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 wuji 发表于 2019-4-18 13:36

检查下程序上报的逻辑 本帖最后由 时间都去哪了 于 2019-7-3 17:33 编辑
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。 您好，我想问一下手机APP一直下载不了，有遇到同样的情况吗？有解决办法吗？ 楼主很给力 努力加油奋斗

阿里云IoT之灯光控制
能否信息我一下，有偿服务，谢谢 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：
attach://154277.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);
}
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"];
if(LightStatus == 1){
openLight();
}else{
closeLight();
}
String tempMseg = "{\"id\":"+ClientId+",\"params\":{\""+Identifier+"\":"+(String)LightStatus+"},\"method\":\"thing.event.property.post\"}";
char sendMseg;
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());
}
在函数setup()中调用：client.publish(pubTopic,("{\"id\":"+ClientId+",\"params\":{\""+Identifier+"\":0},\"method\":\"thing.event.property.post\"}").c_str());
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 {"code":200,"data":{},"id":"12345","message":"success","method":"thing.event.property.post","version":"1.0"}
可以看到，返回Json对象，根本没有属性const uint16_t LightStatus = root["params"];
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();
;
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;
strcpy(sendMseg,tempMseg.c_str());
client.publish(pubTopic,sendMseg)
又会在这个主题
const char * pubTopic = "/sys/a17x7FncZl0/DPR-LED/thing/event/property/post";//******post
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
然后造成一些循环，串口将一直输出：
15:00:12.029 -> Recevice {"code":200,"data":{},"id":"12345","message":"success","method":"thing.event.property.post","version":"1.0"}
15:00:12.236 -> Recevice {"code":200,"data":{},"id":"12345","message":"success","method":"thing.event.property.post","version":"1.0"}
15:00:12.338 -> Recevice {"code":200,"data":{},"id":"12345","message":"success","method":"thing.event.property.post","version":"1.0"}
15:00:12.476 -> Recevice {"code":200,"data":{},"id":"12345","message":"success","method":"thing.event.property.post","version":"1.0"}
15:00:12.649 -> Recevice {"code":200,"data":{},"id":"12345","message":"success","method":"thing.event.property.post","version":"1.0"}
15:00:12.853 -> Recevice {"code":200,"data":{},"id":"12345","message":"success","method":"thing.event.property.post","version":"1.0"}
15:00:13.060 -> Recevice {"code":200,"data":{},"id":"12345","message":"success","method":"thing.event.property.post","version":"1.0"}
15:00:13.161 -> Recevice {"code":200,"data":{},"id":"12345","message":"success","method":"thing.event.property.post","version":"1.0"}
15:00:13.369 -> Recevice {"code":200,"data":{},"id":"12345","message":"success","method":"thing.event.property.post","version":"1.0"}
15:00:13.506 -> Recevice {"code":200,"data":{},"id":"12345","message":"success","method":"thing.event.property.post","version":"1.0"}
15:00:13.677 -> Recevice {"code":200,"data":{},"id":"12345","message":"success","method":"thing.event.property.post","version":"1.0"}
15:00:13.882 -> Recevice {"code":200,"data":{},"id":"12345","message":"success","method":"thing.event.property.post","version":"1.0"}
15:00:13.985 -> Recevice {"code":200,"data":{},"id":"12345","message":"success","method":"thing.event.property.post","version":"1.0"}
15:00:14.090 -> Recevice {"code":200,"data":{},"id":"12345","message":"success","method":"thing.event.property.post","version":"1.0"}
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。
