  • No neutral wire in your home? No problem

    This High-Wattage Dimmer is for you and installs like the traditional Dimmer Wall Switch with the exception of requiring a connection to a neutral. Once installed, setup is quick and easy using simple programming.

    RF Wireless Signal Only

    Older homes without neutral wires are not excluded from home automation. This 2-wire Dimmer Switch transmits wireless signals only to never limit the expansion of your Insteon network.

    Remote Control

    Insteon Wall Switches can be remotely controlled from almost any device in your home: Sensors monitoring doors, windows, leaks and more, remotes, keypads and other wall switches throughout your home, even your smartphone when used with the Insteon Hub.


    One of the most powerful features of Insteon switches, Scenes let you control multiple devices simultaneously with a single tap. Brighten all of the lights in an entire room with a tap-and-hold or create infinite virtual multi-way switches.


    No wall switch is more customizable. Change the paddle color to suit your décor needs. Swap out the LED light pipe for personalized colors. You can even custom-etch text onto the switch paddles for ease-of-use in multi-gang switch boxes.

    Control on Apple Watch

    With the Insteon App on Apple Watch, control of your Insteon Wall Switch is never out of reach. Pick from one of four presets for Dimmer Switches.

    Remote control with Insteon sensors

    Your Insteon Wall Switch can do so much more when given access to the family of Insteon sensors. With a few taps of the set button or a moment's time with your smartphone, you can configure sensors throughout your home to automatically turn on (or off) the lights based on a variety of different actions.


    There are some rooms in your home that, no matter what time of day, you always end up turning on the lights: Pantries, closets, hallways, etc. With an Insteon Wall Switch and an Open/Close Sensor (or Hidden Door Sensor), you will never need to turn the light on again. And better yet, you'll never need to remember to turn it off.

    Motion & Occupancy

    Do you play whack-a-mole all day, turning off the lights in rooms that your significant other or children have habitually left on? Turn every Insteon Wall Switch into an occupancy-sensing switch with an Insteon Motion Sensor. And with Insteon, your Motion Sensor can control multiple Wall Switches simultaneously for large rooms or long hallways.

    No one wants to think about the potential for a disaster, but if one were to happen, make your escape as safe as possible by automatically turning on lights to an escape path when Smoke Bridge detects smoke, fire or carbon monoxide from a linked First Alert OneLink detector.

    Garage Door

    It's no only cool, it's handy too. Whenever you open your garage door, turn on the overhead lights for easier entry and exit from your vehicle. And while you're at it, turn the outside sconces and walkway lights on, too for that extra bit of illuminated peace-of-mind when you come home late at night.

    Cases for your Switches

    You've got this fancy new remote-controllable Wall Switch, so why blemish it with that old chipped and discolored wall plate? Insteon Wall Plates add that extra bit of frame and polish. Oh - and they are screwless, so all you see is your fantastic new switch.

    Can be made to work with LED lights Review by Albert
    Can be made to work with LED lights

    For those who have trouble getting it to work with LED lights (ie. flashing issues, flickering, not going completely off, cycling, etc.), you can add a small 4W incandescent night light (manual switching, not photoLED switched) to the switch and it will work properly.

    1 bad and 2 good Review by ctg023
    1 bad and 2 good

    I bought 3 of these recently. After a week one of them started to smoke, so I disconnected it (must be a bad controller inside) and I"m currently waiting for a replacement. I had to hard reset a 2nd after it was unresponsive, and the 3rd one is working as expected, but it only been a little over a week. I've had the best luck with the outlet dimmers for my lamps.

    CFL dimmable? Review by Luis
    CFL dimmable?

    Easy to install. However can this control dimmable CFL bulbs? LED's?

    Smarthome reply: Insteon 2-Wire Dimmer is for use with incandescent bulbs only.

    Outstanding - Works Great Review by Markee
    Outstanding - Works Great

    After ordering the 3 wire units and returning them to get this two wire unit, they work great. Controlling my outside lights at sunrise and sunset automatically from the Hub... Far superior to the old erratic X10 system that they replace. Love the ramp up action, and they are probably easier on the filaments (less surge current when turned on) and the bulbs will last longer... So glad Smarthome is here to help :o)

    The first one was bad and kept cycling on and off. I returned it and the new one seems to work fine.

    Review of 2474DWH

    I installed this two wire switch in a room with a fan and light. I wired it into the light portion which has LED lights in it. It works perfectly dimming, on, off, etc. Sorry Ronald couldn't make it work.

    Review of 2474DWH

    This one of dozens of Insteon products that I have bought over the years. This was needed because of a two wire configuration at a BBQ island. Worked great.
