after making project 9 I successfully ran the code on ubuntu but when the temperature crossed the threshold there was an error from Twilio side with respect to sending the text sms to my cell
For convenience I kept the maximum_temp= 380
This error generally occurs if there is a mistake in authentication details passed.
Please check if the config file that you have saved has correct details and there is no typo in it.
@harshitadalawat an you please share a screenshot of your tem_sms.py code ?
I completed the project yesterday and I had to make slight change for Twilio to send the sms.
Share the screenshot and let us see.
