Nexia: Expose RoomIQ sensors as HA sensor entities

It would be helpful to have Nexia RoomIQ sensors available as HA sensor entities. My main interest is for monitoring of the Z-Wave sensor battery levels, but it would also allow for tracking temperature and humidity on a per-sensor basis.

The information is already available to HA as shown in the following snipped from the diagnostics JSON output.

          {
            "name": "room_iq_sensors",
            "sensors": [
              {

                  "name": "room_iq_onboard",
                  "modifiers": []
                },
                "type": "thermostat",
                "serial_number": "NativeIDTUniqueID",

                "name": "Master Bedroom",
                "icon": {
                  "name": "room_iq_wireless",
                  "modifiers": []
                },
                "type": "930",
                "serial_number": "<redacted>",

                "humidity": 47,
                "humidity_valid": true,
                "has_online": true,
                "connected": true,
                "has_battery": true,
                "battery_level": 38,
                "battery_low": false,
                "battery_valid": true
              }
            ],
            "should_show": true,
            "actions": {
              "request_current_state": {
                "href": "https://www.mynexia.com/mobile/xxl_zones/<redacted>/request_current_sensor_state"
              },
              "update_active_sensors": {
                "method": "POST",
                "href": "https://www.mynexia.com/mobile/xxl_zones/<redacted>/update_active_sensors"
              }
            }
          },

I would have to agree on the battery info on any remote sensor provide by any thermostat manufacturer. Mine is from the ecobee line of smart thermostats

Did anyone ever figure out how to do this?
