hddtemp vs. drivetemp in conky

For the Conky friends 

Recently I was reminded again of my post here about hddtemp and drivetemp because the package hddtemp is removed from bookworm/sid.
I thought the procedure of switching to drivetemp as described by the developer in the apt-listchanges message of  2021-02-02, for you to document.

You don't have to wait until bookworm/sid, because drivetemp greatly simplifies the configuration in the .conkyrc configuration file.

1.
First of all you should know that drivetemp.ko is located in the path
/lib/modules/KERNELVERSION/kernel/drivers/hwmon. If the module is not present on your system, then you still have an older kernel and the procedure is not applicable.

As usual with Linux, you can also find this out in the terminal:

/usr/sbin/modinfo drivetemp
filename: /lib/modules/5.18.16-1-siduction-amd64/kernel/drivers/hwmon/drivetemp.ko
license: GPL
description: Hard drive temperature monitor
author: Guenter Roeck <linus@roeck-us.net>
depends:        
retpoline:      Y
intree:         Y
name: drivetemp
vermagic: 5.18.16-1-siduction-amd64 SMP preempt mod_unload modversions  

2. to apply the module now

sudo mkdir /etc/modules-load.d/

(if the VZ modules-load.d already exists, this step is omitted)

3.

echo drivetemp | sudo tee /etc/modules-load.d/drivetemp.conf

4.
so that the module is always loaded automatically, enter as root in the file /etc/modules
drivetemp
If there are already other modules in this file, please note that each module has a new line!

5. managed
Reboot or load the module with modprobe -a (I recommend reboot).

6.
after reboot the command tells me

for m in /sys/class/hwmon/* ; do echo -n "$m = " ; cat $m/name ; done
/sys/class/hwmon/hwmon0 = acpitz
/sys/class/hwmon/hwmon1 = BAT0
/sys/class/hwmon/hwmon2 = drivetemp
/sys/class/hwmon/hwmon3 = AC
/sys/class/hwmon/hwmon4 = coretemp
/sys/class/hwmon/hwmon5 = thinkpad

where drivetemp is displayed in hwmon.
In the configuration file of Conky you only have to add

${hwmon 2 temp 1}

That's it.

Re: hddtemp vs. drivetemp in conky

Won't work here.  Do not know why. /etc/modules is correct, as well as /etc/modules-load.d  Rebooted, but no drivetemp when checking /sys/class/hwmon. Something else needed maybe?

  /usr/sbin/modinfo drivetemp
filename:       /lib/modules/5.15.6.1-march/kernel/drivers/hwmon/drivetemp.ko
license:        GPL
description:    Hard drive temperature monitor
author:         Guenter Roeck <linus@roeck-us.net>
depends:        
retpoline:      Y
intree:         Y
name:           drivetemp
vermagic:       5.15.6.1-march SMP preempt mod_unload modversions

sleekmason@ai:~$ for m in /sys/class/hwmon/* ; do echo -n "$m = " ; cat $m/name ; done
/sys/class/hwmon/hwmon0 = nvme
/sys/class/hwmon/hwmon1 = acpitz
/sys/class/hwmon/hwmon2 = BAT0
/sys/class/hwmon/hwmon3 = AC
/sys/class/hwmon/hwmon4 = dell_smm
/sys/class/hwmon/hwmon5 = coretemp

# /etc/modules: kernel modules to load at boot time.

Re: hddtemp vs. drivetemp in conky

I assume your nvme drive does not support the drivetemp driver.

Search under /sys/class/hwmon/hwmon0
There is probably the temperature sensor for your drive.   

Edit:
Surely you won't get any output:

sudo smartctl -A /dev/sda

but with

sudo smartctl -A /dev/nvme0

This is interesting stuff. All new to me.

I did not have smartmontools, so installed that to learn more through smartctl.  Thanks for the info!

Re: hddtemp vs. drivetemp in conky

Revisited this post and realized I have a whole bunch of conkys that need converting.

Thank you unklar

Since you have at least 4 times as many conky's, I recommend, don't do it until you realize while playing around with one of these conky's, there is something wrong
I, as an O.F.C., speak from experience....

Re: hddtemp vs. drivetemp in conky

I have my "test.conky" I tested it and checked things out with old ways of getting the info.
Seems good so far.  Not going to go through all my conkys.
After all, I need time to eat and drink coffee 

CHIMO my friend.
