I have RPi with 1 Wire Pi Plus. I connected DS18B20 to ground, OW and +5V pins by RJ12.
I installed SW by follow steps: https://www.abelectronics.co.uk/kb/article/1/i2c--smbus-and-raspbian-linux - it looks OK.
there is a bit of problem with step 6. The "/opt/owfs/bin/owserver" does not exist, but I think no excactly problem because command service owserver status says "runnig".
I tried command "sudo i2cdetect -y 1" and found out only device 18 and nothing more. Is it OK or I shloud see 1wire device.
Python program in step 8 crashed.
Nothing is in directory /mnt. Shall I create directory/mount point /mnt/1wire manually?
Why I do not see DS18B20?
