By using a simple key fob, I can arm or disarm my alarm system (managed via <strong>Alarmo</strong>) as I enter or leave. The system is based on an ESP8266 microcontroller, integrated seamlessly into Home Assistant using ESPHome.</p> <h3 id="hardware-components">Hardware Components</h3> <ul> <li><strong>Microcontroller:</strong> ESP8266 (D1 Mini)</li> <li><strong>NFC Module:</strong> PN532 NFC Board (connected via I2C)</li> <li><strong>Indicator:</strong> RGB LED (for real-time status feedback)</li> <li><strong>Power:</strong> Standard 5V USB Power Supply</li> </ul> <hr> <h2 id="1-esphome-integration">1.
