Introduction
B
The YoLink Dimmer Switch is a smart dimmer style single-
pole light switch, for 120 to 250 VAC circuits and dimmable
light bulbs.
For full functionality, including functionality of the YoLink
app, your smart Dimmer Switch connects to the internet by
connecting wirelessly to one of our hubs (original YoLink
Hub or the SpeakerHub), not via WiFi or other wireless
methods. If you do not already have a YoLink hub, and
unless there is an existing YoLink wireless network in your
building (for example, an apartment complex or condo
building with a building-wide YoLink system), please
purchase and set-up your hub before proceeding with the
installation of your new Dimmer Switch.
Please note: the Dimmer Switch requires a neutral wire! It
will not function without a neutral wire. As explained in the
Installation section, you must identify the neutral wire in the
switch’s electrical box. If a neutral wire is not present, one
must be installed. Consult with or hire a qualified and
properly licensed electrician, as required.
Also note: the Dimmer Switch is not compatible with 3-
way switches or 3-way style wiring, but 3-way operation
functionality can be accomplished using two YoLink
Dimmer Switches, wired as standard switches, and paired
using Control-D2D pairing. This pairing process is
explained in the Control-D2D pairing section of this user
guide.
Refer to the Before You Begin section for additional
important information prior to installing your Dimmer
Switch.

The Dimmer Switch is generally compatible with the
following light bulb types, at their respective maximum
loads:

Do NOT overload or use your dimmer switch to control
receptacles, motor-driven appliances, or transformer-supplied
appliances.
Do review the environmental limitations of the Dimmer Switch
prior to installation. The Dimmer Switch is intended for indoor
locations, only!
Do familiarize yourself with this user guide prior to beginning
installation.
Do ensure that you are comfortable working with electricity and
handling the associated tools, or hire a qualified electrician to
install your Dimmer Switch!

Installation

Turn off the circuit that serves the switch at
the circuit breaker panel (or other means of
disconnecting the AC power to the circuit).
Do NOT work on “hot” electrical wiring!

Using a slotted screwdriver, remove the switch faceplate, then
using a slotted or Phillips screwdriver, remove the switch and
pull it away from the wall.
3
Before removing any wiring from the switch, identify the wires
on the switch and in the electrical box:
Ground wire: this wire is typically a bare copper wire, but it
may have a green jacket (insulation), or it may have another
color insulation with green tape identifying it as a ground.
Additional means of identification are the wire is terminated on
(connected to) a green screw on the switch, and/or the screw
or wire connection has a designation such as “GND” and/or
includes the universal earth ground icon:
Verify that power has been removed to the light switch, by
testing the switch, and by using a multimeter or other type of
voltage tester before removing any wires from the switch.
If replacing an existing switch, proceed to the next step. For
new installations, skip ahead to step 5.

Installation, Continued
G
11
Switch Leg Wire: this wire is typically black, but may be red or
another color. This is the wire that is energized when the switch
is on. After you have identified the ground and the hot wires on
the existing switch, the remaining wire should be the switch leg
wire. This wire can also be helpful in identifying the neutral wire.
While the existing switch you are replacing with the Dimmer
Switch may not have required a neutral wire, the light that it
controlled does require a neutral wire. Follow the switch leg
wire to its connections to another wire, or for it to join a “multi-
conductor” cable (a larger jacketed cable with two or more
different conductors within it). If the switch leg wire is in a
yellow jacketed cable, for example, that also has a white and a
bare copper wire with in it, this cable most-likely serves the
existing light, and you have also identified the neutral wire.
Neutral Wire: this wire is typically white. As explained above,
the light that is controlled by the existing switch will require a
neutral wire, making it easier to identify if it is in the box.
Otherwise, look for multiple white wires under one wire
connector in the electrical box. If you find a white wire with
black tape, this is likely a wire NOT used as a neutral; do not use
this wire! If you are still unable to identify a neutral wire, stop
and consult an electrician to have one installed, otherwise
contact us regarding questions about returning your Dimmer
Switch, if so desired.
Line or Hot Wire: this wire is typically black, but can be red or
another color, but if not it may be marked as the hot wire with
black or red tape. One of the wires on the existing light switch
should be the hot wire. Another way of identifying this wire is
that it may be connected to other wires in the box. If the box
contains multiple switches, for example, there will typically be a
hot wire that connects to each switch. Observe each of the
non-ground wires on the switch, looking for connections to
other black (or red) wires under a “wire-nut” or similar wire
connector.

Identify each wire with a marker, tape or other labeling
method, as desired, so they are not confused with each other
during the wire termination step.

Connect the Dimmer Switch’s “pigtail” wires (pre-installed
colored wires, connected to the switch) to your identified
wires. As shown in the example shown in Figure 1 below, and
using the included or existing “wire-nut” connectors:
Connect the switch’s green pigtail to the ground wire(s).
Connect the switch’s white pigtail to the neutral wire(s).
Connect the switch’s black pigtail to the hot wire(s).
Connect the switch’s red pigtail to the light switch leg wire.

Installation, Continued
G
13
Check each wiring connection by gently tugging on each
conductor, ensuring it does not pull out of the wire-nut or
appear loose. Re-do any that do not pass this test.
6
Gently push the wiring and the switch into the electrical box,
then secure the switch to the box using the included or
existing screws (if more suitable for the box).
7
Using the included screws, secure the faceplate mounting
plate to the switch, then mount the outer part of the faceplate
onto the mounting plate, snapping it into place. (If this switch
is in a multi-gang box, use the existing faceplate or furnish
one suitable for the switches in the electrical box.)
8
Turn on power to the circuit by returning the circuit breaker to
the on position (or reconnect power per your applicable circuit
disconnection method).
9
Test the switch by turning the light on and off.
