Installation Process: Which Is Easier?

Proper installation is crucial for any smart switch, especially when electrical wiring is involved.

Installing Lutron Caseta

Lutron Caseta is known for its user-friendly installation process, particularly because many models don’t require a neutral wire. This makes it a lifesaver for homes built before the 1980s.

Installation Steps Overview:

Turn off the circuit breaker.
Replace the existing switch with the Caseta dimmer.
Connect the line, load, ground, and (if available) neutral wires.
Set up the Lutron Smart Bridge and pair devices using the Lutron app.
Optional: Install the included Pico Remote for additional convenience.

Time Estimate: 30–45 minutes

Tip: If you have multiple switches controlling the same light (three-way setups), Lutron’s Pico remote can simplify the wiring dramatically.

Installing Kasa Smart Dimmer

Kasa Smart Dimmer switches are typically easy to install—provided your home has a neutral wire at the switch box.

Installation Steps Overview:

Turn off the power at the breaker panel.
Remove the existing switch and identify your wiring (line, load, ground, and neutral).
Connect the wires to the Kasa dimmer.
Follow the app-based instructions to connect the switch to Wi-Fi.
Customize settings via the Kasa app.

Time Estimate: 20–40 minutes

Important: If you don’t have a neutral wire, you may need an electrician or consider alternatives.
