Setting up lm sensors

This document is a short note on how to set up lm_sensors in Alpine.

Install the neccessary packages. You will need perl to run the sensors-detect script.

 apk_add lm_sensors perl

Load the i2c-dev module:

 echo i2c-dev >> /etc/modules
 modprobe i2c-dev

Note: If you already know the name of the sensor module, you can modprobe it now, and skip the sensors-detect and perl install.

Run sensors detect:

 sensors-detect

On the question to scan ISA bus and Super I/O sensors, select "no". Grsec will not allow you to access /proc/port. On all other questions select the default.

You will not need perl anymore. Remove it before you forget.

 apk_delete perl

Make services start during next reboot.

 rc_add -k lm_sensors sensord

Start services:

 /etc/init.d/lm_sensors start
 /etc/init.d/sensord start

Save config using lbu commit.
