5. Setup
5.1 Important Note on Zigbee Gateway
NOTE:
The Zigbee controller must work with a Zigbee 3.0 Gateway (Zigbee Hub include Philips Hue or Samsung SmartThings Bridge or Tuya Bluetooth/WiFi Dual-Mode Gateway). If there's no Zigbee Hub at your home, then you can't connect to your lights for smart control.

Description: This image and accompanying text explain the necessity of a Zigbee 3.0 Gateway (Hub) for the smart LED strip to function. It illustrates the connection flow: Zigbee Gateway connects to a WiFi Router, which then communicates with the Smart Zigbee Light Strip. Both APP Control and Voice Control interact with the Zigbee Gateway.
5.2 Physical Installation
- Prepare the Surface: Ensure the surface where you intend to install the LED strip is clean, dry, and smooth.
- Peel and Stick: Carefully peel off the protective backing from the 'Light Strip Back Sticker' on the LED strip.
- Adhere the Strip: Press the LED strip firmly onto the desired surface.
- Connect Power: Plug the USB connector of the controller into a standard USB 5V power source (e.g., TV USB port, USB wall adapter, power bank).
- Cropping (Optional): If you need to shorten the strip, cut only along the designated cutting marks (usually indicated by copper pads or scissor icons). Do not cut elsewhere, as this will damage the strip.

Description: This image illustrates three key features of the LED strip: it has a 'Light Strip Back Sticker' for easy installation, it 'Can Be Cropped' at designated points for custom lengths, and it offers 'Good Flexibility' for various mounting surfaces.
5.3 Tuya App Setup
- Download Tuya App: Download the "Tuya Smart" or "Smart Life" app from your smartphone's app store (iOS App Store or Google Play Store).
- Register/Login: Open the app and register for a new account or log in if you already have one.
- Set up Zigbee Gateway: Ensure your Zigbee 3.0 Gateway is already set up and connected to your home Wi-Fi network according to its own instructions.
- Add Device: In the Tuya app, tap the "+" icon (usually in the top right corner) to add a new device.
- Select Device Type: Select "Lighting" or "Light Source" and then choose the appropriate Zigbee light type (e.g., "Zigbee Strip Light" or "Zigbee Light").
- Pairing Mode: Follow the app's instructions to put the LED strip into pairing mode. This usually involves turning the light strip on and off a few times using the inline controller or power source until it starts blinking.
- Connect: The app will search for and discover your LED strip via the Zigbee Gateway. Once found, confirm the connection and rename the device if desired (e.g., "TV Backlight", "Kitchen Strip").
5.4 Voice Control Integration (Alexa/Google Home)
