Replaced UPS batteries but runtime dropped? The APC remembers old capacity. Instead of shutting down my homelab and fumbling with cables, I calibrated the UPS remotely via Home Assistant's NUT addon using raw netcat commands. Runtime nearly doubled. Zero cables touched.
"SMART status: PASSED" - the biggest lie in storage monitoring. My WD Red drive was dying with 69 errors at LBA=0, clicking mechanically, yet SMART said everything was fine. A 48-hour battle with silent hardware failure that nearly cost me 4.5TB of data. ZFS saved me, but barely.
The improvement is staggering! We went from ~5-6 milliseconds accuracy with internet sources to just 82 microseconds with local GPS. That's over 60 times more accurate! This is stratum 1 time accuracy in my homelab!
Upgrading Frigate NVR with a Google Coral TPU delivered 4× faster detection, 10× lower CPU usage, and reduced power by 50W. This essential homelab upgrade pays for itself in under 10 months while dramatically improving performance.
Transform your homelab with a custom validated domain using Nginx Proxy Manager, Cloudflare, and wildcard SSL. Access services through clean, secure URLs instead of IP addresses and ports.
Discover how I diagnosed mysterious VM failures in my homelab by accessing my LSI RAID controller, identified cascading disk failures across multiple volumes, and developed a monitoring script to prevent future storage catastrophes.
