最近买了一个63块钱斐讯插排TC1，本来是有远程控制的，由于斐讯倒闭了所以只能当普通排插用。不过远程控制这点小功能可难不倒专业IT码农：），于是直接开干。

拆开外包装的样子，做工真心不错：

开拆，首先拆掉底部的两颗螺丝：

接着用平口螺丝刀翘途中沿线位置把所有底部卡口都撬开就可以开盖了：

先瞧瞧原来的主控

拆掉主控，技术还要多练，掉了一个焊盘

引脚定义，参考贴子
https://www.amobbs.com/thread-5715200-1-1.html

焊上排线

排线的另一端，自己人肉打了标 ：）

刚好手上有现成的nodemcu板子，接上

再接上一个温湿度传感器，功能多多益善

装回外壳，由于nodemcu体积有点大，只能这样放在外面了，幸好盖上盖子啥也看不到

网页端控制软件，aliyun IoT Studio拖拽出来的。云端能正常控制，温湿度也正常显示。到此搞定

下面是源代码：

阿里云端的配置，网上教程超级多，我就不一一介绍了。

建好一个产品，然后添加一个设备。在产品里面配置好“自定义功能”这些就是到时候nodemcu和控制端里面要用的字段：

设备详情页面，里面的ProductKey， DeviceName，DeviceSecret在esp8266代码里面需要用到

阿里云账号的区域，在代码里面要用到REGION_ID。我是上海地区的代码就填cn-shanghai

Password生成小工具是阿里云提供的，用于计算MQTT_PASSWD，或者根据规则自己算也可以。timestamp默认全用1234567890就可以

ESP8266代码，直接在Arduino里面写的，目标板子选nodemcu即可。两个###之间的是需要根据各自阿里云配置修改的地方
