This tiny Raspberry Pi Zero W quietly became the control center of my homelab. It’s tucked behind my setup (yes, the cable mess is real ), but it’s doing all the important work in the background.
I’ve set it up to send Wake-on-LAN packets to both my servers (manager node / worker node), so everything powers up automatically without me touching anything. The real magic is during power outages — I wrote a simple script that detects LAN power loss and safely shuts down the systems before anything gets corrupted.
When electricity comes back, the Pi boots automatically, runs the script again, and wakes both machines back up. Completely hands-free recovery.
No fancy hardware, no expensive controllers — just a low-power Pi Zero W doing reliable automation 24/7. It barely consumes any electricity but keeps the entire setup in sync.
This is probably one of the most satisfying upgrades I’ve done in my homelab. Small, cheap, and insanely useful.
