Installing your Tuya Smart Switch is a straightforward DIY project. Follow this guide to get your WiFi or Zigbee 3.0 switch up and running safely.
⚠️ Safety First
- Turn off the main power at the circuit breaker before installation.
- If you are unsure about electrical wiring, please consult a qualified electrician.
- Ensure the load does not exceed the maximum rated power (usually 500W-1000W depending on the model).
Step 1: Identify Your Wiring Type
Before you begin, check the wires in your wall box:
- With Neutral Wire: You will see a Live wire (Brown/Red) and a Neutral wire (Blue).
- No Neutral Wire (Single Fire): You will only see the Live wire and the Lamp wires. Use our “No Neutral” model for this setup.
Step 2: Wiring Diagrams
Option A: Wiring With Neutral (Standard Setup)
- Connect the Live wire to the L terminal.
- Connect the Neutral wire to the N terminal.
- Connect the Lamp wire(s) to the L1, L2, or L3 terminals.
Option B: Wiring Without Neutral (Single Fire Setup)
- Connect the Live wire to the L terminal.
- Connect the Lamp wire to the L1 terminal.
- Crucial Step: Install the included Capacitor across the L1 and Neutral terminals of your light bulb (not behind the switch) to prevent flickering.
Step 3: Mounting the Switch
- Neatly tuck the wires back into the wall box.
- Secure the switch base using the provided screws.
- Snap the tempered glass panel onto the base.
- Restore the power at the circuit breaker.
Step 4: App Configuration (Tuya/Smart Life)
For WiFi Version:

- Follow the on-screen prompts to complete the setup.
For Zigbee 3.0 Version:
- Ensure your Tuya Zigbee Gateway is online.
- Set the switch to pairing mode (long press until it flashes).
