Managing Files in HomeAssistant OS

I am trying to locate the directory structure in HomeAssistant OS that would be analogous to “/usr/share/hassio/addons” in HomeAssistant Supervised. In addition to locating it, I need to have write permission. Thank you.

I think it is whatever directory is mapped to /data in docker.

I don’t know what “mapped to /data in docker” means.

Someone created a straightforward solution to be able to use more than one Z-Wave controller in HA:
https://community.home-assistant.io/t/cloning-the-z-wave-js-to-mqtt-add-on-to-run-multiple-z-wave-networks/415863

It was created for HA Supervised. I am trying to adapt it for HA OS. Perhaps this is not possible. I don’t know.

I have been searching for the corresponding directory (using both Terminal and Studio Code Server).

What addons do you presently have?
