Turning a Dumb AC Unit Smart Without Losing My Security Deposit

Turning a Dumb AC Unit Smart (Without Losing My Security Deposit)

After moving to a New York City apartment with only analog AC controls, I built a DIY automation system using an ESP32 and a stepper motor. Instead of risky electrical modifications, I rigged a low-cost robot to turn the temperature dial, integrating it with Home Assistant via MQTT. This janky but effective solution lets me control the unit from my couch while keeping my security deposit intact.
