Operating Instructions
Connecting to a Zigbee Hub
The Zemismart Zigbee LED Downlight requires a compatible Zigbee hub for smart functionality. This includes Zemismart Zigbee hubs (for HomeKit integration) or Tuya Zigbee hubs (for Echo and NEST integration). The hub performs multiple controls through Zigbee transmission to achieve non-series grouping control.

Voice Control
Once connected to a compatible Zigbee hub, you can control your downlight using voice commands:
- Siri: Via Zemismart Zigbee hub (works with HomeKit).
- Amazon Echo / Google NEST: Via Tuya Zigbee hub.
You can drive multiple LED Downlights at the same time, operate them by voice, or form groups for unified control. For example, you can say "Hey Siri, turn on the light in the bedroom for me?"
