System Sensors: RPI CPU and Temperature

My Home Assistant is running on a Raspberry PI4, that is working quite fine for my purposes, but I want to monitory the CPU usage and System Temperature to avoid any hardware failure.

Define new Sensors

• Copy and paste following come to your Configuration.yaml file sensor section (create it if doesn’t already exists). Full system sensors list, here
• Reboot the system

sensor:
  - platform: systemmonitor
    resources:
      - type: memory_free
      - type: memory_use
      - type: memory_use_percent
      - type: swap_use_percent
      - type: swap_use
      - type: swap_free
      - type: processor_use
      - type: processor_temperature
      - type: disk_use_percent
        arg: /config
      - type: disk_free
