Missing zwcfg_....xml file

Hi
Looking for help as I read a lot here and there and tried many things over the last 3 weeks without success.

Target
I’m migrating my fully operational Zwave network operated under Jeedom towards HA.
I want to handle automations triggered from zwave peripherals in NodeRed.
In particular, I need to be able to read the scene_data so i can define which type of press occured on the ZRC-90.

My config
RPI3
HassOS 4.17

Achievements so far
It took me some time to figure out that there are several ways to run Zwave (native Zwave / openzwave beta / zwave to mqtt).
I tried the 2 first ones and got it working up to a certain level:

  • USB stick well recognize
  • remotec ZRC-90 and Fibaro motion sensor added and reporting well to HA. With OpenZwave, I can even see the scene data (1 press, 2 press, key hold and key released).
    When I tail -f the OZW_log.txt logfile, I can see the node_id of each zwave device and I see activity when I press a button or shake the motion sensor…

What I fail to achieve
in order to get the scene_data from ZRC-90, I followed these instructions: https://www.home-assistant.io/docs/z-wave/device-specific/#remotec-zrc-90-scene-master
I therefore wanted to edit the zwcfg_xxx.xml file, but I can’t find it in /config, nor in any other folder.

Strangely enough, in my very first attempts, I was able to see the file and edit it. But for some reason, I decided to re-install HA and since then I can’t see the file anymore. I re-installed several times HA but without success, including testing older versions of HA…

I’m running out of ideas. If someone does, I will be grateful …

thanks
