A simple guide on enabling and using sleep/suspend mode on a Proxmox server.
Enabling Sleep Mode
To allow your Proxmox server to enter sleep/suspend mode, open a bash shell and run the following command:
systemctl unmask sleep.target suspend.target hibernate.target hybrid-sleep.target
💡 Note: This command only needs to be run once.
Suspending the Server
Once enabled, you can put your Proxmox server to sleep at any time using:
systemctl suspend
I have integrated this command into my iPhone’s Shortcuts app, allowing me to suspend my server when not in use, reducing power consumption. I can then wake it remotely via Wake-On-LAN, eliminating the need to press the power button physically.
