  • Turn Any Wall Switch Into an Insteon Remote Controllable Switch

    Micro On/Off Module keeps your existing antique, toggle or decorative wall switches while adding the customizable, dimmable remote control
    functionality of an On/Off Wall Switch.

    Discreet Installation

    Micro Modules keeps your antique, toggle or decorative wall switches by installing behind your existing switch. Due to its hidden nature, we highly recommend Insteon app with Insteon Hub to manage Micro On/Off.

    Remote Control

    Sometimes the couch is just too comfy and that wall switch is just too far away. Grab your smartphone and brighten and dim your switch to your heart's content.


    Automatically turn your porch lights on at dusk. Wake up to a gentle pseudo-sunrise at 7AM. You can schedule individual wall switches or full groups of switches for particular hours and days of the week.


    With the Insteon Hub, scenes really take on a new level. Program one switch to turn off all of the downstairs lights. Configure another to turn on Movie Mode. And because you can schedule scenes, you can give your home that "lived in" look even when you're away.

    Remote control with Insteon sensors.

    Your Insteon Micro Modules 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 Micro Module 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 Micro Module into an occupancy-sensing switch with an Insteon Motion Sensor. And with Insteon, your Motion Sensor can control multiple Micro Modules 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.

    Nice Review by Colby

    I have installed ten of these. They all work perfectly and are nice and small.

    Be sure to take note of their ID before putting them inside a wall.

    Working as expected as in an HVAC system Review by Luke
    Working as expected as in an HVAC system

    I am using this to control an HVAC booster fan along with a wireless thermostat. The system works well.

    - Small
    - LED makes troubleshooting easy

    Other thoughts:
    - Be careful when using this with the HouseLinc since HouseLinc tends to revert some of the settings (like switching the device back into three-way mode)

    No bueno Review by spatrick
    No bueno

    Unfortunately the 'Add remote control to virtually any switch or outlet' didn't hold true to 2 wire installations. Finding out it will not work in my case and no option to get the same deal on a 4 pack for the switch that would work (even though same unit price). Returning...

    Awesome Review by Joe

    Our rear porch light was separate from our Front porch light and lights next to garage doors. Front lights on a 3 way with a switch inside garage. I always thought why didn't they use a four way switch to control all lights. We built a detached garage and I had those light on a timer. After reading reviews I decided to take the plunge. I wanted to keep the toggle switches so I used the Micro Modules. The first switch I hooked up was rear door to garage. They would not link. I called tech support and was told the sub panel and brick wall must be blocking both signals. Luckily I had a extra conduit buried that still had the wires I used to get temporary power to garage while building it. I ran that to a junction box inside detached garage. I eliminated the switch inside detached garage door and used the Micro module as the switch. Never used a switch before anyway. I can always add a remote later. Wow it worked. I must have turned lights on and off a dozen times and giggled every time.
    Ok, now onto the three way at front porch and inside garage doors. I opened the cover at front door. Wow what's the extra red wire. I checked box inside garage and it had the white wire with black tape on it along with red. That made sense, but the extra red inside at front door had me confused. I decided to call an electrician. He never called back. So after a night of restless sleep I looked deeper into box and saw a black capped wire?? Ahh, the red must be hot going to outlet on porch. I made white wire common and eliminated a traveler to the other switch just as in video. Hooked both Micro modules and linked all to be transponder and receivers. This is AWESOME. I can now control all my outdoor lights from one switch.
    BTW I tested another Micro module in in the garage and now that one is working it links even with the sub panel.

    Great multi purpose device Review by Patrick
    Great multi purpose device

    I just installed this great little device in my over head range. This is being used as part of my HVAC solution which is being controlled by my ISY-994.

    When the temperature gets too hot the controller activates the Micro On/Off module to come on for a specified duration. It has been working great for several months and I look forward to integrating more of these in the future.

    PRO'S: Small & compact, versatile, dual band, sense wire.

    CON'S: Sense wires are too thin and needs to be upgraded. Device needs mounting tabs / ears. Price, this device should really be in the $25.XX range.

    Review of 2443-222

    Work as expected. Fit behind two outlets nicely for my backyard motion lighting project. I have 4 RAB Stealth motion lights connected in series. The On/Off module is always on allowing the motions to work as intended. Where the On/Off comes into play is when I want to keep the lights on manually by turning on my patio Switchlinc switch. That runs a program to turn the On/Off module off/on/off/on within two seconds to trigger manual mode on the lights. When I tuen the patio Switchlinc off, the On/Off module goes off for 10 seconds then back to putting the motions back into "auto". Couldn't be happier.

    Review of 2443-222

    I installed the 2442-222 Micro On/Off relay into my over head range to control the fan. This will be used as part of my HVAC solution to control and maintain the homes ambient temperature and humidity.

    The device will be controlled using the ISY-994iZ HA controller from UDI. The system works perfectly and the 2442-222 is a stellar product.

    The device is small and has a great form factor but should have mounting holes so it can be screwed in or wired tied for various installs. For my install I used double sided 3M tape to affix the unit. I will be buying many more of these devices as they are a great solution to deploy Insteon control in the home.
