Sending email when temp. crosses threshold

1

When I execute my python code of 'send email when temp. crosses threshold then it is showing an error
“Expecting value:Line 1 column 1 (char 0)”
Anyone please help me

Can you provide a screenshot of your code?

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

minimum_limit = 300 #the minimum threshold of light value
maximum_limit = 600 #the maximum threshold of light value

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 ("Sensor value is: " + str(data[‘value’]))
try:
sensor_value = int(data[‘value’])
if sensor_value > maximum_limit or sensor_value < minimum_limit:
print(“Making request to Mailgun to send an email”)
response = mailer.send_email(“Alert”, "The Current temperature sensor value is " +str(sensor_value))
response_text = json.loads(response.text)
print("Response received from Mailgun is: " + str(response_text[‘message’]))
except Exception as e:
print (“Error occured: Below are the details”)
print (e)
time.sleep(10)

Try running the program after removing the lines
"response = mailer.send_email(“Alert”, "The Current temperature sensor value is " +str(sensor_value))
response_text = json.loads(response.text)
print(“Response received from Mailgun is: " + str(response_text[‘message’]))”.

Change the minimum_limit to 500 and run the program. Check if you get an email about the alert.

5

now it is showing "Reading sensor value "but not showing any value while my wifi module is on

6

Ohh! it is showing sensor value but i did not get any email alert

7

But in this case I am not getting the above error (“Line1 column1(char0)”)

8

Now add "response = mailer.send_email(“Alert”, “The Current temperature sensor value is " +str(sensor_value))”.
You should receive email alerts now.

I too got the same issue. But the problem is not solved. I didn’t get a mail regarding the ALERT

@rahulsaran542,

Can you share the screenshot of your code and screenshot of the output?

Also, add a print statement after json.loads and check the response from Bolt Cloud.

response_text = json.loads(response.text)
print (response_text)

check the apikey of mailgun you may have writen it wrongly check your conf file

12

same issue here; still not solved.

13

Same issue, not able to figure it out

14

I think I also faced the same issue. Check your email_conf.py file.
check if you correctly typed sender_email as test@sandbox_url

Hi @mabhijit.ec17,

Please share the screenshot of your conf file and blur some part of the credentials.
