I finally found the problem!
During the tests to make my cert file work I probably checked "Variable SSL buffer length" don't see how else this could have been checked. That was the problem.

Yeap, stupid mistake I had mistakenly soldered a 100nF in Data line instead of 33pF

Thanks all ! I will have to implement one of the above

Thanks ESP_adokitkat

My hardware setup is with a pull-up 4k7 like it suggests and I assume it's ok. I can't read the thermometer, I get the errors
