Hello,
maybe i have anything wrong but cant make working onewire DS18B20 sensor with parasite power – bought genuine Dallas sensor and is same. With non parasite connection all is working good. Pullup is 4k7 but tries 2k, 1k, 10k (found as solutions).
Can anybody help me please?
Tried examples but with same result. Found solutions but without success.
Using Platformio, libraries
<OneWire.h>
<DallasTemperature.h>
<NonBlockingDallas.h>
Thanks to all.

Hi.
I’m not sure… This kind of issue is very difficult to troubleshoot.
Maybe the wiring is incorrect… or the data line is not “powerful” enough to power it via parasite mode.
I’m sorry that I can’t help much.
Regards,
Sara
