4. Discovering Devices: The app will search for nearby devices. Select "Mini Dimmer switch" when it appears.
5. Connect to WiFi: Choose your 2.4GHz WiFi network and enter the correct password. (Note: The module only supports 2.4GHz WiFi networks).
6. Device Added: Once connected, the app will confirm "Device(s) added successfully". You can then rename your device for easier identification.

5.3. Bluetooth Function Operation (for initial pairing)

If you are using a Bluetooth-assisted pairing product, power on the device first. Then, enable Bluetooth on your mobile phone and open the App. Bluetooth devices ready for pairing will be displayed, allowing for a quicker setup.

5.4. App Interface Overview

After successful pairing, the app interface will allow you to control the brightness (from 1% to 100%), adjust the dimming range, and select the light type (LED, Incandescent, Halogen) for optimal performance.

5.5. Note on Zigbee Devices

While the provided manual mentions Zigbee device setup, this specific product is a WiFi Smart Dimmer Switch Module. The Zigbee instructions are for general Tuya/Smart Life ecosystem devices. This WiFi module does not require a Zigbee gateway.

6. Operation

6.1. Stepless Dimming

You can adjust the light brightness seamlessly using:

• Smart Life/TuyaSmart App: Use the brightness slider in the app.
• Voice Commands: (See section 6.2)
• Original Wall Switch: The module is compatible with your existing wall switch, allowing you to turn lights on/off and often dim (if your switch supports it or if it's a momentary switch). The module remembers the last brightness setting when powered off.

6.2. Voice Control

The dimmer switch is compatible with Amazon Alexa, Google Home Assistant, and Yandex Alice. Link your TuyaSmart/Smart Life account to your voice assistant app to control your lights with simple voice commands:

• "Alexa, set [Light Name] to 50%."
• "Hey Google, dim [Light Name]."
• "Alexa, turn off [Light Name]."

6.3. Timing Function (Schedules)

Create schedules within the app to automatically turn your lights on or off at specific times, with preset brightness levels. This is perfect for:

• Waking up with gradually brightening lights.
• Ensuring lights are off when you leave home.
• Creating ambiance for different activities (e.g., movie night, reading).
• Simulating occupancy when you are away.

6.4. Group Control

If you have multiple dimmer modules, you can create groups within the app to control several lights simultaneously with a single tap or voice command. For example, you can create a "Living Room Lights" group to control all lights in that area.

6.5. Relay Status Setting

The module features a relay status setting, allowing you to configure its behavior after a power outage. You can set the switch to restore its last known state (on/off/brightness) when power is restored, ensuring your lighting preferences are maintained.

7. User Tips

• Dimmable Bulbs are Key: Always ensure you are using dimmable LED or incandescent bulbs. Non-dimmable bulbs will not work correctly and may flicker or be damaged.
• 2.4GHz WiFi Only: The module connects only to 2.4GHz WiFi networks. If you have a dual-band router, ensure your phone is connected to the 2.4GHz band during setup.
• No Energy Monitoring: This dimmer module does not include an active power meter sensor for energy monitoring.
• Power Outage Behavior: If your WiFi goes off, you can still control the connected light with your traditional wall switch. Once WiFi is restored, the device will automatically reconnect to your network.

8. Troubleshooting (FAQ)

Q1: What should I do if I can't configure the smart module or it won't connect to WiFi?

• Check Power: Ensure the device is powered on.
• WiFi Band: Make sure your mobile phone and the switch module are both connected to the same 2.4GHz WiFi network.
• Internet Conditions: Verify that your internet connection is stable and strong.
• Password: Double-check that the WiFi password entered in the app is correct.
• Wiring: Confirm that the wiring is correct according to the diagram in Section 4.
• Reset: If issues persist, try resetting the module (refer to the app for specific reset instructions, usually involves cycling power or holding a button).

Q2: What happens if the WiFi goes off?

You can still control the device connected to the smart module with your traditional wall switch. Once WiFi is active again, the device will automatically reconnect to your WiFi network.

Q3: What should I do if I change the WiFi network or change the password?

You will need to re-connect your WiFi smart module to the new WiFi network. This typically involves putting the module back into pairing mode and following the app setup steps again, as outlined in Section 5.

9. Maintenance

• Cleaning: Clean the device with a soft, dry cloth. Do not use harsh chemicals or abrasive cleaners.
• Firmware Updates: Periodically check the TuyaSmart/Smart Life app for available firmware updates to ensure optimal performance and security.
