Halogen/Incandescent:
Maximum 400W
Multi-Switch Junction Box (with more than 2 dimmer switches installed):
LED/CFL: Maximum 150W

Note: The number of lights the smart dimmer switch can control depends on the
type of bulb and whether multiple dimmer switches are installed in a multi-switch
junction box.

dimmer switch can support 15 bulbs. If you use LED 15W bulbs, the dimmer switch
can support 10 bulbs.

To reduce the risk of injury and/or damage to this
dimmer switch, please read and follow all instructions
and safety guidelines in this manual.
Installation
WARNING: RISK OF ELECTRIC SHOCK OR FIRE
• Before installing and wiring, TURN OFF POWER by locking
the appropriate circuit breaker in the OFF position or
removing the appropriate fuse. Use a non-contact voltage
tester to ensure all electrical power is off. Installing and
wiring with active electrical power may result in serious injury
or death.
• Only install the smart dimmer switch if you are comfortable
with electrical work. If not, contact a qualified electrician.
Improper installation significantly increases the risk of fire,
electric shock, and other injuries.
• The smart dimmer switch must be installed and used in
accordance with the National Electric Code (NEC) or your
local electrical code.
• Do not install the smart dimmer switch with wet hands or
when standing on wet or damp surfaces.
Safety Information
Note: Etekcity cannot guarantee the quality of installation,
and cannot cover associated costs.

General Safety
• CAUTION: FOR CONTROL OF INCANDESCENT, HALOGEN,
CFL, OR LED LUMINAIRES ONLY.
• Only use indoors, in a dry location with ambient temperature
controls, avoiding extreme heat and freezing temperatures.
• Do not modify the smart dimmer switch hardware or
software. This may cause injury or property damage, and will
void the warranty.
• Household use only.

Installation
What You’ll Need
CAUTION:
• Only install the smart dimmer switch if you are familiar and
comfortable with electrical work. If not, contact a qualified
electrician. Improper installation significantly increases the
risk of fire, electric shock, injuries, or even death.
• Wear insulated gloves while installing the smart dimmer
switch.
• Non-contact voltage tester
• Wire nuts (twist-on wire connectors)
• Pliers
• Philips-head screwdriver
• Flathead screwdriver
• Insulated gloves

13
Checking Wires
1. Use the voltage tester to test a powered electrical cable to
make sure the voltage tester is working. If the voltage tester
lights up, it’s working.
2. To avoid electric shock, TURN OFF THE POWER by turning
off the circuit breaker before installation.
Note: You may need to shut off more than 1 circuit breaker or
switch to make sure the power is off.
3. Unscrew and remove the faceplate from the old switch.
4. Use the voltage tester to test around the old switch to make
sure that the power is OFF. Flip your switch on and off a few
times to confirm. The voltage tester should not light up, and
the light should not turn on.
5. Unscrew and pull out the old switch (without detaching the
wires).
6. Check to see if there are 4 wires connected to your old
switch. These wires are the ground, load, line (or “live”),
and neutral wires. If you do not see at least 4 wires in
the junction box, the smart dimmer switch may not be
compatible with that junction box. You can check other
switches in your home to see if there are compatible junction
boxes.

About the Wires
Load
• This wire connects the dimmer switch to appliances.
This is the wire that the smart dimmer switch
controls. All switches have a load wire.
Line (“Live”)
• This wire brings electricity to the dimmer switch. All
switches have a line wire.
CAUTION: Never twine the load wire and the line wire together
or connect them both to power. Only the line wire should be
connected to power.
Neutral
• Some old switches do not have a neutral wire.
However, a neutral wire is required to install the
smart dimmer switch. This is because the smart
dimmer switch needs to be powered on at all times
to operate.
• If you cannot find a neutral wire in your junction box,
contact a qualified electrician to rewire the switch.
CAUTION: Never connect the neutral wire with any other
wire. This can cause circuit abnormalities or burn out the
dimmer switch.

16
Ground
• A ground wire is not required for the smart dimmer
switch to work, as not all switches need ground wires.
• However, if a ground wire is present, it must be
connected to the smart dimmer switch.
Wire Nuts
• These are the cap-like objects connecting wires
together, also known as twist-on wire connectors.

17
Removing the Old Light Switch
1. After taking off the faceplate and checking the wires, use the
voltage tester again to test for any current around the wires.
2. Unscrew a wire from the old light switch. Use pliers to
straighten the wire. Then, screw a wire nut onto that wire.
3. Follow the same steps for the other 3 wires.

18
Installing the Smart Dimmer Switch
1. Make sure you understand the 4 wires on your smart
dimmer switch and the wires inside the junction box. Check
the labels on the switch next to each wire.
Note: There will often be 2 neutral wires already connected
by a wire nut. Connect all the neutral wires together with 1
wire nut.
3. For extra safety, wrap electrical tape around the wires to
make sure the copper conductor is fully concealed.
2. Connect the white wire to the neutral wire, which is usually
white as well, by screwing a wire nut tightly around the 2
wires.

4. Connect the green wire to the ground wire, which is also
usually green.
5. Connect the black line wire to the line wire, which is usually
black or red.
6. Connect the red load wire to the load wire, which may be any
color except green.
7. Push the wires and the wire nuts back into the junction box.
8. Attach the dimmer switch to the wall by screwing in the
mounting screws.
9. Snap the smart dimmer switch faceplate on tightly.
10. Turn power back on at the circuit breaker, then test the
dimmer switch by turning it on.
