DISCLAIMER: You may notice there are a lot of over-used keywords or phrases as well as English that seems a little off. This is because these articles are used to feed our AI Robot (Ira) and she needs the data to be structured in a certain way.

REMINDER: This switch is only to be used to control lights (except ballasts or any lights connected to a transformer). Do not use the switches on outlets, fans, or any other inductive load.

NOTICE: If you're having trouble pairing, please ensure the following:

  • Matter Devices and Controllers Must Be on the Same L2 Network

  • VLAN Use Requires Matter Controller/Server to operate on that VLAN

  • Make sure your Google Home app and your Google/Nest Border Router firmware is up-to-date

  • IPv6 Networking is Required for Matter Networks. Link-Local Addresses Are Allowed, Look for a Setting in your Router Called “Enable IPv6.” (Note: This does not require you to configure the IPv6 connection for your entire network)

This is the digital setup instructions for the White Series Smart Dimmer Switch (formerly the 2-1 Switch) on the Google Home platform.

NOTE: Default LED Bar color is blue.


Navigating the Instructions

Please click on any of the sections in the Table of Contents to get started. We recommend working your way down as it follows an intentional flow that is user friendly and hub/gateway specific. As always, any questions, please see the Additional Resources links section or submit a ticket, we’re happy to help.


Quick Setup Instructions

Follow these if you have already installed the Dimmer switch before and are just looking for some quick pairing instructions. If this is your first time installing the Dimmer switch, please skip this section and work your way through the various sections below starting with the Prerequisites.

This section assumes the following:

  1. You’ve wired the switch and it works manually

Let’s begin:

  1. Open up your Google Home App and click on, "Devices" at the bottom

  2. Next, click on, "+ Add"

  3. Click on, "Matter-enabled device"

  4. Scan the QR Code on your switch (located at the bottom left) or the QR Code on the back of your package

  5. Google will then ask you if you want to connect this device to your Google Account - click, "Agree"

  6. Google should then search for and add your device (NOTE: If your LED Bar is not automatically pulsing as shown in Video #1, please tap the favorites button 3x as shown in Video #2) - if successful, the LED Bar will flash green and if unsuccessful, the LED Bar will flash red. If it flashes red, please see Video #3 below to factory reset your device and start this process over

  7. Click, "Done" once complete

NOTICE: If you're having trouble pairing, please ensure the following:

  • Matter Devices and Controllers Must Be on the Same L2 Network

  • VLAN Use Requires Matter Controller/Server to operate on that VLAN

  • Make sure your Google Home app and your Google/Nest Border Router firmware is up-to-date

  • IPv6 Networking is Required for Matter Networks. Link-Local Addresses Are Allowed, Look for a Setting in your Router Called “Enable IPv6.” (Note: This does not require you to configure the IPv6 connection for your entire network)

Please note that there will be 6 different devices that show up in Google Home (shown in the red box below). This is unfortunately a limitation on Google Home's platform in that it shows all the major configuration options as devices.

The device shown in the blue box is the light switch, whereas the device shown in the green box is the switch LED Bar color used for notifications. These are the only two devices you will need.

Video #1 & Video #2

Video #2: Pressing the favorites button 3x


Video #3: Factory resetting your switch

If your LED bar refuses to pulse blue or you are having issues pairing, then please hold down on the top of the paddle as well as the config/favorites button for approximately 20 seconds until the LED Bar turns Red and then let go as shown in, "Video #2" in the drop down above. The LED Bar will blink red three times to confirm as shown in the video below.

IMPORTANT: The Google Home app has no way of changing the switch from a simulated On/Off Switch to a Dimmer Switch so you will have to do it manually at the switch.


Google Home Limitations

Google Home is a fantastic hub that offers a ton of features along with voice control and is backed by an amazing company.

With that said, there are some limitations with the hub that you should be made aware of.

  1. There is no way to access the advanced features on your switch from the Google Home app (ie: parameters, animated notifications, scene control, etc) and you will only be able to change select parameters locally at the switch

  2. You will have to manually change the switch from a simulated On/Off Switch to a Dimmer Switch and vice versa

  3. You will still be able to control the LED Bar when the switch is in On/Off mode (other platforms, the LED Bar only shows on/off like it should)


Installation Instructions

Before setting up your switch within the Google Home app, you will have to manually install your switch in the wall and have it powered up. In order to do that, you (or your licensed electrician) will need to follow our Wiring Instructions which can be found below:


Pairing Instructions

Please follow the instructions below to include/pair your White Series Dimmer Switch

  1. Open your Google Home App and click on the, "Devices" tab at the bottom

  2. Click on the, "+ Add" button

  3. Click on, "Matter-enabled device"

  4. Click, "Agree" when Google asks if you want to connect the device to your Google account


  5. Scan the QR Code at the bottom-left of your switch (or on the back of the device box)

  6. Once Google starts the pairing process, your switch should automatically start the pairing process and the LED Bar should start to pulse blue as shown in Video #1. If the LED Bar doesn't automatically start to pulse blue tap on the favorites button three times as shown in Video #2 below.

    Video #1: Switch Pulsing Blue after QR Code is scanned

    Video #2: Pressing the favorites button 3x

  7. Google will then connect to the device, generate Matter credentials, check your network connectivity, and connect your device to Google Home. Once your device is connected, click on, "Done"

    NOTICE: If you're having trouble pairing, please ensure the following:

    • Matter Devices and Controllers Must Be on the Same L2 Network

    • VLAN Use Requires Matter Controller/Server to operate on that VLAN

    • Make sure your Google Home app and your Google/Nest Border Router firmware is up-to-date

    • IPv6 Networking is Required for Matter Networks. Link-Local Addresses Are Allowed, Look for a Setting in your Router Called “Enable IPv6.” (Note: This does not require you to configure the IPv6 connection for your entire network)

  8. Back on your, "Devices" page, you will see 6 different devices (as shown below in the red rectangle). Unfortunately, there is a quirk with Google in that it shows all the device's endpoints and 4 of the 6 devices are useless. In the below example, the device labeled, "Inovelli Dimmer Switch" is not usable, whereas the device circled in blue is your actual switch, and the device circled in green is an endpoint that is used to set color notifications.

  9. Once your switch is successfully paired, check to make sure you have basic functionality of your switch by turning it on/off (if you are going to be using it as a dimmer, please move to the, "Switch Configuration" section below).

NOTE: By default the switch is setup as a simulated On/Off switch so it will only turn On/Off (this means you will not be able to dim). This is for safety reasons. If you'd like to change your switch to be a Dimmer, then please move to the Switch Configuration section below.


Switch Configuration

In this section, we will help you change your switch mode (ie: Simulated On/Off or Dimmer) and type (Single-Pole or 3-Way Aux). As noted above, because the Google Home app is limited in what it can do, we will have to change these settings manually at the switch itself.

If you are trying to setup your switch in Smart Bulb Mode, please still select the Switch Mode and Type from the below instructions, and then follow the directions to setup Smart Bulb Mode

Switch Mode - On/Off

By default, your White Series Dimmer Switch is set to be an On/Off switch and will only turn On/Off (ie: there is no dimming). If this is how you intend to use the switch, you can skip this step. We're just going to show you how to change it to a Dimmer for reference.

To put your White Series Dimmer Switch in On/Off Mode, hold down on the top part of the paddle (on) while simultaneously tapping the configuration button three (3) times (do not let go of the paddle when finished tapping the config button). Wait for the LED Bar to flash solid red (and then let go of the paddle) indicating the switch has changed to an On/Off switch.

Video Demonstration

Switch Mode - Dimmer

By default, your White Series Dimmer Switch is set to be an On/Off switch and will only turn On/Off (ie: there is no dimming). If you'd like to change your switch to a Dimmer switch, then please follow the directions below.

To put your White Series Dimmer Switch in Dimmer Mode, hold down on the bottom part of the paddle (off) while simultaneously tapping the configuration button three (3) times (do not let go of the paddle when finished tapping the config button). Wait for the LED Bar to flash solid orange (and then let go of the paddle) indicating the switch has changed to a Dimmer switch.

Video Demonstration

Switch Type - Single-Pole

By default, your White Series Dimmer Switch is set to be installed in a Single-Pole setup (ie: one switch controls one load). If this is how you intend to use the switch, you can skip this step. We're just going to show you how to change it to a multi-way (2+ switches controlling a load) with an aux switch for reference.

To have your White Series Dimmer Switch work as a Single-Pole switch, hold down on the bottom part of the paddle (off) while simultaneously tapping the configuration button five (5) times (do not let go of the paddle when finished tapping the config button). Wait for the LED Bar to flash solid violet (and then let go of the paddle) indicating the switch has enabled Single-Pole Mode.

Switch Type - Multi-Way (Dumb)

By default, your White Series Dimmer Switch is set to be installed in a Single-Pole setup (ie: one switch controls one load). If you'd like to change your switch to work in a multi-way setup with a dumb/existing switch, then please follow the directions below.

To have your White Series Dimmer Switch work with your existing, "dumb" switch in a multi-way (3-Way) setting, hold down on the bottom part of the paddle (off) while simultaneously tapping the configuration button five (5) times (do not let go of the paddle when finished tapping the config button). Wait for the LED Bar to flash solid pink (and then let go of the paddle) indicating the switch has enabled 3-Way + Dumb Switch Mode.

Video Demonstration

Switch Type - Multi-Way (Aux)

By default, your White Series Dimmer Switch is set to be installed in a Single-Pole setup (ie: one switch controls one load). If you'd like to change your switch to work in a multi-way setup with an auxiliary switch, then please follow the directions below.

To have your White Series Dimmer Switch work with an Auxiliary (Add-On) switch in a multi-way (3-Way) setting, hold down on the top part of the paddle (on) while simultaneously tapping the configuration button five (5) times (do not let go of the paddle when finished tapping the config button). Wait for the LED Bar to flash solid white (and then let go of the paddle) indicating the switch has enabled 3-Way + Aux Switch Mode.

Advanced Features

This switch is packed with features and most of them come directly from this community. They've been debated back and forth, added to wishlists, and talked about over the course of 4+ years.

While the advanced features are built into the light switch firmware, they unfortunately are not recognized by the Google platform at this time. The only advanced feature Google supports is, "Smart Bulb Mode" which is discussed more below.

Smart Bulb Mode

Smart Bulb Mode is a special mode that allows you to use your Inovelli smart switch to control smart bulbs. Rather than cutting power to your smart bulbs, Smart Bulb Mode tells the switch to send a digital signal to your bulbs or your hub to turn on/off or dim.

For directions on how to control smart bulb(s) from your White Series Dimmer Switch, please follow the directions in the, "Controlling Smart Bulb(s) from a Smart Switch • Google Home" article.

Color Notifications

Color notifications are used when you want to have a visual cue on your LED bar notify you of a certain event. A few examples would be:

  • LED Bar turns purple if your garage door is left open

  • LED Bar turns red if your front door is unlocked

  • LED Bar turns orange if a door is opened at night time

These notifications are accomplished by using, "Automations" within the Google Home App.

For more information about Animated Notifications as well as some examples of how to set them up, please visit the following article: Setting Up Color Notifications • Google Home
