Recently described hddtemp application does not contain every possible hard drive in its database. I’ll be honest here, its development stopped many years ago, but it is still very useful, so I will shortly describe how to add new hard drive to the database.
I have acquired Intel 530 Series SSD which is missing in the application database.
$ sudo hddtemp /dev/sda WARNING: Drive /dev/sda doesn't seem to have a temperature sensor. WARNING: This doesn't mean it hasn't got one. WARNING: If you are sure it has one, please contact me (hddtemp@guzu.net). WARNING: See --help, --debug and --drivebase options. /dev/sda: INTEL SSDSC2BW180A4: no sensor
Notice hard drive name
INTEL SSDSC2BW180A4 as it will be needed later.Use smartcl utility from smartmontools package to identify attribute id that contains temperature.
$ sudo smartctl --all /dev/sda

Notice that
attribute id 190 contains airflow temperature (Celsius).Verify that hddtemp value for attribute/field id 190 is the same.

Append hard drive to the /etc/hddtemp.db database using gathered data.
$ cat << EOF | sudo tee -a /etc/hddtemp.db "INTEL SSDMCEAW080A4" 190 C "INTEL SSD 530" EOF
Now you can use hddtemp application and it will print correct temperature.
# hddtemp /dev/sda /dev/sda: INTEL SSDMCEAW080A4: 44°C
