Need help setting HDD temperature sensors

Configuration
1

Hi,

I’m trying to show my HDD temperature in HA frontend. I have had success with CPU dan motherboard temperature, however HDD temp is just not showing. This is the yaml from sensor.yaml :

  - platform: command_line
    name: CPU Temperature
    command: "cat /sys/class/thermal/thermal_zone2/temp"
    # If errors occur, remove degree symbol below
    unit_of_measurement: "°C"
    value_template: '{{ value | multiply(0.001) | round(1) }}'
  - platform: command_line
    name: Motherboard Temperature
    command: "cat /sys/class/thermal/thermal_zone0/temp"
    # If errors occur, remove degree symbol below
    unit_of_measurement: "°C"
    value_template: '{{ value | multiply(0.001) | round(1) }}'  
  - platform: command_line
    name: HD Temperature
    command: "hddtemp -n /dev/sda"
    # If errors occur, remove degree symbol below
    unit_of_measurement: "°C"

I just copy-pasted from example in the docs. However HDD temp is not showing :

Here is the error from info page :
Command failed: hddtemp -n /dev/sda

I have tried :

  1. Removing the degree symbol (as per comment in the example)
  2. Using full path and even sudo
    sudo /usr/sbin/hddtemp -n /dev/sda

Still same erorr. Anyone please advise me how to get the HDD temp reading?

PS: I’ve installed hddtemp and can get the reading perfectly from command line

Why don’t you just use the hddtemp sensor for that?

And that’s my friend, just how cool this community is… I never thought there’s a component for this, because I was looking for CPU temp at first. Thank you. Everything is good now… :slight_smile:

Anyone using hddtemp with latest Home Assistant (I’m using 0.111.2 with HassOS 4.9) on Raspberry 4? I get following error in logs:

Logger: homeassistant.components.hddtemp.sensor
Source: components/hddtemp/sensor.py:98
Integration: hddtemp (documentation, issues)
First occurred: 12:26:13 (16 occurrences)
Last logged: 12:41:27

HDDTemp is not available at localhost:7634

Commands hddtemp or smartctl seem to be not available in latest OS images.

Thanks, Markus

Hello, I seem to have found the same issue, have you found a solution?

EDIT:
In the case another pool soul comes from Google with the same error: “HDDTemp is not available at localhost:7634”

Here’s what must be done on a Linux host:

First you need to edit the hddtemp config file:
vi /etc/default/hddtemp

If your user lacks write permission you may have to use root:
sudo vi /etc/default/hddtemp

Once the file is open, change:
RUN_DAEMON="false"

To:

RUN_DAEMON="true"

After saving and exit just do this command to reload the service:

service hddtemp restart/start
