Bluetooth Smart Lightbulbs offers a simple and convenient way to control your smart LED lights. The app allows you to control the lights from anywhere, anytime, through a front page widget or through a simple menu.
The front page widget can be found in the settings of your device. To use the widget, simply open the app and find the widget. There, you can set the color, the number of lights, and the brightness. If you’re not using the front page widget, you can still access the lightbulbs through a simple menu.
To change the color of the lights, select a color from the color palette and click the color to change it.
The app also has a schedule function. It allows you to control the lights according to a schedule that you have created. To create a schedule, enter the control page of a single light bulb, and then enter the management entrance of schedules.
