How to Install Wi-Fi Tuya App Smart Light Bulbs: A Complete Guide

Smart light bulbs are a game-changer for modern homes, offering remote control, scheduling, and even color-changing features. If you’ve purchased Tuya-compatible smart bulbs and want to set them up with the Tuya Smart or Smart Life app, this step-by-step guide will walk you through the installation process.


What You’ll Need Before Setup

Before installing your Tuya smart bulb, ensure you have:
✅ A Tuya-compatible Wi-Fi smart bulb (e.g., from brands like Merkury, Teckin, or other OEM manufacturers).
✅ A 2.4GHz Wi-Fi network (most smart bulbs don’t support 5GHz).
✅ A smartphone (iOS or Android) with the Tuya Smart or Smart Life app installed.
✅ A standard light fixture or lamp to screw the bulb into.


Step 1: Download the Tuya Smart App

Both apps function similarly—choose one and install it.


Step 2: Prepare Your Smart Bulb

  1. Screw the bulb into a lamp or fixture (ensure the power is ON).

  2. Turn the light switch on—the bulb should glow (usually in default white/yellow).

  3. If the bulb flashes/blinks, it’s in pairing mode. If not, turn it off and on 3-5 times until it flashes.


Step 3: Connect the Bulb to Wi-Fi

  1. Open the Tuya/Smart Life app  Sign up or log in.

  2. Tap "Add Device" (usually a + icon).

  3. Select "Lighting"  "Wi-Fi Light".

  4. Choose your 2.4GHz Wi-Fi network and enter the password.

  5. The app will search for the bulb—wait for it to appear.

  6. Once detected, name your bulb (e.g., "Bedroom Light") and assign it to a room.

💡 Troubleshooting Tip:

  • If the bulb isn’t found, reset it by turning it off/on 5 times.

  • Ensure your phone is not on 5GHz Wi-Fi during setup.


Step 4: Control Your Smart Bulb

Once connected, you can:

  • Turn the bulb on/off remotely

  • Adjust brightness & color (if RGB)

  • Set schedules (e.g., sunrise simulation)

  • Enable voice control (Alexa, Google Assistant, Siri)

Voice Control Setup

  • For Alexa: Open Alexa app → Skills & Games → Enable "Tuya Smart" → Discover devices.

  • For Google Assistant: Open Google Home → Add device → Link Tuya/Smart Life.
