Physical Installation
NOTE: The following illustrations are based on home wiring that follows the most current wiring code standards. It is possible that the wiring in your home will not match the color or number of wires as shown in the photos. Read all instructions carefully while installing.
Step 1: Turn OFF the power
Turn OFF the power at your breaker panel or fuse panel to the circuit where the Wemo Dimmer WDS070 will be installed.

Step 2: Remove Existing Light Switch
Pull out the existing light switch from the gang box. Do not disconnect any wires at this time.

Step 3: Identify Wires in the Gang Box
Check for the wires in your gang box. If your wiring is up to code, you may see the following:
- Two black wires connected to the light switch: one is the incoming (HOT) power from your electrical panel, and the other is connected to your lights (LOAD).
- Two white wires connected to each other (NEUTRAL).
- A copper-colored or green wire (GROUND). This wire may or may not be connected to your existing light switch.
IMPORTANT: The wire colors described are based on current wiring code standards. Your home's wiring may differ in color or number of wires. If you are unsure about the function of any wires, contact a licensed electrician.
For basic installation of the Wemo Dimmer WDS070, the following wires are required:
- Incoming (HOT) power wire from your electrical panel
- Outgoing (LOAD) wire to your lights
The NEUTRAL and GROUND wires are not required for installation but are highly recommended to connect for safety if available.
Step 4: Disconnect Existing Switch
Remove the wires from the existing light switch.
Step 4: Remove Faceplate
Remove the faceplate from the front of your Wemo Dimmer WDS070.

Step 5: Loosen Terminal Screws
Loosen the color-coded terminal screws on the sides of the light switch. Only loosen the screws for the wires you will be connecting.
Step 6: Connect Wires to Wemo Dimmer
Connect the wires to the Wemo Dimmer WDS070 using your preferred connection method.
(A) Insert into holes: Insert the wire end into one of the holes near the screw. Use a screwdriver to tightly screw the terminal screws back in, clamping down on the wire.
(B) Hook around screw: Use pliers to bend the end of the wire clockwise. Hook it around the screw. Use a screwdriver to tightly screw the terminal screws back in.
Illustration showing two methods for connecting wires to terminal screws: inserting the wire directly into a hole and hooking the wire around the screw.
IMPORTANT: Allow at least 9/32 inches of exposed wire when connecting.
Connect the Load and Line wires directly to their designated holes or screw terminals on the Wemo Dimmer WDS070 and tighten the screws.

It is recommended to use a pigtail wire when connecting ground or neutral wires. Connect the pigtail to the ground or neutral wire using a wire nut, then connect the other end to the designated terminal on the Wemo Dimmer WDS070.

Step 7: Tuck Wires and Mount Dimmer
Tuck the wires back into your gang box and screw the Wemo Dimmer WDS070 into the wall.

NOTE: Per Underwriter Laboratories (UL) regulations, it is recommended that screws be tightened to 1.2 Newton Meters (1.2 Nm) of torque force.
Step 8: Restore Power
Return to your fuse panel or breaker box and turn ON the power back to the circuit the Wemo Dimmer WDS070 is connected to.
