First thing, either run weewx or use PYTHONPATH=/usr/share/weewx
python /usr/share/weewx/user/owfs.py
You can't run them both (ie: stop weewx if you use PYTHONPA)TH
weewx.conf
station_type = OWFS
is correct.
[OWFS]
interface = u
That's telling weewx that the driver is on the usb (u) interface
That's not what you have, I believe what you want is...
[OWFS]
interface = localhost:4304
under [[sensor_map]] you're going to need to tell it what sensors you
have and what you want them to show as; and under [[sensor_type]] you
may need to refine an entry, except for temperature where you can
accept the hardcoded default.
Shutdown weewx for this next step, remember you can only access the
1-wire bus from one process at a time.
So this is where
sudo PYTHONPATH=/usr/share/weewx python /usr/share/weewx/user/owfs.py
--iface localhost:4304 --readings
comes into its own.
from that output, find what you want amongst the values returned and
then use ...
PYTHONPATH=/usr/share/weewx python /usr/share/weewx/user/owfs.py
--iface localhost:4304 --reading /10.67C6697351FF/temperature
to test it out, or be bold and plug it straight into weewx.conf.
You possibly want
[[sensor_map]]
outTemp = /10.67C6697351FF/temperature
If more explanation is required then open
/usr/share/weewx/user/owfs.py and read the comments in there, it may
expand on the wiki entry or my summary above?
Once you have weewx.conf setup, restart weewx with the old init method
/etc/init.d/weewx stop
/etc/init.d/weewx start
If you just want to see what's weewx is picking up in the packets then
use, for the short term only...
/usr/bin/weewxd /etc/weewx/weewx.conf
but DON'T use the direct method while weewx is running, always stop it
for direct sensor access. (ie no PYTHONPATH=/usr/share/weewx...
anything)
