After driving halfway to work only to turn back and check (more than once, I’ll admit), I decided it was time for a solution. I wanted something more reliable than my memory and more integrated than a basic standalone smart opener. In this tutorial, I’ll show you how I used a cheap ESP32 board and some reed switches—the same type of sensor in door/window alarms—to create a smart garage door monitor that integrates seamlessly with Home Assistant.
