Sudo permission with no password

[ale_fedeli]

Hi, I'm trying to create a user with sudo permission for a few commands (reboot and shutdown) but with no password required, so that my Raspberry Pi (that's running Home Assistant) can remotely shut down my Nas when my Ups battery ( which powers both devices) is low. I've tried to modify the Sudoers file, but when I reboot the machine, all the changes that I've made get lost.

Can someone help me?

Create the user in the GUI and add it to the wheel group.

You could also set up NUT on your Pi and have the NAS UPS service connect to that and manage it from there instead.

If you have your UPS connected to your RPi via USB, you can install NUT and set it up as a UPS Master.
Then set up your NAS as a UPS Slave (any another clients for that matter), which will monitor the UPS status and shutdown by itself.

Works automagically!

Thank you for the advice, I'm gonna try to set up Nut in TrueNas. I hope it works.
