How to Install a Tuya Smart Switch

⚠️ Warning: Working with electricity can be dangerous. If unsure, consult a qualified electrician.

Practical Use Cases

1. Lighting Automation

Set schedules so lights turn on at sunset and off at bedtime.

Ensure lights turn off automatically when you leave the house.

3. Voice Control

Ask Alexa or Google to turn on/off specific lights without touching a switch.

4. Security Enhancement

Simulate presence by scheduling random light activations while away.

Control multiple switches or combine with Tuya plugs and bulbs in one scene.

Integrating with Voice Assistants

Once paired with Smart Life, you can connect to Alexa or Google Home. Example commands:

• “Alexa, turn off the bedroom light.”
• “Hey Google, dim the living room lights to 40%.”

Troubleshooting Tips

• Switch won’t connect? Ensure Wi-Fi is 2.4 GHz and reset the switch.
• Lights flicker? If using a no-neutral switch, try adding a capacitor.
