Getting Started

Hardware Requirements

1. ESP32 Board: ESP32, ESP32-S2, S3, C3, etc.
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, for example, the Waveshare Pico-DALI2.
   • RX Pin: Configurable (build-time).
   • TX Pin: Configurable (build-time).

Flashing & First Boot

1. Get and unpack firmware last release to your ESP32;
2. Run the flash.sh script to flash the firmware to your ESP;
3. On the first boot, the device will be in Provisioning Mode.

Provisioning Mode

If the device is not configured, it starts a WiFi Access Point:

• SSID: DALI-MQTT-Bridge
• Password: bridge123 (or as configured in CONFIG_DALI2MQTT_WIFI_AP_PASS)
• WebUI: Device DHCP IP or http://dalimqtt.local mdns domain

Login with default credentials:

• User: admin
• 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.
