使用Bolt IOT的帶有蜂鳴器的電報比特幣通知器

描述

一旦比特幣價格大幅下跌并且您首先收到通知，擁有一個個人機器人來提醒您不是很好嗎？此外，在達(dá)到一定水平后，警報會上升，表明現(xiàn)在是投資的黃金機會。

先決條件：

1.螺栓物聯(lián)網(wǎng)課程

2.使用botfather創(chuàng)建一個電報機器人

3.比特幣價格API

讓我們開始吧：

1.硬件部分：

進行如圖所示的基本連接：

?

確保啟動 Bolt 并連接到 WIFI。綠燈應(yīng)亮。

2.軟件部分：

登錄 linux 或使用 PuTTY 登錄 Digital Ocean 的 VPS。

conf.py使用命令創(chuàng)建文件sudo nano conf.py。編寫以下代碼：

"""Configurations for alert.py"""
bolt_api_key = "XXXX"                 # This is your Bolt Cloud API Key
device_id = "XXXX"                    # This is the device ID and will be similar to BOLTXXXX where XXXX is some numbers
telegram_chat_id = "@XXXX"            # This is the channel ID of the created Telegram channel. Paste after @ symbol.
telegram_bot_id = "botXXXX"           # This is the bot ID of the created Telegram Bot. Paste after bot text.
threshold = 700000                       # Threshold beyond which the alert should be sent

alert.py使用命令創(chuàng)建另一個文件sudo nano alert.py。編寫以下代碼：

import requests, time, json, conf                    
from boltiot import Bolt       
                
mybolt = Bolt(conf.bolt_api_key, conf.device_id)

def get_bitcoin_price():
   URL = "https://min-api.cryptocompare.com/" # REPLACE WITH CORRECT URL
   response = requests.request("GET", URL)
   response = json.loads(response.text)
   current_price = response["INR"]
   return current_price

def send_telegram_message(message):
    """Sends message via Telegram"""
    url = "https://api.telegram.org/" + conf.telegram_bot_id + "/sendMessage"
    data = {
        "chat_id": conf.telegram_chat_id,
        "text": message
    }
    try:
        response = requests.request(
            "POST",
            url,
            params=data
        )
        print("This is the Telegram URL")
        print(url)
        print("This is the Telegram response")
        print(response.text)
        telegram_data = json.loads(response.text)
        return telegram_data["ok"]
    except Exception as e:
        print("An error occurred in sending the alert message via Telegram")
        print(e)
        return False


while True:
    current_price = get_bitcoin_price()
    if current_price <= conf.threshold:
        print("Bitcoin has exceeded threshold")
        message = "Alert! The current Bitcoin Price is " + str(current_price)
        telegram_status = send_telegram_message(message)
        response = mybolt.digitalWrite('0', 'HIGH')
        print(response)
        time.sleep(5)
        response = mybolt.digitalWrite('0', 'LOW')
    time.sleep(10)

該程序的作用是在價格低于閾值時觸發(fā)警報并發(fā)送電報通知。

保存程序并使用sudo python3 alert.py

3.輸出
