As smart homes become more common, some homeowners are going beyond basics like smart bulbs and assistant hubs like Google Home and Amazon Echo. This can take a number of forms, from the addition of smart electronics and security systems to sensors throughout the house that can recognize when people walk into rooms and adjust the lighting and other resources accordingly. One increasingly popular option is the installation of smart switches in lieu of simply relying on individual smart bulbs to control lighting.
So what are smart switches, anyway? How do they work? Can you install
them anywhere, or are there specific things that your home needs? If you’re
curious about smart switches and whether they would be a good addition to your
home, here are some of the basics that you should consider.
How Smart Switches Work
At their core, smart switches operate like most standard light switches
and can turn lights or other connected devices on and off. Given that the
switches are smart devices, though, they can do significantly more than that.
Smart switches allow you to control the lights remotely using either an app or
voice control through a digital assistant or a third-party hub. Depending on
the bulbs that you use with your smart switch, you may also be able to control
the brightness of the lights (similar to a dimmer switch) or function as a
three-way switch. It’s worth noting that unless the bulbs are designed for it,
smart switches can’t give you the ability to control the light’s color the way
that standard smart bulbs can.
Perhaps the greater benefit of smart switches is that they allow you to
tie your lighting into a larger smart ecosystem without having to pair each
individual light bulb to the network. This gives you greater control of your
home as a whole and allows you to incorporate lighting into smart home routines
without having to program a bunch of individual components. You can also pair
your smart switches with remote controls, giving you a portable switch that
lets you control your lighting even without accessing your overall smart home
controls.
Smart Switch Requirements
There are two major
things that you’re going to need to use smart switches in your home. Perhaps
the most important is grounded wiring, as all smart switches require grounding
to operate. If you’re upgrading light switches that weren’t grounded, you’ll
have to ensure that a ground wire is available, or your new switches simply
won’t work.
Once you’ve got your
switches grounded, you’re also going to need access to a 2.4Ghz Wi-Fi network.
While this is a standard Wi-Fi frequency, 5Ghz Wi-Fi is also increasingly
common, but is not compatible with most smart devices (including modern smart
switches). Almost all modern routers and wireless access points are capable of
broadcasting on both the 2.4Ghz and 5Ghz bands, so if you don’t have a 2.4Ghz
band currently at your home then it shouldn’t be too difficult to add one.
Installing Smart Switches
There are two aspects
to installing smart switches: installing the physical switch, and connecting it
to your Wi-Fi network. Installing the switch is similar to any other grounded
light switch installation, so it’s certainly doable as a DIY project if you
feel confident in your wiring abilities, but check with your code office to
make sure you’re allowed to do this kind of work. Once installed, the switch
can then be connected to your Wi-Fi network using the manufacturer’s smartphone
app on a phone or other mobile device that’s connected to the same network that
the switch will eventually use.
Since wiring a smart
switch involves dealing with electricity, if you aren’t confident in your
ability to install the switch, if your local code office requires an
electrician for that kind of work, or if you need a wiring upgrade, then you
should call in a professional.
