Wido2Yeelink
本帖最后由 Rockets 于 2017-4-6 17:18 编辑想请教下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

1、详述一下你的项目需求（想做什么，实现什么功能），YeeLink好像不是很好用
2、什么叫做一个设备的两个节点，比如不同传感器数值？ 同时读取两个传感器的数据吗？ Vash 发表于 2017-4-6 14:47
同时读取两个传感器的数据吗？
就一个传感器，温湿度传感器，同时把温度和湿度传到yeelink上 pATAq 发表于 2017-4-6 14:39
1、详述一下你的项目需求（想做什么，实现什么功能），YeeLink好像不是很好用
2、什么叫做一个设备的两个节 ...
http://api.yeelink.net/v1.0/device/356326/sensor/403687/datapoints、http://api.yeelink.net/v1.0/device/356326/sensor/403688/datapoints
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？ Vash 发表于 2017-4-6 14:47

读取两个传感器也可以啊，就是不知道咋写
