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

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 本帖最后由 njwy1978 于 2022-6-7 19:33 编辑
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。即使按照如下修改上报和订阅的两个TOPIC：
const char * subTopic = "/sys/a1XcjmmmPnM/sensor/thing/service/property/set";//****set
const char * pubTopic = "/sys/a1XcjmmmPnM/sensor/thing/event/property/post";//******post依然不能够实时在阿里云的Web界面上实时显示曲线。不知道怎么解决。
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 看看你定义的标识符数据类型
你好，在吗，我想请教一下为啥我的激活不了设备o(╥﹏╥)o
