💡 解决 ESP32 上传温湿度数据到阿里云的问题 🛠️

esp32连接上了阿里云但是就是温湿度传不进去

温室读获取是正常的串口显示的是这种东西，应该是传输的问题

/*这是我的代码*/麻烦大佬看看下，我用的是商城给的库
#include <WiFi.h>
#include <PubSubClient.h>
#include <ArduinoJson.h>
#include "DFRobot_Aliyun.h"
#include "DFRobot_DHT11.h"

你好，在吗，我想请教一下为啥我的激活不了设备o(╥﹏╥)o

看看你定义的标识符数据类型

星辰大海：//。，

看一下阿里云的日志服务，到底是阿里云物模型解析不到，还是没有发上去

我也是存在这个问题。阿里云IoT套件能够顺利的连接WiFi，但Web界面不能实时显示传送的温湿度数据。即使按照如下修改[backcolor=rgb(250, 250, 250)][font=微软雅黑]上报和订阅的两个TOPIC：[/font][/backcolor]
[backcolor=rgb(250, 250, 250)][font=微软雅黑]const char * subTopic = "/sys/a1XcjmmmPnM/sensor/thing/service/property/set";//****set[/font][/backcolor]
[backcolor=rgb(250, 250, 250)][font=微软雅黑]const char * pubTopic = "/sys/a1XcjmmmPnM/sensor/thing/event/property/post";//******post[/font][/backcolor][backcolor=rgb(250, 250, 250)][font=微软雅黑]依然不能够实时在阿里云的Web界面上实时显示曲线。[/font][/backcolor]不知道怎么解决。

把需要上报和订阅的两个TOPIC改下：
const char * subTopic = "/sys/a1XcjmmmPnM/sensor/thing/service/property/set";//****set
const char * pubTopic = "/sys/a1XcjmmmPnM/sensor/thing/event/property/post";//******post

- 没有更多了 -

求助esp32上传不了温湿度到阿里云
