- Mon Jul 13, 2015 6:04 am #23128 Make sure that you are using the correct onewire library. You mentioned that you've had it working with the arduino. The ESP8266 has its own onewire library. In my debian configuration it's at:
.arduino15/packages/esp8266/hardware/esp8266/1.6.4-673-g8cd3697/libraries/OneWire/

I'm aware of the esp8266 lib location and have remove all onewire lib except the one I downloaded to avoid confusion.

@torntrousers, will test GPIO4 when I got home.

Thanks both for the help, hopefully will solve this issue.
Will update once I have done the test.

It is indeed the pin swap issue, use GPIO 4 instead of 5 and it is working perfectly!

Thanks both for the help, cheers!
