# Run a loop
client.loop()

• Adapt crontab to run each 30 seconds

* * * * * python /root/work/cpu_info.py
* * * * * ( sleep 30 ; python /root/work/cpu_info.py )

• Add the following to configuration.yaml

mqtt:
  sensor:
    - name: cpu temperature
      state_topic: "homeassistant/sensor/pve_system/cpu1"
      unit_of_measurement: "°C"
