Use:
chmod +x ha_post_temp.sh

Create a cron job to run the script:
Execute the command crontab -e.

Add to the last line (in this configuration, the sensors will be updated every minute):
*/1 * * * * /usr/ha_post_temp.sh

or

Add to the last line (in this configuration, the sensors will be updated every 10 minutes):
*/10 * * * * /usr/ha_post_temp.sh

Restart the cron service:
sudo systemctl restart cron.service
or
sudo systemctl restart crond.service

Check the cron service
sudo systemctl status cron.service

PS:
device info not working

Hi, I adjusted my devices and the commands work manually ( like when i do sensors | grep 'Tctl:' it gives me a Temp output) but in the sript returns 404: Not found

This is my Script: `#!/bin/bash

Function to send data to Home Assistant

Send CPU package temperature

cpu_temp=$(sensors | grep 'Tctl:' | awk '{print $4}' | sed 's/+//;s/°C//')
send_to_ha "sensor.${srv_name}_cpu_temperature" "${cpu_temp}" "CPU Package Temperature" "mdi:cpu-64-bit" "${srv_name}_cpu_temp"

Send Chipset temperature (adjust device if necessary)

chipset_temp=$(sensors | grep 'temp1:' | awk '{print $2}' | sed 's/+//;s/°C//')

if [[ $chipset_temp != "" ]]; then
send_to_ha "sensor.${srv_name}_chipset_temperature" "${chipset_temp}" "Chipset Temperature" "mdi:chip" "${srv_name}_chipset_temp"
fi

Send NVMe/SSD composite temperature (adjust device if necessary)

nvme_temp=$(sensors | grep 'Composite' | head -1 | awk '{print $2}' | sed 's/+//;s/°C//')
if [[ $nvme_temp != "" ]]; then
send_to_ha "sensor.${srv_name}_nvme_temperature" "${nvme_temp}" "NVMe/SSD Temperature" "mdi:harddisk" "${srv_name}_nvme_temp"
fi

Send GPU temperature (adjust device if necessary)

gpu_temp=$(sensors | grep 'edge:' | awk '{print $2}' | sed 's/+//;s/°C//')
if [[ $gpu_temp != "" ]]; then
send_to_ha "sensor.${srv_name}_gpu_temperature" "${gpu_temp}" "GPU Temperature" "mdi:gpu" "${srv_name}_gpu_temp"
fi`

and when I run it after I made it executable I get 404: Not Found404: Not Found404: Not Found404: Not Found

Hi. I need some help ... really, a lot of :(

The output of sensors in my OMV in the CM3588 is "strange":

npu_thermal-virtual-0
Adapter: Virtual device
temp1:        +42.5°C  (crit = +115.0°C)

test_battery-virtual-0

bigcore0_thermal-virtual-0

How do I have to modify the previous script to be able to "extract" the temp1 from the bigcore1_thermal-virtual-0 temperature, for example?

I found the solution with the help of Microsoft copilot :)

cpu_temp=$(sensors | awk '/bigcore1_thermal-virtual-0/{getline; getline; print $2}' | awk -F'[+°C]' '{print $2}')

Thank you!
