应，按道理关了是一种颜色，开了是一种颜色。但是怎么就没改变，。

您好楼主，我想问一下，我遇到这种情况应该怎么解决，我是直接复制你的程序代码的。
在用Arduino 1.8.9编译时候提示如下错误：
StaticjsonBuffer是Arduinokson 5中的一个类。请访问arduinokson.org/upgrade了解如何将您的程序升级到arduinokson。
我应该如何解决，谢谢

你好，请教一下，如果我需要控制两个led，那么回调函数该怎么写呢，一块esp32上有10个数字输出，我在其中两个引脚各连接一个LED。但LED的识别码是不同的，那么Json信息该如何解码呢。

这套代码在新版的阿里云Iot（现在的时间是2023-02-01）会有问题了，问题如下：
LED灯会一直被关闭

问题原因：
新版的阿里云Iot，在添加完设备后，会为设备自动定义如下主题，如下图所示：
https://mc.dfrobot.com.cn/forum.php?mod=attachment&aid=MTU0Mjc3fDJlMTg0ODU4ZWZmODIyZDllYjMyMjA1ZTBjZmRhYmI5fDE3NjE2MjM1Mjg%3D&request=yes&_f=.png
出现问题的地方是，当设备订阅这个主题：

/sys/a17x7FncZl0/DPR-LED/thing/event/property/post_reply

后
调用如下方法

/*需要操作的产品标识符*/
String Identifier = "LightStatus";

/*需要上报和订阅的两个TOPIC*/
const char * subTopic = "/sys/a17x7FncZl0/DPR-LED/thing/service/property/set";//****set
const char * pubTopic = "/sys/a17x7FncZl0/DPR-LED/thing/event/property/post";//******post

...

void callback(char * topic, byte * payload, unsigned int len){
  Serial.print("Recevice [");
  Serial.print(topic);
  Serial.print("] ");
  for (int i = 0; i < len; i++){
    Serial.print((char)payload[i]);
  }
  Serial.println();
  StaticJsonBuffer<300> jsonBuffer;
  JsonObject& root = jsonBuffer.parseObject((const char *)payload);
  if(!root.success()){
    Serial.println("parseObject() failed");
    return;
  }
  const uint16_t LightStatus = root["params"][Identifier];
  if(LightStatus == 1){
    openLight();
  }else{
    closeLight();
  }
  String tempMseg = "{"id":"+ClientId+","params":{""+Identifier+"":"+(String)LightStatus+"},"method":"thing.event.property.post"}";
  char sendMseg[tempMseg.length()];
  strcpy(sendMseg,tempMseg.c_str());
  client.publish(pubTopic,sendMseg);
}

void setup(){
  ...
  /*开机先关灯*/
  closeLight();
  
  /*上报关灯信息*/
  client.publish(pubTopic,("{"id":"+ClientId+","params":{""+Identifier+"":0},"method":"thing.event.property.post"}").c_str());
}
复制代码

在函数setup()中调用：

  client.publish(pubTopic,("{"id":"+ClientId+","params":{""+Identifier+"":0},"method":"thing.event.property.post"}").c_str());
复制代码

阿里云收到消息后，在这个主题“/sys/a17x7FncZl0/DPR-LED/thing/event/property/post_reply” 发送消息，在串口窗口，可以看到返回的参数是：

15:00:16.777 -> Recevice [/sys/a17x7FncZl0/DPR-LED/thing/event/property/post_reply] {"code":200,"data":{},"id":"12345","message":"success","method":"thing.event.property.post","version":"1.0"}
复制代码

可以看到，返回Json对象，根本没有属性

const uint16_t LightStatus = root["params"][Identifier];
复制代码

故这里得到 LightStatus 最终为0，根据下面的代码，回关闭LED。

  if(LightStatus == 1){
    openLight();
  }else{
    closeLight();
 ;
复制代码

跟离谱的是，接着下面的代码

 }
  String tempMseg = "{"id":"+ClientId+","params":{""+Identifier+"":"+(String)LightStatus+"},"method":"thing.event.property.post"}";
  char sendMseg[tempMseg.length()];
  strcpy(sendMseg,tempMseg.c_str());
  client.publish(pubTopic,sendMseg)
复制代码

又会在这个主题

const char * pubTopic = "/sys/a17x7FncZl0/DPR-LED/thing/event/property/post";//******post
复制代码

上发送消息，又引发回调函数 callback() 响应主题

/sys/a17x7FncZl0/DPR-LED/thing/event/property/post_reply
复制代码

然后造成一些循环，串口将一直输出：

15:00:12.029 -> Recevice [/sys/a17x7FncZl0/DPR-LED/thing/event/property/post_reply] {"code":200,"data":{},"id":"12345","message":"success","method":"thing.event.property.post","version":"1.0"}

复制代码

灯将一直被关闭。

在这里，希望官方看看是否更新先示例代码。
