Big LazyBone Wi-Fi Dimmer – (Andorid/iOS)

The Big LazyBone Bluetooth dimmer is a smartphone dimmer that has integrated Bluetooth 4.0 and a microcontroller.

It supports both Android and iOS. So, you can use your iPhone or Android phone to control this Big LazyBone dimmer.

Connect your lamp to it, you can dim the light using your Android/iOS smartphone or a computer.

It is compatible with AC 100-240V 50/60Hz which makes it usable worldwide.

After you connect this Lazybone device to your smartphone, you will see a virtual knob on the app user interface. Rotating the virtual knob will change the voltage at the dimmer ports. Dimming of light will also appear as the voltage level changes.

Compared to the previous LazyBone dimmer, the Big LazyBone offers a number of improvements. It can be set as a leading or trailing edge dimmer. It can work with an incandescent bulb, LED bulb (must be a dimmable one) or AC motor. It also has a real knob that can dim the light/motor speed manually.


Note: For LED Bulb dimming, please set to Trailing edge mode.

Note: Because of the AC waveform change, the AC motor will have some noise output when you use this dimmer.
