App Operating Instructions

  1. Register an accountTuya Smart App is compatible with iOS and Android systems. Scan the QR code below with you mobile phone and follow the prompts to complete the app installation. After installation being completed, you can log in or register an account.APP supportApp download 
  2. Paring instructionsA new user clicks “Me” → → a Home “, give a name to your home and confirm your home location, then add the rooms you need. Click “Add Device” – “Auto Scan” and enable permissions for automatically scanning Bluetooth/Wi-Fi/Zigbee/wired devices. Follow the prompts to add the device (Ensure that the device is ready for network connection)
  3. Lighting control settingsAfter paring up your device, click the device you add and adjust to your desired lighting status by brightness changing and color temperature adjustment.In “Settings”, there are also lighting alarm clock (Tuya Bluetooth Gateway needs to be added) and countdown functions.

  4. Remote control and automation4.1 Remote control: Add Tuya Bluetooth MESH(SIG) Gateway by search bluetooth devices, and follow the prompts to configure the gateway to the network. After configuring the network, access the gateway interface and click “Add to the list” or “Search for new devices” to add the device to the gateway, and then the device can be controlled remotely.4.2 Automation settings: After adding Tuya Bluetooth MESH(SIG) Gateway , you’ll be able to control the lighting remotely by clicking ”Automation” in the “Smart” menu. In “Automation”, set up conditions from weather, location and timing to other device status so as to trigger the lighting effects you preset and realize the lighting automation.

Reset The Device (Reset to factory defaults)

When the driver is power-on, turn off and after 10s turn it on. After 2s, turn it off again. Repeat the same operation 5 times and then turn on the driver again. When the lamp is flashing (2 flashes/s), reset the device successfully.
