Back when my company was a tiny startup the old nyc building door had an intercom buzzer and physical keys. To make it easier to get in I wired a raspberry pi w/relay into the intercom and built a web UI. The pi setup wasn’t solidly reliable for weeks at a time, but fortunately it was plugged into an outlet with a light switch so everyone knew to turn it off and back on again. But since it was by the door, no matter the labeling from time to time we’d come in to find it turned permanently off.
