Wiring one switch

The following instructions cover installation of a single-pole installation (one switch wired to a fixture). If you are replacing two or more switches that control a fixture, follow the instructions for 3-way or other multi-way wiring.

Prepare your setup

  • Take advantage of daylight – you will need to disconnect power for installation, so we suggest doing the installation during the day to avoid having to work in the dark.
  • Get your tools ready
  • Screwdrivers:
  • Phillips head
  • Flathead
  • Voltage detector
  • Optional:
  • Wire strippers – in case you encounter wires that need pruning.
  • Painter's tape – you may wish to mask off the area below your switches, so your walls are kept clean.
  • Flashlight – your phone’s flashlight could do the job.
  • A friend or family member – it’s always good to have a helper.
  • Confirm compatible load
    The Nokia Smart Lighting Dial, Paddle and Keypad feature two operational modes: dimmer and on/off. The default setting for the Dial and Keypad is dimmer mode. The Paddle default setting is on/off mode. Use the table below to determine which mode you should be using with your fixture and if the fixtures are within the operating range:
Dimmer ModeOn/Off mode
Non-Dimmable LEDNot recommended150 Watts
Dimmable LED150 Watts
Incandescent/Halogen400 Watts1000 Watts
Ceiling or Exhaust FansNot recommended1/3 HP

Note: the Nokia Smart Lighting switches are not designed to be wired to an outlet (i.e., half hot receptacle).

Dial, Paddle, Keypad

These instructions apply to wiring of a Dial, Paddle, or Keypad in a single-pole application.

Remove old switch

  • Take advantage of daylight – you will need to disconnect power for installation, so we suggest doing the installation during the day to avoid having to work in the dark.
  • Get your tools ready
  • Remove the mounting screws and pull switch away from wall (leave wires connected for now).
  • Look in the junction box behind the switch to see if you have neutral wires. These are typically 2 or more white wires connected with a wire nut. Do you see them?
  • No: A neutral wire is required to use the Nokia Smart Lighting switches. Learn more about neutral wires and how to check if you have them.
  • Yes: Great! Let’s keep going.
  • 5. Remove the wires from the old switch – these wires are sometimes connected by screws or by wire nuts. If wires are pushed into the back of the switches, use wire cutters to remove.
  • 6. Use wire strippers to straighten the ends if bent and ensure you have ½ inch of exposed copper wire.
  • 7. Screw wire nuts over the wires using the wire nuts included with the new switch.
  • 8. Turn on power to the switch at the breaker panel.
  • 9. Back at the switch location, use a voltage detector to determine which of the wires is Line (powered) – use tape to mark wire as Line. Mark the other wire as Load (fixture).
  • 10. Turn off power to the switch at the breaker panel.

Install new switch

  • Connect the green ground wire from the new switch to the ground wires in the wall box. These are typically bundled in the back of the switch box and are bare copper wires.
  • Connect the white neutral wire on the new switch to the bundle of neutral wires.
  • Connect the red load wire on the new switch to the load wire.
  • Connect the black line wire on the new switch to the line wire.
  • Gently tug on the wires connected to wire nuts to make sure they are secure. Also make sure there is no exposed copper wire.
  • Tuck the wires back into the wall box and move the switch into position:
  • Dial: LED indicator facing upward.
  • Paddle: LED indicator on left side.
  • Keypad: LED indicators on right side.
  • 7. Tighten the switch mounting screws and make sure it is properly aligned with the wall box or other switches if installed in a multi-switch box.
  • 8. Return to your breaker panel and turn on the power.


Test that the switch is working properly:

  • Dial: Rotate the dial to dim and brighten*. Push to turn off and on.
  • Paddle: Tap the top to turn on, bottom to turn off.
  • Keypad: Tap the 4th button from the top to turn off and on (press and hold to dim/brighten*).

* If your bulbs dim and brighten without any issues, great! If your lights flicker or otherwise are not performing as expected, you have a few options:

  • Ensure your bulbs are dimmable. This is typically marked on the bulb itself, otherwise look for a make or model number and search online for information.
  • If the bulbs are dimmable but still do not perform well (flicker, flashing) consider adding the Nokia Smart Lighting Bridge and use the app to calibrate the dimmer.
  • Change the switch to on/off mode.

Install the wall plate

While Nokia Smart Lighting switches and outlets are designed to work with standard paddle-style wall plates, for best results use Nokia Smart Lighting Wall Plates. In addition to matching both the color and finish of your switch, they feature a screwless top plate for a pure and simple look.

If you are installing the Nokia Smart Lighting Dial in a single gang location, we recommend using the Nokia Smart Lighting Dial Wall Plate.
