A 3 way dimmer module controls a light from two locations and adjusts brightness, ideal for large rooms or hallways. It replaces one standard switch in a 3-way circuit and comes in traditional and smart versions for versatile lighting control.
A 3 way dimmer replaces one of two standard switches controlling a single light. It uses a common wire to bring power, traveler wires to communicate between switches, and a load wire sending power to the fixture. Traditional dimmers adjust brightness at one switch, while the second switch controls on/off without dimming.
These wires form the basis of 3-way switch circuits:
| Wire Type | Function |
|---|---|
| Common Wire | Carries power from the panel to switch |
| Traveler Wires | Connect two switches for communication |
| Load Wire | Carries power from switch to light fixture |
A traditional dimmer only dims at the master switch, while a smart dimmer allows both locations to adjust brightness seamlessly.
Traditional 3-way dimmers allow dimming control at only one switch and use basic wiring. Smart 3-way dimmers include a master dimmer and one or more companion switches that communicate wirelessly or via traveler wires, enabling full dimming control at each location.
Key differences:
Traditional dimmer: One dimmer switch, second switch only on/off.
Smart dimmer: Master dimmer plus wireless or wired companion switches.
Smart dimmers enable app and voice assistant integration.
Repenic offers smart Zigbee dimmer switches designed to install easily without a neutral wire, compatible with most UK homes, supporting dimmable LEDs and halogens but not smart bulbs.
Before installation, always shut off power at the breaker panel and verify with a voltage tester. Identify the common, traveler, and ground wires on the old switch.
Installation steps:
Disconnect the old switch where the dimmer will go.
Connect the common wire to the dimmer’s black screw.
Connect the two traveler wires to the brass screws.
Connect the ground wire to the green terminal.
Leave the other switch as a standard 3-way on/off switch.
Traditional dimmers are not built to work in pairs, so only one dimmer switch is installed per 3-way circuit.
A smart 3-way dimmer replaces one switch with a master dimmer and the other with a companion switch or remote. The master connects to Wi-Fi to enable app and voice control. Installation varies by brand but typically includes:
Replacing one switch with the master dimmer.
Replacing the other with a companion switch.
Downloading the manufacturer’s app (such as Repenic’s) to connect devices to Wi-Fi.
Configuring voice assistant integration like Alexa or Google Home.
Repenic’s Zigbee dimmers provide stable indoor communication over 30 meters, and their clean designs include metal faceplate options.
A 3 way dimmer module enhances convenience by allowing brightness control from multiple locations, improving home ambiance, saving energy, and extending bulb life. Smart versions add advanced features like remote app control, scheduling, and voice commands.
Benefits include:
Convenience: Control lights from two points.

Avoid 3-way dimmers if:
Your lighting uses CFL or fluorescent bulbs (traditional dimmers are incompatible).
You have smart bulbs that require dedicated wireless apps.
Your home wiring is not standard 3-way.
You prefer single-location dimming or manual switches.
Repenic’s dimmers specifically exclude CFL/fluorescent compatibility and smart bulb integration.

Common issues include flickering lights, dimmer incompatibility, and wiring errors.
Solutions:
Ensure bulbs are dimmer-compatible LEDs or incandescents.
Confirm proper wiring of common and traveler wires.
Use Repenic products to avoid neutral wire issues.
For smart dimmers, verify Wi-Fi and Zigbee signal strength.
Proper selection and installation of Repenic dimmers minimize typical faults.
Yes, dimmers reduce energy consumption by lowering light output. Dimming incandescent and halogen bulbs reduces wattage proportionally. LED dimmable lights also save electricity though less dramatically.
Dimming extends bulb life and supports energy-saving goals, especially combined with smart schedules or remote controls, as with Repenic’s app-enabled dimmers.
To prolong your dimmer’s life:
Use bulbs compatible with the dimmer’s specifications.
Avoid overloading the dimmer beyond rated wattage.
Follow installation instructions precisely.
Keep dimmer units clean and dry.
Repenic’s durable metal and plastic construction ensures reliability in typical home environments.
