Glenn:
Thank you for your response.
apt show ow-python <<< does not show anything
apt show python-ow <<< returns 3.2p3+dfg1-2
apt show owserver returns info so I assume that owserver is installed.
Do I need to uninstall things as per the referred post??
- Start from a fresh system (no other owfs components installed) and
install owserver and ow-shell:
$ sudo apt install owserver ow-shell
- Delete (as root) the hyper-verbose default debian /etc/owfs.conf file
and use this minimal config:
server: usb = all
server: port = 4304
- Enable and start the owserver
$ sudo systemctl stop owserver
$ sudo systemctl enable owserver
$ sudo systemctl start owserver
Current {OWFS}
interface = u
driver = user.owfs
[[sensor map]]
outTemp = /uncached/28.6E175D040000/temperature
Do I just need to change the "u" to localhost:4304 or any other changes
need to be made??
Sorry for all of the questions as I said that I design hardware and am
familiar with Windows. Linux is a new experience for me.
Then again, I might as well spend the time at home learning new things. :)
Thanks again.
