lm_sensors is a free and open-source application that provides tools and drivers for monitoring temperatures, voltage, and fans. This document explains how to install, configure, and use lm_sensors.
# emerge lm_sensors
lm_sensors service needs configuration in the
/etc/conf.d/lm_sensors file, which doesn't exists by default and can be generated by running the
This tool will try to identify the kernel's modules needed by sensors and then place them into configuration file
/etc/conf.d/lm_sensors to be loaded/unloaded when the service starts/stops.
When some of these modules are loaded (e.g. from
/etc/conf.d/modules or manually),
sensors-detect can skip adding them into configuration file and service will not start them with next system (re)start.
To enable service at boot time, add the service into openrc runlevel:
# rc-update add lm_sensors default
