Hello everyone,  
I am experimenting with my new BW16 and trying to connect a Dallas DS18B20 temperature sensor.

I came across this thread: [Does BW16 support OneWire communication?](https://forum.amebaiot.com/t/does-bw16-support-one-wire-communication/962), but it seems to be outdated.

I have tried using the standard OneWire libraries as well as some modified ones. Additionally, I attempted to create a custom protocol from scratch, but it turned out to be more complex than I expected.

Is there any reliable way to read temperature from this sensor using the BW16?

Any guidance or suggestions would be greatly appreciated.

I am using arduino ide.

Thanks in advance!
