2. DALI Physical Interface: The ESP32 operates at 3.3V. The DALI bus operates at ~16V. You need a hardware interface (circuit) containing optocouplers/transistors to convert the signal.
   • RX Pin: Configurable (build-time).

Flashing & First Boot

1. Flash the firmware.bin and spiffs.bin (WebUI) to your ESP32.

• Pass: dalimqttbrg12321

Go to Settings and configure:

1. WiFi SSID & Password: To connect to your home network.
2. MQTT Broker: URI (e.g., mqtt://192.168.1.10:1883), User, Password.
3. Client ID: Unique name for this bridge.
4. Save & Reboot.

Normal Operation

After reboot, the device connects to your WiFi.

• WebUI: Accessible at http://<device-ip>/ or via mDNS http://<http_domain>.local.
• Status LED: (If configured) indicates MQTT connection status.
