申请免费成为认证开发者
硬件：ESP8266-D1-mini，光照传感器BH1750；温湿度传感器DHT11或22，土壤水份检测模块
平台：Arduino, Blinker 2.5.0
实现功能：
1）驱动继电器进而控制门禁、风机、阀门、灯光等设备
2）根据土壤墒情自动浇水
3）按钮及时反映控制状态
问题：
1）不能实时反馈时间数据，比如我要实现设备动作的倒计时显示在Button6.text("set_time")
2）MQTT经常掉线，WiFi经常会离线状态
3）ESP有时会重启
4）开关按钮有时会返回press而不是on
5）最近1周数据为啥只有4天？
6) 在callback函数中用了Blinker.delay()就会出现很多问题
