MQTT integration issues

Configuration
1

I have an ESP32 sensor with a DHT11 and Barometer sensor publishing data into topics on my Raspberry Pi running the broker. I’ve check my yaml below through online validation and no issues. I’m running the latest version of HA 12.5.

I cannot get the MQTT to find the entities so I can use them in cards.

I test listen to topics on the broker integration and I get the messages.

It used to work and now I can’t figure it out.

mqtt:
  sensor:
    - name: "Temperature"
      platform: "sensor"
      state_topic: "homeassistant/publish/temperature"
      unique_id: "Temp"
      unit_of_measurement: "F"
      value_template: "{{ value | int }}"
      state_class: "total"

    - name: "ESP32 Temp"
      state_topic: "esp32/internaltemp"
      unique_id: "ESP32 Temp"
      unit_of_measurement: "F"
      value_template: "{{ value | int }}"
      state_class: "total"

    - name: "Humidity"
      state_topic: "homeassistant/publish/humidity"
      unique_id: "Humidity_"
      unit_of_measurement: "%"
      value_template: "{{ value | int }}"

Hello stevenstaley,
Welcome to the HA Forum.

Troubleshooting MQTT? MQTT-Explorer can help you be successful!
If you have Add-ons available, try adding this Add-on repository to your Add-on list. GitHub - GollumDom/addon-repository.
