️ Is your Home Assistant setup quietly breaking behind the scenes?
Meet HACSIntegration Watchman—a must-have integration that scans your system for broken links, missing entities, and misbehaving automations. (A good addition to SystemMonitor)
In this step-by-step guide, I’ll show you how to:
✔️ Install HACS Watchman
✔️ Create a clean, useful dashboard card for system issues
✔️ Write a script that auto-checks your setup every day
Why Watchman? Because surprises are fun—just not in your smart home.
Have you used Watchman before? Got a dashboard trick to share?
