OZW_Log.txt getting big

Configuration
1

My Zwave log keeps expanding with my apprx 30 zwave devices. Is there a way to disable logging every zwave detail? Or would it be possible to move the logfile to a backup dir every now and then, for example using an automation?

I created a .sh file with this command:

mv -f OZW_Log.txt ./archive/OZW_Log.txt

then I defined this in configuration.yaml

shell_command:
  cleanlog: ./cleanlog.sh

And finally created an automation:

- id: '1234'
  alias: clean the log                              
   initial_state: true
   trigger:
   - platform: time
     at: "00:00:00"
  action:
  - service: shell_command.cleanlog

But is does’n seem to work because the data element is missing for the action. (what should I define as data element to call a shell script?)

edit options.xml and set

<Option name="logging" value="false" />

You don’t have to stop the logging completely. If you prefer, you can choose a log level in options.xml - see Open ZWave Config Options. I have mine set to 4 (warning or higher) like this:

< **Option** name="logging" value="true" />
< **Option** name="SaveLogLevel" value="4" />

Additionally, if you want to rotate the log. You are probably better off doing it outside of HA using the OS native logrotate utility. Instead of an automation (IMO)

Create a file like /etc/logrotate.d/openzwave

/home/homeassistant/.homeassistant/OZW_Log.txt {
  daily
  missingok
  rotate 5
  compress
  notifempty
  create 0644 homeassistant homeassistant
}
