Sensor for latest docker image versions

Thanks, where I fail is with defining MQTT sensors in HASS, I receive the message but can’t integrate it.

These are my env variables, messages are sent and I can see them in mqtt queue, but not in homeassistant sensor.

      env:
        - name: TZ
          value: "Europe/Paris"
        - name: LOG_LEVEL
          value: "info"
        - name: LOG_JSON
          value: "false"
        - name: DIUN_WATCH_WORKERS
          value: "20"
        - name: DIUN_WATCH_SCHEDULE
          value: "0 */6 * * *"
        - name: DIUN_PROVIDERS_KUBERNETES
          value: "true"
        - name: DIUN_PROVIDERS_KUBERNETES_WATCHBYDEFAULT
          value: "true"
        - name: DIUN_NOTIF_MQTT_SCHEME
          value: "mqtt"

          value: "user"
        - name: DIUN_NOTIF_MQTT_PASSWORD
          value: "password"
        - name: DIUN_NOTIF_MQTT_CLIENT
