What to Consider When Looking for a Smart Light Switch

The best smart light switches function just like a traditional light switch when you touch them on the wall. However, they also may be operated by a mobile device from anywhere in the world or respond to verbal commands that you give to a digital assistant.

Smart light switches may have a motion sensor and be dimmable. You can even program them to turn off and on according to your schedule. Of course, not every smart switch has all of these capabilities, You’ll want to review the features of every model before making a purchase decision.

Is a Hub or Bridge Required?

Some smart light switches operate just with your WiFi signal. You can integrate them with a digital assistant or not. However, some of them require that you also purchase a central hub or bridge that operates the system. Some of these hubs also may wirelessly connect to other devices for increased home automation options.

A hub represents an additional expense, but it’s usually not too great, especially if you get a starter kit with a switch and a hub. Some of these packages also include a remote. If you’re into the idea of a system that includes a hub, then be aware of any limitations this may impose on you. For instance, some hubs are only able to reach across a finite distance.

It’s a lot like choosing the best outdoor solar lights when you’re choosing the best smart light switch. Some options may work for you while others will not.

Using a Digital Assistant with a Smart Switch

Smart switches may be integrated with numerous digital assistants like Amazon Alexa, Google Assistant and Apple HomeKit among others. If you already have a digital assistant, then it makes sense to ensure that the switch you choose is compatible so that you get the most functionality out of it.

Q: How does a smart light switch work?

A: Smart light switches are designed to replace traditional light switches in the home and workplace. They can be installed directly into the existing back boxes, and they even function like a traditional light switch. However, they have some obvious upgrades.

Smart light switches also are WiFi devices that can be remote controlled with an app on your phone or a digital assistant. This lets you control the lighting in your home regardless of your physical location. When at home, just ask your digital assistant to turn on or off any switch-controlled devices that are connected to your smart light switch.

While some smart light switches operate via a hub or bridge, others do not require this extra equipment. A WiFi signal is all that they really need.

Q: Should I get smart bulbs or switches?

A: If you’re looking for a quick and easy smart home upgrade, then smart bulbs may be the way to go. It’s as easy as switching out the existing bulb for a smart one. However, they don’t always work with dimmers, and the light has to actually be switched on to take advantage of the possibilities.

Smart light switches do not require smart bulbs. Ultimately, a smart switch offers greater versatility and options. It probably makes sense to get some switches first, then see if you want to upgrade a few bulbs.

Q: Can a smart light switch go bad?

A: Like any other electronic device, it is possible that a smart light switch may wear out or become less functional over time. However, this is unlikely, and as long as the WiFi connection remains strong and secure, there is little to worry about.

Q: Can smart switches dim regular light bulbs?

A: Yes, many smart light switches that include a dimmer can dim traditional light bulbs.
