@adityapy2409 you can refer replit link to understand better

Hello @adityapy2409

The error “no module named email_conf” suggests that the email_conf module is not found in your current environment. This could be because the file email_conf.py is either missing or not in the correct directory.

Here is the corrected and properly formatted code.

email_conf.py File

@adityapy2409 Basically you are getting error because you had not implemented email_conf.py and trying to access in below code the variable like:-

mybolt = Bolt(email_conf.API_KEY, email_conf.DEVICE_ID)
mailer = Email(email_conf.MAILGUN_API_KEY, email_conf.SANDBOX_URL, email_conf.SENDER_EMAIL, email_conf.RECIPIENT_EMAIL)

so it is giving error.

Solution:-
you need to implement email_conf.py in your project directory which is given below:-

main.py:-

from boltiot import Email, Bolt
import json
import time
import email_conf

# MAILGUN_API_KEY = "9f05bd1a685f32634b240a62d7d1e9e9-fe9cf0a8-31799d4a"
# SANDBOX_URL = "Mailgun by Sinch"
# SENDER_EMAIL = "test@" + SANDBOX_URL
# RECIPIENT_EMAIL = "adityapy2409@gmail.com"
# API_KEY = "726eeba8-b349-4995-ae3a-eb3fb01521e7"
# DEVICE_ID = "BOLT6370758"

min_lim = 300
max_lim = 330

mybolt = Bolt(email_conf.API_KEY, email_conf.DEVICE_ID)
mailer = Email(email_conf.MAILGUN_API_KEY, email_conf.SANDBOX_URL, email_conf.SENDER_EMAIL, email_conf.RECIPIENT_EMAIL)

while True:
    print("Reading")
    response = mybolt.analogRead('A0')
    data = json.loads(response)
    print(str(data['value']))
    try:
        sensor_value = int(data['value'])
        if sensor_value > max_lim or sensor_value < min_lim:
            print("Request for email")
            response = mailer.send_email("Alert", "The Current temperature sensor value is " + str(sensor_value))
            response_text = json.loads(response.text)
            print(str(response_text['message']))
    except Exception as e:
        print("Error")
        print(e)
    time.sleep(10)

2.email_conf.py

MAILGUN_API_KEY = "9f05bd1a685f32634b240a62d7d1e9e9-fe9cf0a8-31799d4a"
SANDBOX_URL = "Mailgun by Sinch"
SENDER_EMAIL = "test@" + SANDBOX_URL
RECIPIENT_EMAIL = "adityapy2409@gmail.com"
API_KEY = "726eeba8-b349-4995-ae3a-eb3fb01521e7"
DEVICE_ID = "BOLT6370758"

i am open to discuss furthur if any error occur

Hi @adityapy2409

The code in the main,py file seems correct. In the emai_conf.py file just enter the correct sandox url and run the code again. To get the sandbox url go the mailgul, in the sending section you find the sandbox url.

Do try this and let us know. If you still face any issue, please feel free to get back to us.

Problem Explanation
hii @adityapy2409
You’re encountering an error because the email_conf.py file is missing from your project directory. This file is essential because it contains the necessary configuration variables such as API keys and email addresses, which are being accessed in your main script.

Solution

You need to create and implement the email_conf.py file in your project directory. Here’s how to do it:

  1. Create email_conf.py

This file will store all your configuration variables.

email_conf.py:

MAILGUN_API_KEY = "9f05bd1a685f32634b240a62d7d1e9e9-fe9cf0a8-31799d4a"
SANDBOX_URL = "Mailgun by Sinch"
SENDER_EMAIL = "test@" + SANDBOX_URL
RECIPIENT_EMAIL = "adityapy2409@gmail.com"
API_KEY = "726eeba8-b349-4995-ae3a-eb3fb01521e7"
DEVICE_ID = "BOLT6370758"

  1. Update main.py

Ensure your main.py script imports these variables from email_conf.py.

main.py:

from boltiot import Email, Bolt
import json
import time
import email_conf

# Set your sensor value limits
min_lim = 300
max_lim = 330

# Initialize Bolt and Email instances using configurations from email_conf.py
mybolt = Bolt(email_conf.API_KEY, email_conf.DEVICE_ID)
mailer = Email(email_conf.MAILGUN_API_KEY, email_conf.SANDBOX_URL, email_conf.SENDER_EMAIL, email_conf.RECIPIENT_EMAIL)

while True:
    print("Reading sensor value")
    response = mybolt.analogRead('A0')
    data = json.loads(response)
    print(f"Sensor value: {data['value']}")
    try:
        sensor_value = int(data['value'])
        if sensor_value > max_lim or sensor_value < min_lim:
            print("Sending alert email")
            response = mailer.send_email("Alert", f"The current temperature sensor value is {sensor_value}")
            response_text = json.loads(response.text)
            print(f"Email response: {response_text['message']}")
    except Exception as e:
        print("Error occurred")
        print(e)
    time.sleep(10)

Explanation

  • email_conf.py: This file contains all your configuration variables (API keys, email addresses, etc.). By storing these in a separate file, you keep your main code cleaner and more secure.
  • main.py:
    • Imports: It imports necessary modules and the email_conf configurations.
    • Initialization: Initializes the Bolt and Email instances with the configurations from email_conf.py.
    • Main Loop: Continuously reads the sensor value, checks if it’s within the specified limits, and sends an email alert if it’s outside those limits.
