Post: Hey there, I've bought the Raspberry Pi 1Wire and I'm trying to connect it to my Raspberry Pi 3. I've gone trough the steps as described My chip is detected I think. Output of i2cdetect -l is: i2c-1 i2c bcm2835 I2C adapter I2C adapter. The output of i2cdetect -y contains the number 18, as expected. When running (sudo) python 1wiretest.py (the code provided in the tutorial) I'm getting the following error: [pre][code]Traceback (most recent call last): File "1wiretest.py", line 2, in ow.init('localhost:4304') File "/usr/lib/python2.7/dist-packages/ow/__init__.py", line 224, in init raise exNoController ow.exNoController[/code][/pre] I'm also getting an error when booting my Raspberry Pi, telling me that my /etc/rc.local failed (this was after adding this line of code: sudo /opt/owfs/bin/owserver -c /etc/owfs.conf --pid-file /var/run/owfs/owserver.pid) I have changed it to sudo /usr/bin/owserver -c /etc/owfs.conf --pid-file /var/run/owfs/owserver.pid, since the path posted in the tutorial seems outdated, but I'm still getting the same error.

But when changing the line to server: device = /dev/i2c-1, I get a 'The site can't be reached, localhost refused to connect' in the browser.
