This TeapotOS project was a quick proof of concept where we turned a regular teapot into a smart device controlled through both a terminal and Alexa. Using an ESP32, a temperature sensor, and a relay, the system could monitor water temperature and adjust the heating based on voice commands. Most of the challenges came from the hardware side, especially working with the I2C sensor and safely switching high-voltage power with low-voltage control signals. In the end, we built a fully functional smart teapot in one night, giving us both a fun project and some hands-on experience with IoT device design and rapid prototyping.
