I setup this script a few weeks back but today i also installed my smtp server on proxmox and i constantly get emails from crondaemon with:

EDIT: I FOUND THE SOLUTION: (i will leave my comment here in case anyone else has this problem)
First you need to open the crontab
crontab -e

Then you add >/dev/null 2>&1 behind the task
*/1 * * * * /root/ha_post_temp.sh >/dev/null 2>&1

Then save it(ctrl+X/yes) and restart it again
systemctl restart cron.service

Hi!

My output in manual mode:

How to modify this script to get:

• CPU Temp
• Fan RPM
• Battery voltage
• Other available info (optional, I willtry to manage myself)

Thank you in advance.
