My smart home was a mess until I gave it a brain

A personal account of how Home Assistant resolved a fragmented smart home setup. The author was juggling four separate apps, dealing with unsynchronized routines causing random device triggers, and constant interruptions. By installing Home Assistant on an existing NAS/old PC, all devices were unified into a single local dashboard independent of external servers. A simple presence-based automation now handles lights, plugs, and sensors automatically based on whether the owner is home or away, eliminating repetitive manual decisions and reducing mental load.
