Hell all, I've run into an interesting error that results in sensors disappearing altogether, resulting in the error:
File "/usr/lib/python2.7/dist-packages/ow/__init__.py", line 271, in __init__ self.useCache( self._useCache ) File "/usr/lib/python2.7/dist-packages/ow/__init__.py", line 417, in useCache for n in owfs_get( self._usePath ).split( ',' ) ] ) File "/usr/lib/python2.7/dist-packages/ow/__init__.py", line 159, in _get raise exUnknownSensor(path) ow.exUnknownSensor: '/' Sure enough, my 1Wire directory is empty except the bus. Killing owfs, owserver and owhttpd and attempting to restart using the same commands I do at startup yields: DEFAULT: owlib.c:(56) No valid 1-wire buses found After rebooting, everything is fine again, until I run the questionable script. So the first question is how to reinitialize after fail without rebooting. The next is how to not have it fail in the first place. I see mention here, but no solution: http://owfs-developers.1086194.n5.nabble.com/Bug-in-re-init-ing-Python-ow-module-td4442.html What I'm using in owpython is pretty basic, and trimming out other code is really: import ow ow.init('localhost:4304') for sensor in ow.Sensor('/').sensorList(): # do stuff Interestingly, if I have this in a function like: def myowfsfun(args): ow.init('localhost:4304') for sensor in ow.Sensor('/').sensorList(): #do stuff if __name__ == "__main__": myowfsfun(args) I can run the function via the script file until the cows come home. If I import it into another script, e.g.: import owfslib owfslib.myowfsfun(args) and then run that script, it barfs immediately. Ideas?
