Hi All,
I recently started playing around with OWFS using a DS9490 USB module and
have successfully connected a number of different 1-wire devices.
However, I am now trying to get external sensor support working with a HP03
pressure module which does not have a 1-wire interface.
I have managed to write custom code to read pressure values from this
device and I would like to integrate it into my 1-wire system, but can't
seem to get it working.
I searched this list and found a related post
http://sourceforge.net/p/owfs/mailman/message/31139475/ but there was no
resolution.
My config file is pretty basic:
# Temperature scales
Celsius
external
SCRIPT: pressure, HP30D, p10, 1, v, /var/tmp/baro, , ,
SENSOR: barometer, HP30D, "Pressure Sensor",
When I try to access the "barometer" directory, I get the following errors:
[root@server ~]# ls -l /mnt/1-wire/barometer
ls: cannot access /mnt/1-wire/barometer/family: No such file or directory
ls: cannot access /mnt/1-wire/barometer/pressure: No such file or directory
ls: cannot access /mnt/1-wire/barometer/type: No such file or directory
total 0
d????????? ? ? ? ? ? family
d????????? ? ? ? ? ? pressure
d????????? ? ? ? ? ? type
I'm just wondering if anyone managed to get external sensor support working?
Any help to get this working would be much appreciated.
Below is debug output from the 'owserver' and 'owfs' processes.
Thanks
David
