"KCS" v2.2.2 firmware BIN file download

[Philadam]

I have both a kc868-a16 and kc868-am. Sensors on the a16 work in Home Assistant, but the sensors on the AM don't. Both have MQTT enabled.
Sensor configuration in configuration.yaml are:

mqtt:

  sensor:
 
    - name: 'a16-kcs-temp-sensor-1'
      unique_id: a16-kcs-temp-sensor-1
      state_topic: 'KC868_A16/XXXXXXXXXXXX/STATE'
      suggested_display_precision: 100
      unit_of_measurement: "°F"
      value_template: '{{ value_json.sensor1.temperature }}'
     
    - name: 'a16-kcs-temp-sensor-2'
      unique_id: a16-kcs-temp-sensor-2
      state_topic: 'KC868_A16/XXXXXXXXXXXX/STATE'
      suggested_display_precision: 100
      unit_of_measurement: "°F"
      value_template: '{{ value_json.sensor2.temperature }}'

    - name: 'a16-kcs-temp-sensor-3'
      unique_id: a16-kcs-temp-sensor-3
      state_topic: 'KC868_A16/XXXXXXXXXXXX/STATE'
      suggested_display_precision: 100
      unit_of_measurement: "°F"
      value_template: '{{ value_json.sensor3.temperature }}'

    - name: 'am-kcs-temp-sensor-1'
      unique_id: am-kcs-temp-sensor-1
      state_topic: 'KC868_AM/XXXXXXXXXXXX/STATE'
      suggested_display_precision: 100
      unit_of_measurement: "°F"
      value_template: '{{ value_json.sensor1.temperature }}'
     
    - name: 'am-kcs-temp-sensor-2'
      unique_id: am-kcs-temp-sensor-2
      state_topic: 'KC868_AM/ XXXXXXXXXXXX /STATE'
      suggested_display_precision: 100
      unit_of_measurement: "°F"
      value_template: '{{ value_json.sensor2.temperature }}'
     
    - name: 'am-kcs-temp-sensor-3'
      unique_id: am-kcs-temp-sensor-3
      state_topic: 'KC868_AM/ XXXXXXXXXXXX /STATE'
      suggested_display_precision: 100
      unit_of_measurement: "°F"
      value_template: '{{ value_json.sensor3.temperature }}'
     
    - name: 'am-kcs-temp-sensor-4'
      unique_id: am-kcs-temp-sensor-4
      state_topic: 'KC868_AM/ XXXXXXXXXXXX /STATE'
      suggested_display_precision: 100
      unit_of_measurement: "°F"
      value_template: '{{ value_json.sensor4.temperature }}'

Any ideas on why the sensors in the kc868-am are not showing up in the HA view using MQTT.
