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.

Setup Instructions Overview

This is the digital manual for the Blue Series Smart 2-1 Switch (On/Off or Dimmer).

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 & Pairing

This section assumes you have your switch wired correctly, the blue LED bar is lit up and you are ready to pair your switch. If you have not wired it and tested to see if it works locally, please visit the Wiring Instructions section first.


When you are ready to pair your switch, please start the pairing process on your Zigbee enabled hub.

Once your hub has started the pairing process, check to make sure the LED Bar (D) on your switch is pulsing blue (it should automatically start pulsing when power is restored to it). If it's not pulsing blue, quickly tap three (3) times on the configuration/favorites button (C).

If your switch pairs successfully, the LED Bar (D) will blink Green temporarily and then go back to blue as shown in the video below. If the switch does not pair successfully, the LED Bar (D) will blink red temporarily and then go back to blue. If you run into issues where your switch is not pairing, you may have to reset the switch.

Video Demonstration

NOTE: Your switch will start to pulse blue as soon as you restore power to it. If it isn't pulsing, please follow the video underneath this one.

If you switch isn't pulsing blue, then please follow this video to start the pairing process

Factory Resetting

To reset your switch, hold down on the top of the paddle (on) and the config/favorites button simultaneously for 20 seconds until the LED Bar (D) turns red. It will blink red three times to confirm the switch has been reset as shown in the video below.

Video Demonstration

NOTE: Video sped up to save time/space

Getting to Know Your Switch

Please refer to the above diagram to get to know your switch.

A. Light On / Increase Dim % Level: Tap 1x to turn on your light or hold to increase the brightness level (dim percentage). In addition, it can be used to activate scene control (multi-taps and holds) where up to 7 scenes can be added*.

B. Light Off / Decrease Dim % Level: Tap 1x to turn off your light or hold to decrease the brightness level (dim percentage). In addition, it can be used to activate scene control (multi-taps and holds) where up to 7 scenes can be added*.

C. Config / Favorites Button: Used to configure certain parameters of the switch. In addition, it can be used to activate scene control (multi-taps and holds) where up to 7 scenes can be added*.

D. RGB LED Bar: Multi-functional LED bar that shows the % level at which your switch is at. In addition, it can be used as a notifier* for various events (ie: turn red when alarm is armed, pulse purple if garage is left open, etc).

E. Air Gap: This can be pulled out to cut power to the load and is there for safety purposes.

* Hub must support these features.

Quick Tap Sequences

These sequences can be used to program your smart switch. However, we recommend that if you have a hub that supports parameter changes (ie: SmartThings, Hubitat, Home Assistant, etc) you use the hub to make these changes as it's much easier than doing it manually at the switch. Please follow the link below to see all the Quick Tap Sequences along with videos.

LED Bar Indicators

This switch uses its LED bar to display when certain events take place and/or during configuration modes. Please see the link below to better understand what the various LED color/animations mean.

Recommended Installation Practices: Use only indoors or in an outdoor rated box. Turn off the circuit breaker. Installing this switch and module with the power on will expose you to dangerous voltages. Connect only copper or copper-clad wire to the switch or module.

To reduce the risk of overheating and possible damage to other equipment, do not install to control a receptacle, a motor-operated appliance, a fluorescent lighting fixture or a transformer supplied appliance and do not use the VZM31-SN load output to control no more than indicated, which is: 600 Watts (Incandescent), 300 Watts (LED), and 150 Watts (CFL).

Dimming an inductive load (by connecting to the light load wire), such as a fan or transformer, appliance, motor or any device not specifically designed for dimming, could cause damage to the dimmer, the load bearing device, or both. To install your 2-1 Switch (VZM31-SN), you’ll need to identify the following four wires (NOTE: Neutral is not mandatory, but recommended):

  • Line: Usually black and can also be called the, “hot” or “live” and carries 120VAC electricity into the electrical box

  • Neutral*: Usually white and is commonly daisy chained from box to box, usually appearing as a white wire bundle.

  • Load: Usually black, blue or red

  • Ground: Bare copper wire or metal fixture (if grounded)

* Neutral is mandatory in certain installations. See the compatibility chart in Step 4.

If you are having difficulties identifying wires, please consult an electrician.

Pratiques d’installation recommandées: Utiliser uniquement à l’intérieur ou à l’extérieur dans une boîte adaptée aux conditions extérieures. Éteignez le disjoncteur. L’installation de cet interrupteur et de ce module alors que le courant est allumé vous exposera à des tensions dangereuses. Connectez uniquement un fil de cuivre ou gainé de cuivre au commutateur ou au module.

Pour réduire le risque de surchauffe et d’endommager d’autres équipements, il est important de connecter des lumières incandescentes ayant moins de 600 watts, des lumières DEL ayant moins de 300 watts, des ampoules fluocompactes ayant moins de 150 watts ou un ventilateur utilisant moins de 1 ampère et ce dernier avec l’interrupteur en mode marche/arrêt uniquement.

La gradation d’une charge inductive, comme un ventilateur ou un transformateur, pourrait endommager le gradateur, l’interrupteur ou les deux appareils. Veuillez régler l’interrupteur en mode marche/arrêt si vous utilisez un ventilateur.

Pour installer votre interrupteur 2 en 1 (VZM31-SN), vous devrez identifier les quatre fils suivants (REMARQUE: le neutre est optionnel, mais recommandé) :

  • Ligne: généralement noire et peut également être appelée « chaud » ou « sous tension » et transporte l’électricité 120 VCA dans le boîtier électrique

  • Neutre: habituellement blanc et connecté en série d’une boîte à l’autre, les fils sont habituellement attachés ensemble dans la boîte électrique

  • Charge: habituellement noire, bleue ou rouge

  • Mise à terre: fil de cuivre nu ou boîtier métallique (si celui-ci est mis à la terre)Si vous rencontrez des difficultés à identifier les fils, veuillez consulter un électricien.

Équipement médical: Veuillez ne pas utiliser cet interrupteur pour contrôler de l’équipement médical ou nécessaire à la survie. Les appareils Zigbee ne doivent jamais être utilisés pour contrôler la marche or l’arrêt d’équipement médical et/ou nécessaires à la survie.


Before we go into actual steps, it’s important to be familiar with the vernacular used on the following pages. Please see below:

  • Line: This is your hot wire (120V) - aka: “live” wire

  • Load: This is the wire that runs from your light switch to what you’re controlling (ie: bulb(s), fan, etc)

  • Neutral: This is the wire that carries current back to the power source (you may not have this in your house)

  • Single-Pole: One switch controlling one or more load(s)

  • Multi-Way: Refers to 3-Way (2 switches, 1 load), 4-Way (3 switches, 1 load), or 5-Way setups (4 switches, 1 load)

  • Toggle (“Dumb”) Switch: Refers to your existing switch (ie: the switch(es) you had before replacing with your smart switch(es))

  • Aux Switch: Refers to the Inovelli Aux Switch (

Pre-Wiring Steps

Please use the below steps to determine if your wiring is compatible and to understand what schematic you should choose.

Step 1 - Determine Wiring Type

The first step is to determine how many switches control your load(s) (aka: light(s)).

Using the diagram below, please determine what your wiring type is and remember this selection :

  • Single-Pole: One switch controls one load (load may contain more than one light, etc).

  • Multi-Way: Two or more switches control one load (load may contain more than one light, etc). We will use the term, “multi-way” instead of 3-Way, 4-Way, 5-Way, etc as the programming of the switch is the same regardless.

Wiring Type (Circle One): Single Pole or Multi-Way

Step 2 - Determine Switch Layout

If you determined in Step #1 that your switch is single-pole, you can skip this step. This step is for multi-way setups only.

Using the diagram below, please determine what your wiring layout is and remember this selection :

  • Smart Switch + Toggle Switch: One smart switch and one (or more) toggle/existing switch (one already in your wall).

  • Smart Switch + Aux Switch: One smart switch and one (or more) aux/add-on switch (Model #: AUX01 or

  • Smart Switch + Smart Switch: Two (or more) smart switches.

Switch Layout (Circle One): Toggle, Aux, or Smart Switch(es)

Step 3 - AC Power Type

In this step, we will determine if you have a neutral wire, which is typically white and located in the back in your switch gang-box (typically in a bundle of wires tied together). Here are some signs you may have a neutral wire:

  • If your house was built in the mid-1980’s or later

  • If there is an outlet (receptacle) near the switch

  • If switches are in the same gang-box (regardless of the year your house was built)

See below for details on checking for a neutral wire.

AC Power Type (Circle One): Neutral or No Neutral

Step 4 - Compatibility Check

In this step, we will determine if your switch can be installed with your current wiring setup. If not, you can see some alternate solutions on how to accomplish compatibility.

Taking the answers you circled in Steps 1-3, please see the chart below to see if your switch is compatible with your setup.​

Example: If you circled, “Multi-Way”, “Toggle Switch” and “Neutral”, you will see that your wiring is compatible. However, if you circled, “Multi-Way”, “Toggle Switch” and “No Neutral”, you will see that your wiring is not compatible and you will need to purchase an auxiliary switch (

For installations where no neutral wire is present, you may need to install a special bypass to prevent flickering and/or keep your switch powered. Bypasses can be purchased here:

Step 5 - Switch Installation

The last step is to physically install your switch. After you’ve determined your wiring type, switch layout, AC Power type and whether or not you have a compatible setup, it’s time to look at the wiring schematics and install your switch. Please move on to the section below that goes over the various wiring schematics and remember the choices from Steps 1-3 above when you're searching the schematics.

Wiring Schematics

Please see the following link to the wiring schematics for this switch: Blue Series 2-1 Switch Schematics

UL specifies the tightening torque for the screws to be 0.8 N.m (7.08 lbf-in).

Manual Setup

PLEASE NOTE: We recommend you use your smart hub to change any parameters. However, if you are an electrician or do not have a smart hub and your switch is not working properly, you can follow the instructions below to manually program the switch.

If you plan on using your switch on an on/off switch and in a single-pole setting, you may skip this step. If you plan on using your switch as a dimmer switch and/or in a multi-way setup, please continue.

Since this switch has so many different available configurations (on/off, dimmer, smart, aux, toggle, neutral, non-neutral, etc), you may need to manually the switch to work manually by following the directions below..

Switch Configuration (Single-Pole or Multi-Way)

Use the button sequence below to adjust the mode of the switch according to your wiring configuration. The LED bar (D) will flash the associated color to indicate success.

Hub/Gateway Setup

The Inovelli smart switch can be used on various hub platforms such as: SmartThings, Home Assistant - ZHA, Home Assistant - Zigbee2MQTT, Hubitat, and Amazon Echo. If you'd like specific instructions on how to setup this switch on your hub's platform, please click the links below to be taken to them:

If you don't see your hub listed above, please go to the, "Quick Setup & Inclusion" section for generic instructions.

Advanced Features

The advanced features shown below are what is built into the switch firmware, and may or may not be supported by your hub/ gateway. We’ve confirmed they’re supported on SmartThings, Hubitat, and Home Assistant (ZHA and Zigbee2MQTT).

These switches are packed with a ton of amazing features, which include scene control (multi-tap), animated notifications, smart bulb mode, energy monitoring, and approximately 60 different parameters to customize your switch.

Switch Parameters

To see the list of parameters on this switch, please click on the following link: Blue Series 2-1 Switch Parameters

All parameters can be changed via your hub if your hub supports parameter changes (most do). If your hub does not support parameter changes, or you do not have access to your hub, you can change some parameters directly from the switch. These instructions can be found on our GitHub page as well.

Animated Notifications

Animated Notifications can be setup to notify you of certain events. Some common examples are:

  • Switch LED Bar pulses orange if the garage door is left open past 10pm

  • Switch LED Bar turns red if the alarm system is armed

  • Switch LED Bar chases green at 10am to remind you to take your medicine

To see examples of the various notifications, check out our Toolbox located here and select the On/Off + Dimmer Switch (VZM31-SN) under, "Zigbee" and click the dropdown where it says, "Effect":

Or you can check out our article: Animated Notification Examples

Setup instructions are different for each hub, so we've created instructions for the following hubs:

Scene Control

Scene control allows you to multi-tap your switch to activate certain scenes. Some common examples are:

  • Double-Tap up to activate a movie scene where multiple smart lights turn on to a certain dim level and color

  • Double-Tap down to activate a bedtime scene where all your lights turn off, doors lock, and temperature gets set to 68

  • Triple-Tap the configuration/favorites button to lock all your doors and shut the garage door

Setup instructions are different for each hub, so we've created instructions for the following hubs:

Smart Bulb Mode

Smart Bulb Mode is used to maintain power to your smart bulbs if you have them wired to your smart switch. Said differently, smart bulbs require constant power to them and with traditional light switches (non-smart), if you turn the light switch off, power is cut to the smart bulb and they are unable to communicate with the hub and fall offline. By using Smart Bulb Mode, you will maintain constant power to the smart bulb and use virtual commands from the switch to turn on/off/dim your smart bulb.

Setup instructions are different for each hub, so we've created instructions for the following hubs:

Zigbee Binding

Zigbee Bindings are used to "bind" two or more Zigbee devices together. The benefit is that when two Zigbee devices are bound together, they no longer need the hub to communicate with each other (they will still report status to the hub). This is important because if your hub goes offline, the bound Zigbee devices will still communicate. Some common examples are:

  • 2+ Zigbee switches bound together to create a virtual multi-way setup (like if you have a light switch at the top of your basement stairs and another one at the bottom but they are on different circuits, you can now associate them together so that when one turns on, so does the other)

  • Zigbee switch to Zigbee bulb

Setup instructions are different for each hub, so we've created instructions for the following hubs:

Project New Horizon

This project was Inovelli’s first venture into the Zigbee protocol as we’re traditionally known for our work in Z-Wave. Hence the name, “New Horizon”.

To reach this, “New Horizon”, we relied heavily on our amazing community who quickly grasped onto this project and helped us along the way. In fact, many of the signatures you see in the box and this manual are community members, who’ve stepped up and helped develop this product with us. We believe the products should be built by people who actually use them not by some corporate project manager.
