You’ll need electrical and handicraft tools to install a 3-way smart dimmer switch safely and efficiently. Before starting this project, ensure you have these tools:
- Voltage Tester: A non-contact voltage tester is needed to verify that the circuit you’re working on has no electrical current. This protects you before wiring.
- Screwdrivers: Flat-head and Phillips-head screwdrivers must remove, and attach screws on your switch plate and new dimmer switch.
- Wire Strippers: These instruments accurately remove electrical wire insulation for suitable connections.
- Wire nuts connect and insulate wires: They ensure secure connectivity.
- Needle-nose Pliers: These bend, twist, and grab wires, making installation easier.
- Circuit Tester: A circuit tester verifies that the circuit’s electricity is off, adding safety.
- Utility Knife: Cuts and trim wires and cables cleanly.
- Electrical tape: insulates wire connections and prevents accidental contact.
- Labeling wires: can help you track connections, especially in complex setups with many cables.
- Pencil and Notepad: Sketch the wiring layout or take notes during installation with a pencil and notepad.
- Step Ladder: A step ladder may be needed to reach the switch box, depending on its location safely.
- Safety gear: Protect yourself with safety glasses and clothes.
Remember to be careful and know what you do when working with power. If you need clarification on any part of the construction process, it’s best to talk to an electrician or other professional before moving forward. Your 3-way smart dimmer switch can be safely installed if you have the right tools and know how to install it.
In a lighting system with three separate switches, installing a 3-way smart dimmer switch requires replacing one of the pre-existing switches. To ensure that your installation goes off without a hitch, carefully follow these steps:
Step 1: Make Sure the Power Is Off
Find the circuit that controls the three-way switch in your service panel and turn off the breaker that controls it.
Checking both switches with the voltage detector will allow you to establish whether or not you have located the appropriate breaker.
Step 2: Determine Which Wires Are Black Terminals
After removing both switches from their respective boxes, you will notice that there are a total of four wire terminals.
Find the terminal on the switch labeled “common” with a black screw attached to it.
Put a piece of electrical tape over the end of the wire connected to the screw on each switch.
Step 3: Determine Which Wires Are Travelers
On each of the switches now in use, you will find two travelers linked to terminals opposite one another. These terminals typically have a color similar to brass, and the wires connected to them are usually black and red. However, this is only sometimes the case.
These wires should be identified as Traveler 1 and Traveler 2, respectively.
Use a Sharpie to make a distinct mark on one of them so that you can quickly tell them apart.
Step 4: Disconnect the Wires and Prepare Them
Take off all of the cables that are attached to your present switches.
The Leviton Smart switches require a straight wire cut back to a length of 5/8 in.
Re-route any wires that have been tangled and check to see that they have been stripped appropriately.
Tip: If you have more than three inches of wire protruding from your box, snip off any hooked wires and re-strip them to create a straight and clean wire end. This is only necessary if you have more than three inches of wire protruding from your box.
Step 5: Locate the line feed
After ensuring that the prepared wire ends are not contacting one another, turn on the breaker allocated for this purpose.
Cautiously utilize your voltage detector on each wire tagged with tape to determine which one is hot. This live wire serves as your line feed; at this point in the circuit is where you should install your primary smart switch.
Your load connection, which leads to the light fixture or outlet, is in the other box with the taped wire. This box is not considered to be hot.
Take note: This is where you should install the remote smart switch.
After you have located the line feed, the breaker should be turned off.
Step 6: Install the Primary Intelligent Switch
Look in the box containing the line feed for any white neutral wires spliced together now that the breaker has been switched off once more.
You will need to remove the wire connector before you can install the white jumper wire that is five inches long that came with your new smart switch.
After splicing together the three neutral wires, connect the other end of the jumper wire to the WH terminal on the switch. The BK terminal is where the line feed wire that is marked with tape is attached.
The YL/RD terminals and the RD terminals are the destinations for the two traveler wires.
Make a mental note of which traveler wire is connected to each of these terminals (for example, Traveller 1 is connected to YL/RD, and Traveller 2 is connected to RD, or vice versa).
When you are wiring the remote switch, you will need to know this information.
To finish the wiring of the main switch, connect the ground wire to the terminal that is colored green.
Step 7: Installing the Remote Switch
Again, hook a jumper wire from the white cables spliced to the WH terminal on the remote switch. Do this in the box that contains your load connection.
Note that the traveler previously connected to the YL/RD terminal on the main switch will now be connected to the YL/RD terminal identically positioned on the remote button.
The traveler attached to the RD terminal on the main switch is then spliced together with the load wire marked with tape in this box. The final step is to turn the power back on.
On this remote switch, the BK and RD terminals that are still present are not connected to anything; they are there to accommodate a variety of uses for the control.
At long last, connect the ground wire to the terminal that is green in color.
Step 8: Tape Terminals
Wrapping your rewired switch with electrical tape will prevent any arcing from occurring between the bare terminals and the ground cables or metal boxes.
When reinstalling the switch, be sure to tuck the wires within the box carefully.
Step 9: Confirm That the Manual Operation Is Working
After manually operating the switches after you check your installation, you should turn the power back on.
Before connecting to WiFi and utilizing the Phone app, it is in your best interest to confirm that regular operation has been resumed.
10th Step: Connect to a WiFi Network
Download the app after first connecting your mobile device, be it a phone or a tablet, to the same WiFi network that your smart switch will be running on.
To set up the whole wireless operation of your three-way switch, you must follow the directions provided within the app.
A helpful hint is that most smart switches enable you to connect to smart speakers such as Alexa or Google Assistant, which allows you to derive even more value from a three-way smart control you’ve already placed.
How to Fix the Problem with the Flickering
If the light is flickering, you should check if any bulbs have come loose and ensure that each can be turned down to a lower level. If the flickering does not stop, the issue may be due to surges or spikes in the electrical supply where you are located. By manually adjusting the lowest dimming point to the lowest dimming point, this issue will be resolved.
To manually adjust the brightness level to the lowest possible setting, press and hold the dim up and dim down buttons simultaneously for at least 5 seconds. This will bring about the desired effect. Once the power has been restored, the switch’s power indication circle will begin flashing.
You can select the lowest dimming level possible without seeing any flickering by using the buttons on the dimming control panel. The next step is to push and keep holding the dimming buttons for either five seconds to complete the setting or until the power indicator light changes from a circle to a solid light.
In a world where technology is a big part of everything we do, a 3-way smart light switch is a big step towards a smarter, more efficient home. From switches to app-controlled dimmers, we’ve always tried to find ways to make things easier, look better, and last longer.
By following the exact steps in this guide, you’ve entered the world of do-it-yourself home repairs and made your living places more adaptable to your mood and needs. Wiring and safety had to be done carefully during installation, but the rewards were great.
Imagine making great lighting for parties, relaxing, or working without getting up from your chair. Your house can be controlled by touch, voice, or your phone.
As you enjoy the dim lights, think about how far you’ve come from dealing with complicated wiring to add new technology to your home’s infrastructure easily.
