Choosing Your Smart Light Switch
With a basic understanding of smart switches, let’s look at what options you have to choose from when purchasing your smart light switch or dimmer.
Switch vs. Dimmer Model
Standard smart light switches simply turn lights on and off – perfect for non-dimmable lighting circuits. Smart dimmers allow you to vary the brightness levels of dimmable bulbs, which is excellent for ambiance controls. Ensure you choose dimmable or non-dimmable models correctly based on your existing lighting.
Single Pole vs Multi Location
The most straightforward single-pole configuration has one switch controlling a light or circuit of lights. Multi-location circuits have multiple switch boxes controlling the same lights (e.g. stairs). Smart switch manufacturers offer different models depending on your switch wiring configuration.
With the above factors in mind, carefully review your requirements and features before purchasing your smart light switch.
Preparing to Install Smart Light Switch
Once you’ve selected the right smart switch product, we’re ready to dive into the installation process. Follow these preliminary steps to ensure you are fully prepared:
Step 1: Turn Off Power
Begin by switching the circuit breaker at your main electrical panel for the switch off to ensure the wires are not live. Test wires with a non-contact voltage tester before proceeding, just in case.
Step 2: Remove Existing Light Switch
Make sure to take photos of your wiring configuration before removing it! Then unscrew and gently remove the old switch from the electrical box in the wall.
Step 3: Clean Electrical Box
Use a vacuum with brush attachment followed by a clean rag to remove any dirt or dust from the now-exposed electrical box where you’ll be installing new wiring connections.
With safety and preparation steps complete, we can now move on to wiring and mounting the new smart light switch!
How to Wire Smart Light Switch
Let’s get into the details about properly connecting smart light switch wires during the installation process:
Identify Your Home’s Wiring
There are a few general wiring scenarios you’ll encounter when replacing a light switch:
2-Wire Cable
This is the most basic, with just a live/hot wire connected to switch and neutral wire. No ground wire is present in box.
3-Wire Cable
Consists of live/hot wire, neutral wire, and bare copper or green ground wire.
Backstab Wiring
Here side/back holes allow wires to be pushed directly into switch body without screws.
Carefully note your home’s wiring colors and setup before proceeding!
Connect Switch Wires
Now that you’ve identified existing wiring follow manufacturer instructions to connect the correct smart switch wires to matching home cables:
– Line Wire – Live wire from power source (matches former switch cable)
– Load Wire – Wire that runs to light fixture (matches former switch cable)
– Neutral Wire – Typically white neutral from power source
– Ground Wire – Bare copper or green wire
– Traveler Wires [3-Way Switches] – Allow communication between multi-location switches
Use twist-on wire connectors to connect exposed ends of each conductor cable securely.
Install into Wall Box
With all wiring complete, gently place connected smart switch into wall box without bending or damaging wires. Then screw molded ears on sides of smart switch into place, securing it inside the box.
Finish Smart Switch Installation
After installing and wiring the smart light switch itself, a few final steps complete the installation:
Step 1: Double Check Connections
Verify wire connectors to switch connections are tightly secured with no exposed metal. Also, confirm no loose wiring could touch each other causing dangerous shorts.
Step 2: Clean Up Wires
Make sure wiring is neatly coiled inside wall box so that the smart switch and wall plate fit and mount correctly without pinching wires.
Step 3: Attach Wall Plate
Align wall plate over protruding smart switch and securely screw it into place. The wall plate neatly hides wiring and gives the switch a clean, professional appearance.
Step 4: Restore Power
Head back to electrical panel and switch the appropriate circuit breaker back “On” to provide power to the new switch and light circuit.
Step 5: Connect Switch to WiFi
The final step is connecting to the smart switch from your home WiFi using the product’s companion app following the on-screen setup process.
Once connected, you’ll be able to control and automate your lighting from smartphones anywhere and through voice assistants!
3-Way Switch Installation
The connection process differs slightly when installing smart switch models designed to replace and connect multiple 3-way style switches that control the same lights.
Here is a quick overview:
Use Companion or Traveler Switch
Purchase a compatible add-on smart switch, or basic companion switch for 3-way circuits. This allows you to retain multi-location control.
Identify Traveler Wires
Note wires connecting the two existing 3-way switches (typically black and red). These are called traveler wires.
Connect Traveler Wires
Attach traveler wires to corresponding traveler wire terminals on smart switch and companion switch to enable communication.
With the above specifics for 3-way wiring configurations, be sure to always follow the detailed product instructions for traveler wire connections unique to your smart switches.
Smart Switch Installation Tips
To ensure your smart switch installation goes smoothly, keep these tips in mind:
- Safety First – Make absolutely certain power is OFF before touching any wiring. Double-check with non-contact voltage tester.
