FAQs

What is the difference between a wall switch and a wireless switch?

The wall switch is a common electrical device that enables people to have control over the electrical current of a circuit. Wall switches make it possible to turn the lights or other appliances on and off, by pressing the physical wall switches or remote control.

A wireless switch uses wireless compatibility to power light fixtures throughout your home. There are more wireless smart switches that can be controlled by APP, smartphone, smart home hub, smart button and more. This eliminates many safety concerns that often come with wall switches, and also makes for a more convenient experience by controlling the lights from the palm of your hand. To install smart wireless switches in a house that doesn’t have a neutral wire, we should either implement a rewiring, or a no-neutral wire-designed smart wireless switch is required.

What are the benefits of a smart switch?

Creating a more digitally inclined living space comes with many benefits. Some of the advantages include:

1.Security. Controlling the lights from anywhere at any time, even when you’re away from home, can provide a sense of safety and security.

2.Saved money. With an eco- and energy-efficient mindset, you can save money with the smart switch by programming when the lights go on and off.

3.Convenience. Don’t leave your bed to get up and turn off the lights. Enjoy the convenience of controlling your lighting with your smart device instead.
