Missing rtl_433 MQTT Entities

Configuration
1

I’m stumped. I have rtl_433 running on my linux desktop sending messages to broker, HA subscribed to topic set up here:

# /config/mqtt.yaml included in /config/configuration.yaml like this:
# mqtt: !include mqtt.yaml
  sensor:
    - state_topic: "rtl_433/Oregon-THGR122N/7"
      name: "Front Porch Temp"
      unique_id: "oregon_122n_temp"
      unit_of_measurement: '°C'
      value_template: "{{ value_json.temperature_C }}"
      device_class: temperature

    - state_topic: "rtl_433/Oregon-THGR122N/7"
      name: "Front Porch Humidity"
      unique_id: "oregon_122n_humidity"
      unit_of_measurement: '%'
      value_template: "{{ value_json.humidity }}"
      device_class: humidity

    - state_topic: "rtl_433/Oregon-v1/4"
      name: "Oregon_v1"
      unique_id: "oregon_v1_4_temp"
      unit_of_measurement: '°C'
      value_template: "{{ value_json.temperature_C }}"
      device_class: temperature

    - state_topic: "rtl_433/Acurite-609TXC/20"
      name: "Crawlspace Acurite Temp"
      unique_id: "acurite_609txc_temp"
      unit_of_measurement: '°C'
      value_template: "{{ value_json.temperature_C }}"
      device_class: temperature

    - state_topic: "rtl_433/Acurite-609TXC/20"
      name: "Crawlspace Acurite Humidity"
      unique_id: "acurite_609txc_humidity"
      unit_of_measurement: '%'
      value_template: "{{ value_json.humidity }}"
      device_class: humidity

…

There are a dozen or so various other sensors defined here as well. All work just fine except the Oregon-THGR122N.

Looking at the logs, HA is subscribed and receiving messages:

2022-06-16 10:59:14 DEBUG (MainThread) [homeassistant.components.mqtt.client] Subscribing to rtl_433/Oregon-THGR122N/7, mid: 5

But the entities do not show up in HA. There are no ‘oregon_122n_xxxx’ entities. All other sensors work just fine.

Running HA OS on a RaspberryPi 4.

Anyone have a clue as to what I’m missing here?

Seems this is an ‘operator headspace’ issue. Got it in my head that the unique_id would be used, not the ‘name’. This device just happens to be the one and only place the name and the unique_id differ enough for it not to come up in a seach. Duh!
