Request https with esp8266
Posted: Thu Jun 18, 2020 6:01 pmI made a temperature sensor that sends sends the temperature to Thingspeak and I also want it to send and email if the temperature is more than 28 degrees, but I dont know how to do the https part and the tutorials I found weren't working or I couldn't understand.
I already have a link that if I open(ifttt), it sends an email but I have trouble with making the esp8266 opening the link.
Can someone help me what do I need in the if loop or am I doing it completely wrong?
Thanks for any help.
