OZW_log.txt remains empty

Hello,

I want to troubleshoot a Z-Wave issue as all my Aeotec Smart Switches are acting a bit funny but my OZW_Log.txt is always 0kb and empty. If I remove the log file and reboot Hass.io, the file is re-created automatically but always empty.

I’m running HassOS 2.12
|arch|armv7l|

|dev|false|
|docker|true|
|hassio|true|
|os_name|Linux|
|python_version|3.7.3|
|timezone|Europe/Amsterdam|
|version|0.92.2|
|virtualenv|false|

Thanks!
