ThirdReality and Matter: native Wi-Fi/Thread devices and the MZ1 Zigbee bridge

By Rowan Hale, editor (pen name) · Reviewed 2026-10-28

ThirdReality has native Matter over Wi-Fi and Thread devices—Smart Plug M3, Smart Water Leak Kit KM1, Smart Switch MT1, Smart Night Light-T, and Smart Garage Door Opener—and the Smart Bridge MZ1 for older Zigbee devices. This guide covers each product's requirements, the MZ1 multi-admin setup steps for Apple Home, Google Home, Amazon Alexa, and SmartThings, and the MatterCheck per-type support answers for leaks, plugs, garage door openers, and switches.

Facts on this page come from the CSA Distributed Compliance Ledger, ThirdReality product pages, the MZ1 quick start guide dated 1 April 2026 (v1.00.95), and microcontrollerslab.com's Matter bridge comparison, plus MatterCheck platform data. Product listings, firmware and compatibility claims can change. Check the maker page or the CSA ledger before buying.

Matter over Wi-Fi devices: Smart Plug M3, Smart Water Leak Kit KM1, and Smart Garage Door Opener

All three ThirdReality Wi-Fi Matter products need a 2.4 GHz Wi-Fi network and a compatible Matter controller. None uses a Zigbee hub or a ThirdReality bridge.

Smart Plug M3

The Smart Plug M3 is a Matter over Wi-Fi 15 A smart outlet. ThirdReality's product page says it works with SmartThings, Apple Home, Amazon Alexa, Google Home, Home Assistant and Homey, and that no proprietary hub or bridge is required. The listing specifies that the M3 has no power meter and is 2.4 GHz Wi-Fi only. ThirdReality also states the plug carries ETL certification and a one-year warranty. ThirdReality's Smart Plug M3 page

On the same page, ThirdReality notes that the power-on state after a power loss can be customised to on, off, toggle, or previous state, and that this function is supported in the 3R-Installer app and Home Assistant. The maker states that local control without internet is supported only by Home Assistant and Apple Home. Over-the-air updates run through the 3R-Installer app without an additional hub.

Smart Water Leak Kit KM1

The Smart Water Leak Kit KM1 is a Matter over Wi-Fi kit with one KM1 controller and three water detectors. The product title on ThirdReality's page says it works with Apple Home, Alexa, Home Assistant, and Homey, and that the detectors have a three-year battery life. The listing describes a loud 100 dB alarm on the controller and a signal range of up to 328 ft (100 m) in open areas. The page confirms the kit needs 2.4 GHz Wi-Fi and a Matter controller, with no Zigbee hub. ThirdReality's KM1 leak sensor page

Smart Garage Door Opener

The Smart Garage Door Opener is a Matter over Wi-Fi garage door controller with a pre-matched tilt sensor. ThirdReality says the main unit and tilt sensor arrive pre-paired, and the opener connects to power through a USB-C cable. The product page states compatibility with Alexa, Apple Home, Google Home, SmartThings, Home Assistant, and Homey, and adds that 2.4 GHz Wi-Fi and a Matter controller are required. The listing also describes open/close status monitoring and temporary access for family members or couriers. ThirdReality's garage door opener page

Matter over Thread devices: Smart Switch MT1 and Smart Night Light-T

These two ThirdReality devices use Thread instead of Wi-Fi. Both require a Matter controller and a Thread border router, and neither needs a Zigbee hub.

Smart Switch MT1

The Smart Switch MT1 is a Matter over Thread snap-on switch that mechanically presses an existing toggle or rocker switch. The product page says it needs no wiring, fits multi-gang setups, and works with 12 V, 24 V, 110 V, and 220 V switches. It is powered by two AAA batteries, which ThirdReality rates for about one year of typical use. ThirdReality's Smart Switch MT1 page

ThirdReality's page lists compatibility with Apple Home, Google Home, SmartThings, Homey, and Home Assistant, and the compatibility note also mentions Alexa. The maker names these Matter controllers as compatible: Apple HomePod mini, Apple HomePod, Apple TV, Google Nest Hub (2nd Gen), Nest Hub Max, SmartThings (2018), SmartThings Station, Aeotec Hub, Homey Pro, Home Assistant with a Thread border router, and the Third Reality Smart Bridge, which only supports linking from Matter platforms. The product page requires a Matter controller plus a Thread border router for setup.

Smart Night Light-T

The Smart Night Light-T is a Matter over Thread colour night light with a motion sensor and an illuminance sensor. ThirdReality's page says the light supports RGB colours and adjustable brightness from 1% to 100%. It lists compatibility with Apple Home, Google Home, Home Assistant, and Homey, and states that a Thread border router is required and not included. The maker says OTA updates run through the 3R-Installer app. ThirdReality also describes using the night light in automations with the garage door opener, such as changing light effects based on the door's open or closed state. ThirdReality's Night Light-T page

The CSA Distributed Compliance Ledger also lists other ThirdReality products, including the Smart Color Bulb ML1, Smart Plug PM1, and Smart Color Night Light. MatterCheck does not state the transport or protocol for those three products. A ledger listing is not by itself proof of certification; see how to check Matter certification.

Smart Bridge MZ1: ThirdReality Zigbee devices to Matter

The Smart Bridge MZ1 links ThirdReality Zigbee end devices to Matter so they can appear in Matter platforms. ThirdReality's bridge page lists the MZ1 at $29.99 and describes it as a Zigbee-to-Matter bridge with a USB-C power interface, 2.4 GHz Wi-Fi, and OTA support through the 3R-Installer app. The page also says the bridge is compatible with Google Home, Apple Home, SmartThings, Home Assistant, and other Matter platforms. ThirdReality's Smart Bridge MZ1 page

The MZ1 quick start guide gives the LED behaviour and reset method. When the bridge is powered on, the power LED is on. A fast-blinking Wi-Fi LED means the bridge is ready for Wi-Fi setup, a solid Wi-Fi LED means Wi-Fi is connected, and a slow-blinking Wi-Fi LED means the connection was lost or is resuming. The Zigbee LED is on when Zigbee is idle and blinks slowly when the bridge is ready for Zigbee pairing. A fast-blinking power LED indicates a self-test fault, and all three LEDs fast-blinking means the bridge is factory resetting. To factory reset, long-press the reset button through the pinhole until all three LEDs fast blink. the MZ1 quick start guide

The recommended setup path is to install the 3R-Installer app first, power on the bridge, tap + in the app, scan the Matter QR code, and configure the 2.4 GHz Wi-Fi network. After network configuration, open the bridge page in the app and tap Check Updates for firmware updates. Then tap Bridge Zigbee Devices, put ThirdReality Zigbee devices into pairing mode, and pair them to the bridge. Finally, tap Link With Matter Enabled Services to copy the manual setup code or scan the QR code within 3 minutes and add the bridge to other Matter ecosystems through multi-admin. the MZ1 quick start guide

microcontrollerslab.com's Matter bridge comparison lists the MZ1 under "THIRDREALITY only" for accepted Zigbee brands and places it in the "Cheapest Single-Brand" slot. The comparison warns that Matter bridges only expose features that map to a Matter device type, so a Zigbee button may arrive as a generic switch and vendor-specific extras often stay in the brand app. microcontrollerslab.com's Matter bridge comparison

MZ1 pairing paths in Apple Home, Google Home, Amazon Alexa, and SmartThings

The MZ1 quick start guide gives app-specific steps for the four platforms below. The same core sequence applies: set up the bridge in 3R-Installer first, copy the setup code, and add the bridge to the platform through multi-admin. The setup code is valid for 3 minutes. the MZ1 quick start guide

Apple Home

The manual lists iOS 16.6 or later as the required iPhone software and names HomePod, HomePod mini, or Apple TV as Matter-supported controllers. Set up the bridge in 3R-Installer and copy the setup code. In the Home app, tap +, tap Add or Scan Accessory, then tap More Options and select Smart Bridge MZ1. Paste the setup code, set the location and name, and the bridge is added to My Home. Zigbee devices already paired to the bridge in 3R-Installer should appear automatically. the MZ1 quick start guide

To add more ThirdReality Zigbee devices later, press the reset pinhole with a pin to enable Zigbee pairing; the Zigbee indicator turns blue and blinks. Then put the Zigbee devices into pairing mode. To share the bridge to another Matter ecosystem, long-press an attached accessory, tap Accessory Settings, tap Bridge, then tap Turn On Pairing Mode to generate a new setup code. See Matter on Apple Home.

Google Home

The manual lists the Google Home app version requirements as Android 3.3.1.4 or later and iOS 3.3.104 or later. Set up the bridge in 3R-Installer and copy the setup code. In the Google Home app, tap +, tap New device, choose a home, tap Next, choose the Matter bridge, tap Next, then Continue without scanning, paste the setup code, and create a name for the bridge. Pre-connected devices attached to the bridge should update automatically. the MZ1 quick start guide

To add more Zigbee devices later, press the reset pinhole to enable Zigbee pairing, then put the Zigbee devices into pairing mode. See Matter on Google Home.

Amazon Alexa

The MZ1 manual lists Alexa app version requirements as Android build 2.2.521848.0 or later and app version 2023.15 or later, or iOS build 2.2.548660 or later and app version 2023.15 or later. Set up the bridge in 3R-Installer and copy the setup code. In the Alexa app, tap + in the upper right on the device page, tap Add Device, scroll to Other, choose Matter, then tap Try Numeric Code Instead to enter the code. the MZ1 quick start guide

To generate a setup code from Alexa, open the Device Settings page, tap Other assistants and apps, then Add another, and copy the setup code. See Matter on Alexa.

SmartThings

The manual lists SmartThings app version 1.8.01.22 or higher for Android and iOS SmartThings app version 1.7.02.16. It names SmartThings Hub V2 and V3 and Aeotec Smart Home Hub as Matter-supported controllers. In the SmartThings app, tap +, tap Add device, choose Matter, scan the QR code on the bridge, and select a hub to connect the device. the MZ1 quick start guide

To add Zigbee devices after setup, press the reset pinhole to enable Zigbee pairing, then put the ThirdReality Zigbee devices into pairing mode. To share the bridge, open Device Settings, tap Share with other services, then Share device, and use the QR code or numeric code in the next ecosystem. See Matter on SmartThings.

Home Assistant and Homey

ThirdReality product pages list Home Assistant and Homey compatibility for the Smart Plug M3, Smart Water Leak Kit KM1, Smart Switch MT1, Smart Garage Door Opener, and Smart Night Light-T. Home Assistant requires the Matter Server add-on, with Home Assistant OS recommended. Homey requires a Homey Pro, Homey Pro mini, or Homey Self-Hosted Server as a Matter controller. The MZ1 manual does not give separate app-specific steps for Home Assistant or Homey, so follow the 3R-Installer setup first and then add the bridge through each platform's Matter device flow. See Matter on Home Assistant and Matter hubs and Thread border routers.

Matter device-type support for leak sensors, plugs, garage door openers, and switches

MatterCheck's per-type answers cover the device types relevant to ThirdReality's native Matter products. These records are per device type and platform, not tests of specific ThirdReality products.

MZ1 and native-device pairing failures

If a ThirdReality Matter device or the MZ1 bridge will not pair, check that the device is in pairing mode, the setup code is still valid, and the platform hub is on the same 2.4 GHz Wi-Fi network or has a working Thread border router. For the MZ1, the setup code from 3R-Installer expires after 3 minutes. For step-by-step troubleshooting, see Matter device not pairing.
