想请教下Yeelink上怎么实现同时连接一个设备的两个节点，用的设备是DHT11温室度传感器。例子中只是连接了一个节点，需要在哪里做些改进呢？ 我是初学 [mw_shl_code=cpp,true]#include <Adafruit_CC3000.h> #include <ccspi.h> #include <SPI.h> #include <dht11.h> dht11 DHT; #define DHT11_PIN 0 #define Wido_IRQ 7 #define Wido_VBAT 5 #define Wido_CS 10 Adafruit_CC3000 Wido = Adafruit_CC3000(Wido_CS, Wido_IRQ, Wido_VBAT, SPI_CLOCK_DIVIDER); // you can change this clock speed // Security can be WLAN_SEC_UNSEC, WLAN_SEC_WEP, WLAN_SEC_WPA or WLAN_SEC_WPA2 #define WLAN_SECURITY WLAN_SEC_WPA2 #define WLAN_SSID "ChinaNGB-Yd4fWw" // cannot be longer than 32 characters! #define WLAN_PASS "arrd2472" // For connecting router or AP, don't forget to set the SSID and password here!! #define TCP_TIMEOUT 3000 //#define CC3000_TINY_DRIVER #define WEBSITE "api.yeelink.net" #define API_key "87c0a2706cf9f5f5062a6ef3cb7b8ffc" // Update Your API Key.

2、什么叫做一个设备的两个节点，比如不同传感器数值？
一个设备，DHT11温湿度传感器，同时把温度湿度上传到yeelink。
另外你说的yeelink不好用？那有哪个比较好用的呢,另外的平台有开发文档吗？
