How do I check my ground wire?

Wyze Switch does not require a ground wire, but it is safer to use ground wiring with any switch. The ground wire gives excess electrical charges a safe place to go. If your house was built in the 1960s or later, you should have a ground wire. 

💡 While you do not need a ground wire, you must have a neutral wire for Wyze Switch.

To check your ground wire, open your switch box:

If you are unsure whether or not you have a ground wire, look at your switch box, the metal box on the back of your light switch. Please observe all safety precautions before handling the electrical wiring in your switch boxes. If you are not comfortable or familiar with electrical wiring, we recommend consulting a licensed electrician.

Tools you will need: Flat-head screwdriver

  1. Turn off power at the circuit breaker for the switch you are going to replace.

  2. Confirm there is no power to the circuit by turning the switch on/off (there should be no power at all).

  3. Remove the wall plate of the existing switch by either snapping it off or unscrewing it.

  4. Unscrew the existing switch from the electrical box and slowly pull it out just enough to reveal the wires connected to it.

  5. Do not remove any of the wires from the existing switch. Take a photo of your existing wiring for reference.

  6. If you see a green or copper wire then you have ground wiring in your house. There should be four wires connected to your existing switch.

    1. Black/Red Wire (Load) - This is usually black/red in color. It goes from one terminal on your existing switch to your light fixture.

    2. Black wire (Line) - This wire comes out of your junction box and goes into a terminal on your existing switch.

    3. White wire (Neutral) - This wire is usually white in color and connects the neutral wires from your light fixture, junction box and existing switch.

    4. Green or Copper wire (Ground) - This wire is usually green in color or bare copper. It comes out of your junction box and connects to a terminal on the switch. This may not be present in older houses.

  7. Place the switch back into the junction box and mount all screws just the way it was. Make sure all wires fit will into the switch box. After mounting the switch to the wall box place the wall plate back on it and secure it with the screws.

  8. Turn on power at your circuit breaker and check if power at the switch is back.

If you are still unsure whether or not your house has a ground wire, please consult a licensed electrician for assistance.
