I have added a new SenseBender NodeManger which is visible in the dev-states screen. However one of the children sensors is not showing in the dev-states screen in HA . Specifically the door sensor which is child sensor #3. Below is a copy and paste from the dev-states screen.

I'm successfully running a number of other NodeManager SenseBender nodes on HA with just temp and humidity.

The mysensors.json file appears to be showing the correct number of children sensors, including sensor #3 which is the door sensor:

"113": {
    "sensor_id": 113,
    "children": {
      "1": {
        "id": 1,
        "type": 6,
        "description": "",
        "values": {
          "0": "24.99"
        }
      },
      "2": {
        "id": 2,
        "type": 7,
        "description": "",
        "values": {
          "1": "69.01"
        }
      },
      "3": {
        "id": 3,
        "type": 23,
        "description": "",
        "values": {
          "16": "1"
        }
      },
      "200": {
        "id": 200,
        "type": 23,
        "description": "",
        "values": {
          "48": "SLEEPING"
        }
      },
      "201": {
        "id": 201,
        "type": 30,
        "description": "",
        "values": {
          "38": "3.34"
        }
      }
    },

I know that the door sensor is working as child sensor #200 shows the change to the wake / sleeping state when the NodeManager wakes up from the door sensor interrupt. Also, I can see that the NodeManager is sending the message in the serial console on change to the door sensor,

Any thoughts as to why child sensor #3 is not showing in HA?

Thanks,
Simon
