If you have SSH access you can update the files in the python_openzwave ozw_config directory. The path on my server is /srv/homeassistant/lib/python3.6/site-packages/python_openzwave/ozw_config/. You will likely have to exclude and then re-include your device in order for it to pick up the new configuration. If you are able to do that and everything works as you expect I would recommend you submit a pull request to the openzwave project, more information can be found here https://github.com/OpenZWave/open-zwave/wiki/Adding-Devices.
