I have used OWFS service for a few years and its worked flawlessly
I am trying to get it to work on a new PI4 but i cant get to read any
sensors
I have followed the owfs service installation guide as in the past
pi@raspberrypi:~/Myideas $ sudo PYTHONPATH=/home/weewx/bin python
/home/weewx/bin/user/owfs.py --sensors
Traceback (most recent call last):
File "/home/weewx/bin/user/owfs.py", line 618, in <module>
main()
File "/home/weewx/bin/user/owfs.py", line 578, in main
ow.init(iface)
File "/usr/lib/python2.7/dist-packages/ow/__init__.py", line 221, in init
raise exNoController
ow.exNoController
Previously i think the only time i have had the above error is when i have
forgotten to plug the dalas adapter in to a USB port
it appears the service cant read my usb port
from the syslog file
