- Make sure the device is within range of your Wi-Fi router (for WiFi version) or ZigBee hub (for ZigBee version).
- Verify that your ZigBee hub is properly connected and online (for ZigBee version).
- Restart your router/hub and try pairing again.
8.2. Lights Not Dimming or Responding
- Confirm that the light fixture uses a DC0-10V dimming driver. This module is not compatible with other dimming protocols or non-dimmable lights.
- Comprobe se todas as conexións do cableado están soltas ou colocadas incorrectamente.
- Asegúrate de que o módulo recibe enerxía.
- Verify the module is connected to the app and shows an online status.
- If using voice control, ensure the voice assistant is correctly linked to your Tuya Smart/Smart Life account.
8.3. Intermittent Connectivity
- Improve Wi-Fi signal strength by moving the router closer or using a Wi-Fi extender.
- For ZigBee, ensure the hub is centrally located and there are enough ZigBee devices to create a strong mesh network.
- Comprobe se hai interferencias doutros dispositivos de 2.4 GHz.
9. Consellos de usuario
- Label Your Wires: Before disconnecting any wires during installation, use electrical tape and a marker to label them (e.g., Line, Neutral, Load, Switch) to avoid confusion.
- Test Before Closing: After wiring but before fully securing the module and switch plate, temporarily restore power to test the basic on/off and dimming functionality.
- Explore Automation: Beyond simple schedules, use the app's automation features to create scenes (e.g., "Movie Night" scene dims lights to 30%) or link with other smart devices (e.g., lights turn on when a motion sensor is triggered).
