Why can't I receive email and push notifications

Please properly format your posted code…


If you format your code correctly, I’ll explain why it doesn’t work.


did you add email widget on your phone?

@Cetin_Gursel As stated… backticks NOT commas or apostrophes :stuck_out_tongue: I Fixed it.

This is in your setup()… but that is not going to do any good there :stuck_out_tongue: It should be in the getSendData() function, after reading the sensor.

However, you have no provision that prevents it from constantly sending every second until the temperature drops below 26… thus your email and notifications will get blocked to prevent spamming.

Yes, I did

Yes, I did it


Thank you very much for your prompt response
Yes! I moved it to getSendData() and it works! I received email and notifications. But you are right it sends every second. I should find some way to delay alerts like every 20min
thanks again
