Monitor remote PI CPU temp

Configuration
2

If home assistant is running on the Raspberry Pi, I use this:

sensor:

  - platform: command_line
    name: CPU Temp
    command: "/bin/cat /sys/class/thermal/thermal_zone0/temp"
    unit_of_measurement: "ºC"
    value_template: '{{ value | multiply(0.001) }}'

  - platform: systemmonitor
    resources:
    - type: disk_use_percent
      arg: /
    - type: memory_free
    - type: memory_use_percent
    - type: processor_use
    - type: since_last_boot
    #- type: network_in
    #  arg: eth0
    #- type: network_out
    #  arg: eth0

I put this in a file `packages/dev_pi.yaml" or similar, and include the package from the main configuration.

Then I havea group:

dev_pi:
  name: Pi
  entities:
    - sensor.cpu_use
    - sensor.cpu_temp
    - sensor.disk_use_
    #- sensor.disk_use_home
    - sensor.ram_free
    - sensor.ram_use_percent
    - sensor.since_last_boot
