Websocket API and Z-Wave?

Configuration Z-Wave
1

I’m writing a script to automatically provision certain parts of Home Assistant. My goal is to be able to reproduce what I can do manually via the UI and zwave > Config but with a script using websocket (and rest-api if not everything is available via the websocket-api).

The problems I have are the following:

  1. Get the parent zwave-entity for a child entity.
    All zwave-entities that belong to the same device seems to have the same device_id EXCEPT the actual zwave device where the device_id is null:
{
    "config_entry_id": null,
    "device_id": null,
    "disabled_by": null,
    "entity_id": "zwave.v0_shop_motion",
    "name": "Verkstaden r\u00f6relse",
    "platform": "zwave"
  }, {
    "config_entry_id": "7d77955f6c0b4d07aa786bc8125e79fd",
    "device_id": "de578d219b024882ae4981e31ab9b4eb",
    "disabled_by": null,
    "entity_id": "sensor.v0_shop_motion_temperature",
    "name": "Verkstaden Eye temperatur",
    "platform": "zwave"
  }
  1. Get the type of sensor of a child entity.
    When I look at the rest-call made by the web ui it calls /api/zwave/values/<Node ID> which have the information I look for in the label key. But from the websocket API I can’t find the Node ID to use in the REST-api, and I can’t see a way to associate the child entity results in the websocket result with the child entities in the rest-api call
"72057594479132690": {
        "index": 1,
        "instance": 1,
        "label": "Temperature",
        "poll_intensity": 0
    }

I do not want to rely on the default entity_id or name for detecting type of child entity but to be sure I wan’t to use whats in the zwave configuration used to populate those fields (I can’t be sure that the entity_id or name haven’t been changed since the adding of the device and me running the script)
