🎉 Video Summary
I kept forgetting to brush my teeth, so I built a smart toothbrush holder using an ESP32-C6, reed switches and ESPHome. After limit switches and IR sensors failed on weight and battery life, magnets saved the day. It now logs brushing sessions to Home Assistant. Sponsored by JLCPCB.
