How to Add a Hue Dimmer to your Hue System
To add your Hue dimmer to your hue system, open your Philips hue application and tap on the gear icon on the top right to open the settings menu.
Pull the clear plastic tab that is hanging out of the battery door to enable the battery.
You will need a paper clip to press in the small pinhole button which will put the dimmer in setup mode. Press in the pinhole button for 1 second, then orange light on the front will blink every two seconds if it is ready to be paired. If it is blinking press the LED Blinking button to start searching for the dimmer.
