Wiring diagram for the MOES 2-gang smart switch. The diagram shows connections for neutral (blue), live (black), and two lamp wires (red) to two light bulbs. The switch itself has terminals for N (Neutral), L (Live), L1 (Lamp 1), and L2 (Lamp 2).
Installation Steps
- Turn Off Power: Locate your circuit breaker and turn off the power to the switch you are replacing. Verify power is off using an electric pen.
- Remove Old Switch: Carefully remove the faceplate and unscrew the old switch from the wall box. Disconnect the wires.
- Connect Wires: Connect the neutral wire (blue), live wire (black), and lamp wires (red) to the corresponding terminals on the MOES Smart Switch. Refer to the wiring diagram for precise connections.
- Mount New Switch: Secure the new smart switch into the wall box using screws. Attach the glass panel.
- Restore Power: Turn the circuit breaker back on.
App Pairing (Smart Life/Tuya App)
The MOES Smart Switch uses the Smart Life or Tuya App for smart control. Ensure your phone is connected to a 2.4GHz Wi-Fi network and Bluetooth is enabled.
- Download and open the Smart Life or Tuya App.
- Click the "+" icon in the upper right corner to add a device.
- The app should automatically detect the new switch. If not, select "Electrical" then "Switch (Wi-Fi)" or similar.
- Enter your 2.4GHz Wi-Fi network password and confirm.
- The switch will connect to the app. Once added, you can rename the switch and access its settings.

The Smart Life app simplifies the pairing process with automatic identification and quick connection.
How to Reset/Re-pair Wi-Fi Code
To reset the Wi-Fi code or re-pair the switch, press the switch button for 6 times. On the 6th time, hold the button until you hear "Di-Di" (2 times). The blue indicator on the switch will then flash fast after 3 seconds, indicating it's ready for re-pairing.
Operating the Smart Switch
Touch Control
The glass panel allows for effortless touch control. Simply tap the circular icons on the switch to turn the connected lights on or off.
App Control
Once paired with the Smart Life/Tuya App, you can control your lights from anywhere using your smartphone. The app provides ON/OFF functionality, scheduling, timers, and other advanced settings.
RF433 Remote Control
The built-in RF433 frequency allows for control via an RF remote control switch (not included) with encoding 1527. This provides an additional, independent control method.

Voice Control (Alexa and Google Home)
The smart switch is compatible with Alexa and Google Home for hands-free voice control. After pairing the switch with the Smart Life/Tuya App, link your Smart Life/Tuya account to your Alexa or Google Home app. You can then use voice commands like "Alexa, turn on the living room light" or "Hey Google, turn off the bedroom light."

The smart switch supports various control methods including RF433 remote, Smart Life/Tuya app, voice control via Alexa, and direct touch control.
Multi-Control Association (3-Way Functionality)
Achieve 3-way circuit functionality (two switches controlling one light) by associating this smart switch with other Wi-Fi smart switches via the app. This eliminates the need for complex wiring between the two switches, requiring only L and N wires for the new added switch.

Multi-control association allows two smart switches to control a single light without additional wiring between them, managed through the Smart Life app.
Customize Schedule and Timer
Take full control of connected appliances with timers, schedules, and countdown options (e.g., 1/5/30 minutes, 1 hour) directly from the Smart Life/Tuya App. This allows for automated lighting control based on your daily routine.
Relay Status and Backlight Settings
The upgraded Smart Life/Tuya App allows you to set the ON/OFF relay status to remember the last state when power is off. You can also adjust the backlight switch setting to turn it off, preventing any interference with sleep.

The backlight of the smart switch can be turned off via the app to avoid disturbing sleep.
Maintenance
To maintain the appearance and functionality of your smart switch, wipe the glass panel with a soft, damp cloth. Avoid using abrasive cleaners or solvents that could damage the surface. Ensure the switch remains dry and free from moisture.
Troubleshooting
- Switch Not Responding: Check if the circuit breaker is on. Ensure the neutral wire is correctly connected.
- App Connection Issues: Verify your phone is connected to a 2.4GHz Wi-Fi network. Ensure the switch is within range of your Wi-Fi router. Try resetting the Wi-Fi code on the switch and re-pairing with the app.
- Voice Control Not Working: Confirm the Smart Life/Tuya account is correctly linked to your Alexa or Google Home app. Check your internet connection.
- Lights Flicker: Ensure the connected bulbs are compatible with smart switches and meet the power requirements.
