@zenmanenergy Steve, I like your class example, could you point me towards any good reading to learn more about classes. I thought your comment about classes being under used was interesting.

Hi,
is GPIO16 proper for use with onewire?
I have an old software, where i used GPIO16 with Dallas DS18B20. Would say, I am sure that it worked some time ago, because I made a PCB with using this Pin.
Today I took the old code, compiled.....--> ..... On GPIO16 I can not find any DS18B20. Using GPIO5 all working fine.

Yep. 4,7k
hmmm..... found this: esp8266/Arduino#2383
Because I run out of IOs, I am looking now for another free IO for the OneWire.
Tried with GPIO10. But I have two NodeMCUs . One is running with onewire on GPIO10, the other not. Both NodeMCUs look similiar....

Ah ! Interrupts ... Then, no choice to swap pins ...
