1. Desconectar a enerxía: Before beginning, ensure the main power supply to your electrical panel is completely turned off. Verify with a voltagprobador.
2. Montaxe: Clip the Nous D1T onto the DIN rail. Ensure it is securely fastened.
3. Cableado: Connect the live (L) and neutral (N) wires from your power source to the "N Power" and "L Power" terminals on the top of the device. Connect the neutral (N) and live (L) wires of your load (appliance/circuit) to the "N Load" and "L Load" terminals on the bottom. Refer to the wiring diagram below.

Figure 2: Nous D1T wiring diagram.

This image illustrates the Nous D1T smart switch with its electrical connection points clearly labeled. The top terminals are for incoming power (N Power, L Power), and the bottom terminals are for connecting to the load (N Load, L Load). The diagram also shows the maximum wire diameter of 2.5mm and the DIN rail mounting mechanism.

2. Initial Configuration (Tasmota)

The Nous D1T comes pre-flashed with Tasmota firmware, allowing for flexible configuration.

1. Encendido: Restore power to your electrical panel. The device will create a Wi-Fi access point (AP) named "tasmota-XXXXXX".
2. Connect to AP: Using a computer or smartphone, connect to the "tasmota-XXXXXX" Wi-Fi network.
3. Acceso Web Interface: Abrir a web navegador e navegue ata 192.168.4.1. This will open the Tasmota web interface.
4. Configurar o Wi-Fi: In the Tasmota interface, go to Configuration > Configure Wi-Fi. Select your home Wi-Fi network (2.4 GHz only) and enter the password. Save the settings. The device will restart and connect to your network.
5. Find Device IP: Once connected to your home network, the device will obtain a new IP address. You can find this IP address through your router's connected devices list or by using a network scanner tool.
6. Access Device: Abrir a web browser and navigate to the device's new IP address to access its Tasmota interface.

This image displays the comprehensive configuration menu within the Tasmota web interface. Options include configuring Wi-Fi, MQTT, Domoticz, Timer, KNX, Matter, Logging, and more. It also provides options to reset, backup, or restore the configuration, offering advanced control over the device's functionality.

Operating the Nous D1T

1. Control básico de acendido/apagado

• Botón manual: Press the physical button on the device to toggle the connected load On or Off.
• Web Interface: Acceder á Tasmota web interface (Figure 3) and use the "Toggle 1" button to control the relay.

2. Monitorización enerxética

The Nous D1T provides real-time and historical energy consumption data.

• Datos en tempo real: View current Voltage, Current, Frequency, and Power directly on the Tasmota main status page (Figure 3).
• Datos históricos: The interface also displays accumulated energy consumption for "Energy Today," "Energy Yesterday," and "Energy Total." This data can be used to analyze energy usage patterns and optimize consumption.

Figura 5: Tasmota Web Interface - Energy Monitoring.

This image highlights the energy monitoring capabilities of the Nous D1T via its Tasmota web interface. It shows various energy metrics including Voltage, Current, Frequency, Active Power, Apparent Power, Reactive Power, Power Factor, and accumulated energy usage for the current day, previous day, and total. This allows users to track and manage their power consumption effectively.

3. Smart Home Integration (MQTT, Matter, Home Assistant, Voice Control)

The Nous D1T is highly compatible with various smart home ecosystems:

• MQTT: Configure MQTT parameters (Host, Port, Client, User, Password, Topic) in the Tasmota interface (Configuration > Configure MQTT) to integrate with MQTT brokers for advanced automation.
• Materia: Enable Matter support via the Tasmota interface (Configuration > Configure Matter) for seamless integration with Google Home, Amazon Alexa, and Apple HomeKit.
• Asistente de fogar: The Tasmota firmware allows for easy discovery and integration with Home Assistant, providing a centralized control platform for your smart devices.

Resolución de problemas

Problemas comúns e solucións:

• O dispositivo non responde:
  • Comprobe a fonte de alimentación do dispositivo.
  • Verify Wi-Fi connectivity. Ensure the device is within range of your 2.4 GHz Wi-Fi network.
  • Restart the device by cycling its power.
• Non se pode acceder Web Interface:
  • Ensure your device (computer/smartphone) is on the same network as the Nous D1T.
  • Verify the IP address of the Nous D1T. It might have changed if your router assigns dynamic IPs.
  • Try accessing the device by its hostname (e.g., `tasmota-XXXXXX.local` if mDNS is enabled).
• Incorrect Energy Readings:
  • The device may require calibration for accurate energy monitoring. Refer to Tasmota documentation for calibration procedures (e.g., using `PowerSet`, `VoltageSet`, `CurrentSet` commands in the console). This typically involves connecting a known load and adjusting parameters.
• Matter/MQTT Integration Issues:
  • Double-check all configuration parameters (host, port, credentials, topics).
  • Ensure your MQTT broker or Matter controller is running and accessible.
  • Check Tasmota console logs for error messages related to MQTT or Matter connection.

Restablecemento de fábrica:

If issues persist, a factory reset can restore the device to its default Tasmota configuration. This will erase all Wi-Fi and custom settings.

• Método 1 (Botón): Press and hold the physical button for approximately 40 seconds until the indicator light flashes rapidly, then release.
• Método 2 (Web Interface): In the Tasmota web interface, navegue ata Configuration > Reset Configuration and select the appropriate reset option (e.g., "Reset 1" for Wi-Fi and module settings).
