建立一個 Telegram 聊天機器人，建立步驟參考如下：
要建立 Telegram 聊天機器人首先需跟 @BotFather 對話，打開 Telegram，將畫面切至 Chats (對話) 的頁籤，並在上方搜尋 BotFather。
開始和 BotFather 對話
請在訊息框內輸入 /newbot (建立新的聊天機器人) 並送出，送出後 BotFather 會先詢問要設定的聊天機器人「英文代稱」！英文代稱結尾必須是「Bot」或是「_bot」結尾 ,看到：
Good. Now let’s choose a username for your bot. It must end in ‘bot’. Like this, for example: TetrisBot or tetris_bot，
命名完成後看到：
Done! Congratulations…
這時候就代表機器人建立成功囉
在對話內找到
Use this token to access the HTTP API:
後面有一串 Token，先務必先將它記下來並妥善保存！
若不慎遣失您的 Token 可以在 BotFather 輸入
/mybots 來查詢 token
將 IDBot 加入好友。
https://telegram.me/myidbot
這個 IDBot 是查找自己的 id，可以輸入 /getid 獲得；
<< 要取得token 與 chatid>> 要去node-red上修改
2) Node-Red 安裝Telegram 節點
node-red-contrib-telegrambot
修改Token
修改 chatid
3) 控制方法
按 Green , Red , Blue , Yellow , Off, Env 等inject (注入節點)
查看 PC上 telegram訊息 與手機上 telegram訊息
