The original hddtemp is not maintained far too long. Due to that it was removed from the official repositories of Ubuntu (since 22.04) and Debian (since 12). This tool can be used instead to print the temps:
> sudo hddtemp-lt /dev/sda WDC WD10EFRX-68FYTN0 28 /dev/nvme0 Samsung SSD 950 PRO 256GB 40
smartctl
fromsmartmontools
package- NVMe support:
smartctl
v6.5+
- NVMe support:
hddtemp-lt [options] [disk1 ..]
Without any disk arguments, show temperature for all sd and nvme disks.
-h, --help
- Show usage
-q
- Suppress warnings
-V, --version
- Show version
--classic
- Replicate output format of the original hddtemp
--classic-tcp
- Replicate TCP daemon output format of the original hddtemp
--hint path
- Provide a file containing
smartctl --scan-open
output as a hint for device types (-d
option value forsmartctl
) -u, --units C|F
- Use Celsius (default) or Fahrenheit scale
Sometimes you could see NA
(Not Available) printed instead of info about
some disk. It could mean smartctl
failed to auto-detect the connection
type. In the case, first scan your devices (it is important to use
--scan-open
, not just --scan
):
sudo smartctl --scan-open | tee smart-scan.txt
Next, feed it to the --hint
option:
sudo hddtemp-lt --hint smart-scan.txt
Notice: It is important to keep the hint file in sync with connected disks.
By default, output is aligned into columns. Device models can contain spaces like WDC WD10EFRX-68FYTN0 or Samsung SSD 950 PRO 256GB so fields are separated by at least two spaces.
When --classic
is applied:
- output is not aligned, fields are separated by a colon followed by a space
- scale marker is added
Sample classic output:
> sudo hddtemp-lt --classic /dev/sda: WDC WD10EFRX-68FYTN0: 28°C /dev/nvme0: Samsung SSD 950 PRO 256GB: 40°C
When --classic-tcp
is applied:
- output is not aligned, fields are pipe separated
- there are no newlines
- units marker is a separate field
Sample classic-tcp output:
> sudo hddtemp-lt --classic-tcp |/dev/sda|WDC WD10EFRX-68FYTN0|28|C||/dev/nvme0|Samsung SSD 950 PRO 256GB|40|C|
Under systemd/ you can find basic systemd unit files to run a hddtemp-compatible
tcp server on port 7634
.
Notice: hddtemp-lt@.service
assumes the tool is installed into
/opt/hddtemp
.
Fetch the archive either from releases or from the development branch, extract
it and put hddtemp-lt
under /usr/local/bin/
. In case you downloaded the
script alone from github by a raw link, be sure to manually make it executable.
No serial numbers, no time:
sudo smartctl -q noserial -i -A -l scttempsts /dev/sda | grep -v 'Local Time is'
