Problem with multiple http get request
Posted: Sat Jul 10, 2021 8:29 amI have a problem with a Wemos D1 mini.
I try to make 2 Http Get Request to 2 different servers. I will update the temperature to an external website and to a local Domoticz server I have at home. The first http Request works but not the other. And I remove the first and just drive the other then work it so there is nothing wrong with the address itself. I would like help understanding what I do for the wrong or what it is too wrong on the code.
Maybe no good looking code but I'm a beginner.
And all SerialPrint is for trying to understand what is happening and not happening.
