在SSID和PASSWORD宏定义中修改成自己的WIFI名称和密码。



#define SSID      "Itead_1(Public)"        //type your own SSID name

#define PASSWORD  "27955416"            //type your own WIFI password



接着，把刚才所取得的APIKEY，设备的ID值和传感器的ID值替换到程序相应的位置中。设备的ID值替换代码中DEVICEID的值，传感器的ID值替换代码中SENSORID的值。



// for yeelink api

#define APIKEY         "7bf75e6c2c8a17351d557f206f89fa2e"// replace your yeelink api key here

//replace the device ID and sensor ID for temperature sensor.

#define DEVICEID0       3047 //replace y**ice ID

#define SENSORID0       4285 //replace your sensor ID

//replace the device ID and sensor ID for humidity sensor.

#define DEVICEID1       3047 // replacey**ice ID

#define SENSORID1       26142 //replace your sensor ID
