Node-RED 由Dashboard UI Buttom 控制 MQTT Out , 經由MQTT in 控制 Dashboard UI Text 與 Line Notify

執行畫面 127.0.0.1:1880/UI  

1) 設定 On LED , Off LED

設定 payload :  Light-emitting diode on  與  Light-emitting diode off

2) 設定 audio out 讓 LED 設定的 payload  Light-emitting diode on  與  Light-emitting diode off 能說出來

 3) 設定 MQTT Server 與 Topic

MQTT Server :  broker.mqtt-dashboard.com:1883

Topic  :  alex9ufo/led/led_event

 4) 設定 dashboard Text

 5)  取得 Line Notify 的 發行權杖 使得LEN ON , LED OFF 狀態可以隨時由手機APP LINE取得資訊

LINE結果 畫面

進入 https://notify-bot.line.me/zh_TW/ 登入

進入 發行權杖

指定 名稱 與 要Line通知的人 或 群組

將發行權杖 複製

檢視一下 發行的權杖是否active 

6) LINE 通知 的方法1

將剛才設定的 放入Name 與 Access Token 中

手機Line Notify 會送出 HEllo! LED Change 與一個貼圖 

7) LINE 通知 的方法2

設定2個function

function1

var date = new Date();
var h = date.getHours();
var m = date.getMinutes();
var s = date.getSeconds();
if(h<10){
    h = '0'+h;
}
if(m<10){
    m = '0' + m;
}
if(s<10){
    s = '0' + s;
}
msg.payload = msg.payload + ' --> Time:(' + h + ':' + m + ':' + s + ')' ;

return msg;


function 2
發行權杖 放入 Authorization':'Bearer 後面
A4wwPNh2WqB723dlfeQyyIAwtggn1kfZSI5LkkCdia1gB'};


msg.headers = {'content-type':'application/x-www-form-urlencoded','Authorization':'Bearer A4wwPNh2WqB723dlfeQyyIAwtggn1kfZSI5LkkCdia1gB'};
msg.payload = {"message":msg.payload};
return msg;
