CPU Temperature of VM host

Configuration
1

Hello!

I’m trying to get the CPU Temperature of my VM Host in Home Assistant.
This command I came up with works perfectly when executing within the HA Terminal:
ssh -o LogLevel=QUIET [email protected] -i /config/.ssh/id_rsa -t "sensors | grep -i package | grep -o 'Package id 0: +[^;][^;]' | grep -o '[0-9][0-9]'"
however when I add it to the config like this it’s not working anymore:

sensor:
  - platform: command_line
    name: CPUTemp
    command : "ssh -o LogLevel=QUIET [email protected] -i /config/.ssh/id_rsa -t \"sensors | grep -i package | grep -o 'Package id 0:  +[^;][^;]' | grep -o '[0-9][0-9]' \" "

Would you consider using something like Glances on the host, and then using the integration to get the values? This will give you CPU temps plus much more. Alternatively, if your host is running Proxmox, there’s a HACS integration that provides this plus more.

I’m using this to get the CPU temperature from my VM host (Proxmox):

command_line:
  - sensor:
      name: temperature_cpu
      command: 'ssh -i /config/.ssh/id_rsa -o StrictHostKeyChecking=no -q [email protected] cat /sys/class/thermal/thermal_zone0/temp'
      value_template: "{{ value | int / 1000 }}"
      unit_of_measurement: "°C"
      scan_interval: 600

Thanks for your script. When I add that to my “/homeassistant/configuration.yaml” and restart nothing happens, I don’t get any messages in “System/Logs” but also no sensor :frowning:

command_line:
  - sensor:
      name: temperature_cpu
      command: 'ssh -i /config/.ssh/id_rsa -o StrictHostKeyChecking=no -q [email protected] cat /sys/class/thermal/thermal_zone0/temp'
      value_template: "{{ value | multiply(0.001) | round(1) }}"
      unit_of_measurement: "°C"
      scan_interval: 300

Again, runing the comand in the HASOS Terminal works like expected…

Update: Restarting 10x somehow resolved it - many thanks!
