I’m looking to use a zwave adapter (Z-Wave.Me ZME_UZB1 USB Stick), it’s properly detected but when i try to add any device with it, it does not seem to work. The biggest problem is I have no feedback (/home/homeassistant/.homeassistant/OZW_Log.txt does not exists), it complains about it in the home assistant logs, and i have no feedback on how adding / removing or operating the zwave network is going.
I then tried to change /opt/homeassistant/lib/python3.6/site-packages/python_openzwave/ozw_config/options.xml to force but it does not seem to make any difference.
Any idea on how i can get the openzwave log file to be written ? or to diagnose / reset anything that could be useful about openzwave ?
The error appear when i’m browsing to the zwave configuration item in the configuration menu.

If nobody have a solution i will have to try other home automation servers but that will make me
As a last attempt and before I have to commit this act of blasphemy, i will tag @anderson110@anon43302295 and @Tinkerer as I have been reading other z-wave topics and saw you bravely save people from different kind of z-wave problems. But feel free to ignore my message if you don’t have the answer for this one.
cd /home/homeassistant/.homeassistant/
touch OZW_Log.txt
chmod 777 OZW_Log.txt
that will create an empty file and make it world-writeable. It doesn’t solve the larger issue that HA isn’t creating that file in the first place. My guess is @Tinkerer is correct in asking if your permissions are correct on your ~./homeassistant/ directory.
Could not abolish the problem yet, but here is the extra info…
@Tinkerer : the directory seems ok but files does not exists
# ls -ald /home/homeassistant/.homeassistant/ /home/homeassistant/.homeassistant/OZW_Log.txt
ls: impossible d'accéder à '/home/homeassistant/.homeassistant/OZW_Log.txt': Aucun fichier ou dossier de ce type
drwxr-xr-x 1 homeassistant homeassistant 408 févr. 26 23:00 /home/homeassistant/.homeassistant/
And i also checked that homeassistant is running with the homeassistant process, but as a matter of trying superstitious things, i changed it to 777 also.
@ha_steve : I did not think of that. But unfortunately, while your suggestion get ride of the error message, no content is added during operations so i still have effectively no logs (except if i forcibly put stuff in the file i can check that it’s displayed on the zwave homeassistant web config page).
For example, if i run “add node” i can see in syslog that the call is made :
Feb 26 23:36:06 poinsart hass[24473]: INFO:homeassistant.core:Bus:Handling <Event call_service[L]: domain=zwave, service=add_node, service_data=, service_call_id=140420622509896-3>
Feb 26 23:36:06 poinsart hass[24473]: INFO:homeassistant.components.zwave:Z-Wave add_node have been initialized
Feb 26 23:36:06 poinsart hass[24473]: INFO:homeassistant.core:Bus:Handling <Event service_executed[L]: service_call_id=140420622509896-3>
But without the OZW_Log.txt it’s hard to understand why nothing gets added.
There is one more thing i can try : i can run a new homeassistant install on a different computer, see if i have the same result or if i can think of something while doing it.
I will try that this week, but don’t hesitate to tell me if you have other suggestions.
