SmartPhone Controlled Light Dimmer – LazyBone Dimmer (Bluetooth)

Are you in Australia looking for masks?

This LazyBone dimmer is a smart dimmer that has integrated a microcontroller and a powerful Bluetooth with a control distance up to 30m (outdoor).

When you connect your lamp with it, you can dim the light using your Android/iOS smartphone or a computer.

It comes with 2 ports for AC input and 2 dimmer ports for AC output. It is compatible with AC 100-240V 50/60Hz which makes it usuable 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 voltage at the dimmer ports. Dimming of light will also appear as the voltage level changes.

Note: This dimmer can only work with incandescent bulb. It does not work with LED bulb or fluorescent lamp. However, it can be used as an ON/OFF switch for every kinds of lamp.

Software Installation:

It has 2 basic versions: Bluetooth and WIFI. And this is the Bluetooth LazyBone dimmer. If you want a WiFi LazyBone click here.

We provide free APP for you to control it. You can control multi Lazybones by this one APP.

How to use the software:

1. Open the app, if Bluetooth of your phone is inactive, it will prompt a message to activate it.

2. Click the Menu and then ‘Connect device’. Phone will detect the Bluetooth device automatically and input the PIN number: ‘1234’ (it will auto connect next time). When you connect your lamp for the first time, you can assign a name for it, for example: Room, Home, etc.
