Re-download the firmware and reinstall. There is a problem with your system.

Non-root users need to add sudo when executing system operation commands

Execute these 3 commands separately to see which one can be used

sensors | grep -Eo '\+[0-9]+.+C' | sed ':a;N;$!ba;s/\n/ /g;s/+//g'


awk '{ printf("%.1f °C", $0 / 1000) }' /sys/class/hwmon/hwmon0/temp1_input

Did you delete the sudo privileges of the root user?

User permissions are incorrect, many operations are invalid

add your user to sudo group

sudo -i

sudo usermod -aG sudo root
sudo usermod -aG sudo klipper


sudo apt-get update
sudo apt-get install -y lm-sensors

sensors | grep -Eo '\+[0-9]+.+C' | sed ':a;N;$!ba;s/\n/ /g;s/+//g'

kobzzon · 2022-11-13T07:58:59Z

sensors | grep -Eo '+[0-9]+.+C' | sed ':a;N;$!ba;s/\n/ /g;s/+//g'

Regardless of the temperature issue.
Your basic user permissions are wrong. Unable to use Armbian system normally.

The temperature is in this file. Find the temperature viewing method that suits your box and modify this place:
/usr/lib/armbian/armbian-allwinner-battery

Call display in this file:

sudo vi /usr/lib/armbian/armbian-allwinner-battery

#read raw_temp </etc/armbianmonitor/datasources/soctemp 2>/dev/null
raw_temp="$(sensors 2>/dev/null | grep -Eo '\+[0-9]+' | awk '{print $1}' | head -n1 | sed -e 's|+||')"

Referring to the above figure, comment out the original line 13 and add a new temperature acquisition method
After saving, log in again with ssh to see the temperature display

Or modify the algorithm on line 19. Count numbers to the correct number of digits.

Use ssh to log in to armbian, copy and paste each line of command separately, and fix the temperature display error.

temp_file="/usr/lib/armbian/armbian-allwinner-battery"
insert_line="$(cat ${temp_file} | grep -n 'CPU_TEMP_OFFSET' | awk -F':' '{print $1}')"
sed -i "${insert_line}i\        [[ \"\$(echo \${board_temp} | awk -F'.' '{print \$1}' | wc -c)\" -gt \"3\" ]] && board_temp=\${board_temp:0:2}" ${temp_file}

It's works! Great! Many thx!!!

ophub · 2022-11-22T09:37:08Z

ok

kobzzon · 2022-11-22T10:58:55Z

ok

But in Fluidd displaying wrong

ophub · 2022-11-22T11:38:58Z

I don't know about other software

kobzzon · 2022-11-22T12:03:47Z

I don't know about other software

And didn't work any webcams

kobzzon · 2022-11-22T12:26:04Z

I don't know about other software

From Fluidd issue:
"Assuming you are using a sensor_type: temperature_host in your Klipper printer.cfg, you will most likely have to override the sensor_path as Klipper by default will use /sys/class/thermal/thermal_zone0/temp but that doesn't seem to be available in your system.

You can confirm by SSH'ing and then cat /sys/class/thermal/thermal_zone0/temp and checking the result"

How can i do this?

ophub · 2022-11-22T12:39:00Z

For the use of third-party software, go to the corresponding website for consultation, I don’t know how to use it
