- On the Sylvania Smart Dimming Switch, press and hold both buttons simultaneously for approximately 3 seconds until the indicator light flashes.
- The switch will attempt to pair with the hub. Once successfully paired, the indicator light will typically stop flashing or change color according to your hub's feedback.
- Use your smartphone application for the ZigBee hub to confirm the switch has been added and to assign it to specific lights or groups.
4.2. 物理的なインストール(オプション)
The switch can be installed over an existing light switch to prevent accidental power cuts to your smart lights. Choose the appropriate backing plate (rocker, toggle, or solid) for your existing switch type.
