Install

Currently, it only supports linux system

(use-package emacs-cpu-temperature
  :straight (:host github :repo "zhenhua-wang/emacs-cpu-temperature")
  :init
  (setq cpu-temperature-update-interval 1
        cpu-temperature-method 'thermal-zone
        cpu-temperature-thermal-zone-type "x86_pkg_temp"
        cpu-temperature-thermal-zone-path "/sys/class/thermal/")
  :config
  (cpu-temperature-mode 1))

Update

2024-05-19 Add support for HWMON

Reading temperature from HWMON is supported and the default temperature to monitor is Composite, which can be customized.

Usage

To show it on mode-line or tab-bar, you can simple append the variable cpu-temperature-string to global-mode-string.

(add-to-list 'global-mode-string 'cpu-temperature-string t)

If you want to change config on the fly, make sure to re-run (cpu-temperature-set-path) to take effect.
