How do 4-Way Smart Dimmer Switches work?

All light switches have a similar purpose: allowing the electricity to flow through a completed circuit when the light is switched on, and cutting off the electricity when the light is turned off. 

However, 4-way switches behave a little differently. 

A 4-way switch has four terminals. They contain a traveler wire which provides two potential pathways to complete a circuit. 

This innovative design means you can have lots of 4-way switches in a circuit and control a single light from any of those switches! This is ideal for hallways, stairwells, or large rooms with multiple entrances. 

Additionally, a 4-way dimmer switch can also help you control a light's brightness. Typically, 4-way switches need to be wired to operate. However, some brands available on the market require only the master switch to be wired, while the add-on switches communicate via RF.

Features & Benefits of Smart Dimmer Switches

Comfort

4-way dimmer switches offer buyers the advantage of comfort and convenience. It almost feels like electrical wizardry when you don't have to drudge back to the lonesome switch in a big ole room to turn the lights off (or on). 

There's also the advantage of being able to dim lights or set a schedule or scene, thanks to the “smart” aspect of these switches. And, for the especially forgetful (like us), there's the handy feature of remote access, so you can turn off your lights no matter where you are.

Financial Advantages

Imagine a setup that allows you to manage a handful of lighting fixtures with a single kit or device. That means you can remotely control your lighting fixtures to suit your needs without even being at home!

Or what if you could control your lights to go off and on just after you leave or before you arrive? The point is, 4-way smart switches don't only offer comfort and ease, but you can also utilize them to save money on energy bills. What's not to like about that? 

Eco-friendly

We live in a world where climate change isn't just a possibility – it's reality. And if you're looking to contribute to a positive change for the environment, you can actually do so by installing smart switches. As crazy as that may sound, 3-way and 4-way setups help you cut down on unnecessary energy consumption, particularly for incandescent lights. 

Features like remote access control and even customizable scheduling afford you the chance to cut back on energy waste. 

Low-cost Crime Deterrent

Citizens of the United States face around 2.2 million burglaries per year, and the stats aren't all that better worldwide either. Being vigilant can go a long way in keeping you safe, but you can't be watchful when you aren't even home. 

That's where the “away” or “vacation” mode on 4-way smart dimmers can help. This feature is designed to turn your lights on and off randomly to keep intruders at bay. 

Voice Control Features

There are no two ways about it – voice control via virtual assistants like Alexa, or Google Assistant are a great time saver!

It doesn't always have to be the lazy option either, when you're too tired to move. Voice control is essential in situations where folks are dealing with limited mobility due to medical concerns, recovery from surgery, etc. 

Conclusion

So there you have it. With these 4-way smart dimmer switches, you can now upgrade the lighting in hallways and large rooms. With it you get all the advantages like remote access control, personalized schedules, lighting scenes, and they can even help you reduce your energy bills!
