Step-by-Step Setup

1. Ensure Zigbee hub is set up: Your Tuya Zigbee hub must be online and connected to the app first.
2. Turn off power: Switch off the circuit breaker for the light circuit.
3. Remove old switch: Unscrew and disconnect the existing dimmer or switch.

   • L1 → Load (to dimmable lights)
   • N → Neutral
   • Ground → Ground wire
5. Mount the switch: Install in electrical box and attach faceplate.
6. Restore power: Turn the circuit breaker on. The dimmer will power up.
7. Put hub in pairing mode: In the Tuya app, go to your hub and tap "Add subdevice."
