Blinker 开发实例介绍——温室大棚
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

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")
目前设计就是这样的，倒计时定时可以通过定时页面显示
2）MQTT经常掉线，WiFi经常会离线状态
8266 ram不够，在上传数据到云端时会断开MQTT，再切换到http进行，上传完成后，即会从新连接mqtt
3）ESP有时会重启
看报错信息，程序问题，ram不足，供电问题都可能导致设备重启
4）开关按钮有时会返回press而不是on
长按就会触发press
5）最近1周数据为啥只有4天？
不清楚，建议过几天再看，如果还是只有近4天的，再联系我
6) 在callback函数中用了Blinker.delay()就会出现很多问题
回调函数中，不能有耗时的操作，任何单片机上都是如此 谢谢回复。回调函数的问题我正在解决中。
图表里面只能显示4个时间点，一直是这样。 修改后：
bool b5_state=false;
bool b6_state=false;
void button6_callback( const String & state){
BLINKER_LOG("get switch state: ", state);
if (state == "on" ){
b6_state=true;
}
else if (state == "off"){
b6_state=false;
digitalWrite(D8, LOW);
Button6.icon("fas fa-faucet");
Button6.text("阀门关");
Button6.print("off");
}
}
void loop(){
Blinker.run();
if (b5_state==true){
autodrip();
b5_state=false;
}
if (b6_state==true){
manudrip();
b6_state=false;
}
......
}
void manudrip(){
digitalWrite(D8, HIGH);
for (int i=set_time; i>=0; i--){ //增加for循环，b6按钮的时间实现倒计时显示
sprintf(buf2,"%d",i); //滑块返回设定时间
sprintf(dsk,"%s%s%s",buf1,buf2,buf3); //buf1=开,buf3=s
Button6.text(dsk);
Button6.icon("far fa-faucet-drip");
Button6.print("on"); //第一次调用显示龙头状态
Blinker.delay(1000);
if (b6_state==false)
break;
}
//Blinker.delay(set_time*1000);
digitalWrite(D8, LOW); //延时set_time*1000秒后自动停止D8控制的对象
sprintf(buf2,"%d",0);
sprintf(dsk,"%s%s%s",buf1,buf2,buf3);
Button6.text(dsk);
Button6.icon("fad fa-faucet-drip");
Blinker.delay(1000);
Button6.text("再按复位");
Button6.print("on");//第二次调状态
}
倒计时一旦开始（滑块set_time=10s），总是出现MQTT 不稳问题。
