Stop guessing if your UPS is protecting your setup

The Problem

Your UPS may be quietly handling outages, low battery events, or runtime issues, but the warning signs are often buried on a server, NAS, or dashboard you rarely check.

The Solution

UPSLink brings UPS status, alerts, runtime, battery health, and widgets directly to your Android phone so you can react before power problems become server problems.
