Nano Dimmer. Simply make all your lights smart.

The 83% smaller in size and 100% reengineered. To create an upgrade this advanced, you have to start at the very beginning. And that’s what Aeotec has done with Nano Dimmer, the next-gen lighting controller. Nano Dimmer retrofits to any switch to make it a smart one.

Universally compatible with leading and trailing edge systems, and with all modern bulbs including dimmable LEDs, Nano Dimmer continues to offer everything that Aeotec pioneered in retrofit lighting control: reliable power metering function, and an installation time of less than 5 minutes.

The Aeotec Nano Dimmer will drastically improve your home lighting. It lets you convert any light dimmer switch into a Z-Wave Plus dimmer. You can control it, schedule it or automate it from your existing light switch or a Z-Wave gateway.  Aeotec Nano Dimmer is a Z-Wave smart dimmer device specifically used to enable Z-Wave command and control (on/off/dim) of any in-wall switches. It can report immediate wattage consumption or kWh energy usage over a period of time.

Nano Dimmer offers smart, connected lighting without any of the hassle and it retrofits to any switch to make it a smart one. Its fantastic dimming capabilities are complemented by super-accurate power metering, surge protection and overload protection. Nano Dimmer is compatible with all certified Z-Wave gateways including SmartThings, Fibaro and Vera. It will also work with Amazon Alexa when used with an Alexa compatible hub or gateway.

Simple installation

Nano Dimmer lets you add new and existing lights to your Z-Wave system. Now you can make your lights smarter, with the ability to control, schedule, dim and brighten them.

Nano Dimmer features with simple wiring behind your existing wall switch, so you don't have to change the look of your home.


The best wiring compatibility yet

The complex light bulb compatibility just became easier. Due to Lighting Engine and a dedicated 32-bit CPU that features Nano Dimmer, it calculates perfectly smooth dimming, perfect bulb compatibility and self-adjusting its settings whenever a new bulb is used.

You'll never have a problem with finding lights that works with Nano Dimmer’s list of compatible bulbs. Nano Dimmer's Lighting Engine can be upgraded, which means that new compatibility calculations are only a firmware upgrade away thanks to Nano DImmer's support Over The Air (OTA) feature for the products firmware upgrade.

Works with or without neutral

Beside its better lighting compatibility, Nano Dimme has a better wiring compatibility too. Whether your lights are installed in a 2-wire or 3-wire system, Nano Dimmer is compatible. Nano Dimmer will work with simple wiring or complex, 2 or 3-wire installations and Lighting Engine auto-detects whether your light switches have a neutral wire or not, then automatically adjusts it settings.

Keep your existing light switch

Nano Dimmer has been designed to work with most of the typically light switches - new or old. It  can invisibly be installed behind them, enchancing their functionality instead of completely replacing it.

Nano Dimmer can be connected to: Toggle switch, Rocker switch, Pull-chain switch, Push-button switch, Slider switch and Wall switch.


Works without any switch at all

Z-Wave Plus connectivity lets you to intelligently automate your Nano Dimmer. You can responsively control it, manage it and monitor it even when you’re not home. Isn't that great?

Smooth dimming even with its small size

Despite now being 60% smaller than Aeotec original technology, every single millimetre of Nano Dimmer benefits from Aeotec 10 year’s experience in making in-wall dimmers. That decade’s worth of expertise makes Nano Dimmer compact without compromise.

Create the perfect amount of light with Nano Dimmer. It can dim your lights from between 0% and 100%. And it can dim them at perfect speed offering an adjustable ramp rate allowing the brightness of your lights to be adjusted over moments or minutes.

Surge and overload protection

Surges happen and are common, but Nano Dimmer protects against them. With a in-built surge and overload protector, you will never have to worry again. Nano Dimmer not only keeps your lighting connected, it keeps them protected too.


Wireless update

Keep Nano Dimmer compatible and Lighting Engine up to date; Nano Dimmer’s firmware can be updated wirelessly.

Faster than ever

Your lighting should be quick and responsive. Nano Dimmer responds in milliseconds, changing your lights 250% quicker than past generations.


Nano Dimmer is built upon Aeotec’s leading Gen5 technology and is powered by the latest version of Z-Wave - Z-Wave Plus.

Perfect and smooth dimming

Nano Dimmer can be dimmed at 1% increments from 0% right through to 100% brightness. Nano Dimmer offers a customisable ramp rate so that it can dim or brighten as fast or as smooth as you want it to.

Fan control

Control your lights and control your ceiling fans. Nano Dimmer can be wired to turn select ceiling fans as powerful as 100 watts on and off, and control their speeds.

See your spend

Along with control and dimming, Nano Dimmer includes Aeotec’s energy metering technology for an accurate measurement of how much electricity your lights are spending.

Improved signal

A wireless signal that goes further, stronger. Nano Dimmer’s improved wireless technology is perfect for pass through walls now that it’s 2.5dBM stronger.

Lighting Engine

Homes have unique lighting and switches. From bulb type to switch type to wiring type to load type, Lighting Engine powers Nano Dimmer’s class-leading dimming compatibility.

1.5 amps

Small in size without compromise. Nano Dimmer can control lights and loads that draw up to 1.5 amps of power.


Perfect with low voltage lights

Homes increasingly have low energy lighting that is hard to dim. But not for Nano Dimmer. It can even dim low power LEDs and CFLs that use less than 20 watts through the use of a bypass for Nano Dimmer (sold separately).

Z-Wave Plus

The Z-Wave Aeotec Nano Dimmer is Z-Wave Plus Certified. Z-Wave Plus (5th Generation Z-Wave) offers a lot of new features including increased range, extended battery life and Over The Air upgrading (OTA). Take a look at our "What is Z-Wave Plus" guide for more information

Does the Aeotec Nano work with 3-Position Momentary Switch - S1, On and Up - S2 Off and Down
Peter K. 23 Oct 2017
Where is the Aeotec bypass? Aeotec's website still says that it will be available "early 2017", and yet here we are here in September and I cannot see much evidence of its availability. Does anyone have any insights into when it will be available? Thanks.
Chris S. 11 Sep 2017
Is the common connection a 3v output like the micro modules?
Jason P. 30 Jul 2017
When controlled by the local switch, can the level be controlled e.g. press briefly to turn on/off, press and hold to cycle the brightness?
Nigel E. 25 Jul 2017
how do these perform with metal back boxes? Is there a significant reduction in effectiveness / range?

Is it possible to change colors of the light bulb using smartthings
Thiago H. 31 May 2017
Can I use this as a switch for led bulbs in 2 wire installation?
Eli R. 30 May 2017
Can this be wired up to use a 2-way switch the same way as any other dimmer would be?
Keith L. 25 May 2017
Hi. What wireless switch could I use with this dimmer? And do I need a 3rd party device (e.g. Vera or Smartthings) to configure them to talk to each other?
Jez A. 24 May 2017
Hi, will two of these fit in a two gang wall box? I have both pendant and wall lights in my lounge
Michael S. 24 May 2017
Can you confirm that S2 can control a second lighting circuit alongside one on S1?
Simon W. 29 Apr 2017
In the US they sell a touch display that plugs directly into this module but its the wrong size for the UK. Does anyone know if they will sell a UK version?
Gary R. 29 Apr 2017
What does the physical switch attached to this device do? does it activate the dimming or does it just enable/disable the whole device? Forgive the naiivety of the question, I'm still a noob at this
Marc T. 27 Apr 2017
How is this better than the Fibaro Dimmer 2 (which I just bought)? "outperforms all that has come before it" is quite a grand claim - is it just compatible with a broader selection of LED bulbs?
Andrew T. 20 Apr 2017
Can I control 50w of MR16s though a suitable transformer?
