    What is causing this, is there a way to prevent this?

    Could it be a fake?

    Other question:
    Is there a way to connect ( and use) a DS18B20 (or other equivalent
    chip) on NodeMCU esp8266 ??

    Not familiar with NodeMCU, but other ESP frameworks (eg ESPHome) have
    support. So I would expect there's a library for that.
