最近ha连续报错
Logger: homeassistant.components.command_line
Source: components/command_line/__init__.py:48

Command failed (with return code 1): cat /sys/class/thermal/thermal_zone0/temp
不太懂啥意思，通过英文翻译，可能是命令行错误，但不知道怎么进一步查找问题，麻烦坛子大佬指明解决方案
下面是yaml文件中的代码

#　CPU 温度
- platform: command_line
  name: CPU Temperature
  command: "cat /sys/class/thermal/thermal_zone0/temp"
  unit_of_measurement: "°C"
  value_template: '{{ value | multiply(0.001) | round(1) }}'

代码是抄作业抄的，是不是代码有问题？
