What are you trying to do exactly? If you have config_path in your configuration.yaml file, then that’s the path it is using. If you go through my message history you can find a python command to display the autodetect path.
You should be wary of topics that are 7 months old, this information in this topic is outdated now. If you want to use config files from OpenZWave you need to use the 1.4 branch. Currently there are only a handful of devices that exist in OpenZWave 1.4 but are missing from HA. So using config path is unnecessary unless you need to make manual changes, or have one of those missing devices.
