Setup instructions

WARNING! Risk of electric shock

Incorrect installation could be dangerous or illegal. You might need to turn off multiple breakers/fuses for safe installation. Please call a professional electrician if you are unfamiliar or uncomfortable with electrical work

1. Turn off the power
   1. Shut off power to the switch you’re replacing at your fuse panel or circuit breaker
      Confirm that power is off
      1. Remove the cover plate from the existing switch.
      2. Use a voltage tester to test BOTH sides of the switch. You may need to turn off more than one circuit breaker/fuse
2. Pull out existing switch
   1. Unscrew the switch and gently pull it out of the wall.
   2. Do not remove any of the wires yet
      Pro Tip:
      Take a picture of the wires in your wall to refer back to later
3. Look for NEUTRAL wires
   NEUTRAL wires are usually white. If you have them, we will direct you to connect them later in step 7. If you don’t have them, your house is not compatible with Wemo Smart Light Switch.
   Note:
   You may have a different number of neutral wires than shown.
   Test the NEUTRAL wires
   Use a voltage tester to check that there is no power in the NEUTRAL wires from neighboring circuits. If necessary, shut off additional circuits until no voltage is found
4. Identify your existing switch
   Single pole
   If one switch controls one light, it is a single-pole switch
   3-way
   If two switches control the same light, they are both 3-way switches
   4-way
   If three switches control the same light, the one with 5 screws is a 4-way switch. The other two are 3-way switches.
   Follow 3-way installation instructions
   Wemo Smart Light Switch cannot replace a 4-way switch
5. Remove existing switch
   Disconnect the LINE and LOAD wires (usually black) from the existing light switch.
   Note: Your existing switch, wires, and electrical box may look different and have different colors
   Disconnect the GROUND wire from the switch (usually bare copper or green). Remove wire nuts from the white NEUTRAL wires
   
6. Prepare Wemo Smart Light Switch and wires
   Grab the cover plate from the top and pull down to snap it off of the Wemo Smart Light Switch
   Loosen the black and red screws on the Wemo Smart Light Switch with a screwdriver.
   Options for connecting wires
   1. Insert into holes
      1. Insert the wire end into either of the holes near the screw.
      2. Use a screwdriver to tightly screw the terminal screws back in. These will clamp down on the wire.
   2. Hook around screw
      1. Use pliers to bend the end of the wire clockwise. Hook it around the screw
      2. Use a screwdriver to tightly screw the terminal screws back in
         For the upcoming steps, choose your preferred option for connecting wires:
         Note:
         If needed, use pliers to strip the wire end to this length:
7. Connect LINE, LOAD, GROUND, and NEUTRAL wires
   1. Connect the LINE and LOAD wires from the wall (usually black) to the black and red screws on the light switch using your preferred method ( shown here).
      Tighten each screw after inserting wire
      Note:
      Either wire can be connected to either screw.
      Connect the GROUND wires (usually bare copper or green) from the wall to the green screw on the switch
      Connect the provided jumper wire from the silver screw on the light switch to the NEUTRAL wires in the wall with a wire nut
8. Install Wemo Smart Light Switch into the wall
   Almost done! Tug each wire to ensure they are securely connected
   Carefully tuck the wires behind the switch and into the box. Screw the light switch into the wall. Be careful not to over-tighten the screws
   Pro Tip
   Make sure to insulate any exposed wiring with electrical tape
   Before snapping on the cover plate, you’ll notice an 8-digit setup code on the switch. You may need this during app setup. You can also find it in step 10 of this guide
   Finally, snap the cover plate onto the switch
   
9. Turn on the power
   Turn on power to your switch at your fuse panel or circuit breaker panel you turned off earlier.
   Press the switch to put it in setup mode
   
   1. The light will blink blue when it is ready
10. Add to the Apple Home appUnlock your phone.
    1. Hold the upper back of your phone at the center of the switch
    2. Adjust your phone angle until setup prompts appear on your phone
    3. Follow prompts

Thread for quicker and more reliable control

• Thread is a new wireless technology built into Wemo. It connects smart home devices more quickly and reliably than Bluetooth or Wi-Fi.
• To take advantage of it, you’ll need an Apple HomePod mini or the latest Apple TV 4K. If you don’t have one of those, your Wemo will connect using Bluetooth. Learn more at wemo.com/thread
