I am using several ds18b20 for projects, but every now an then some give
temp 85.0 ° ?? without CRC error?
What is causing this, is there a way to prevent this?
Other question:
Is there a way to connect ( and use) a DS18B20 (or other equivalent
chip) on NodeMCU esp8266 ??
Many thanks in advances

Could it be a fake?

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