To add a Matter device to SmartThings, put the device in pairing mode. Then open the app, tap Add (+), then Add Device, and scan the device’s Matter QR code. If scanning fails, enter the setup code instead. Choose a hub and room, pick a network if the app asks, and save. The steps below cover what to prepare first, how Thread differs from Wi-Fi, and what to check when pairing fails.
What you need before you start
SmartThings splits Matter setup into two roles, and knowing them explains most requirements. The commissioner adds the device during onboarding, and the phone running the SmartThings app does this job. The controller then controls the device afterward (SmartThings Support).

Phone and app
- Android: SmartThings app version 1.7.91 or higher.
- iOS: iOS 16.2 or higher, with SmartThings app version 1.6.94 or higher.
These are the thresholds in SmartThings’ support article, published January 19, 2023. Newer app versions are the safer choice, so update the app first.

Controller (hub)
SmartThings lists the SmartThings 2018 Hub (IM6001-V3P01) and the Aeotec Smart Home Hub as Samsung Matter-controller examples. The article says these need firmware 45.9 or higher. The SmartThings 2015 Hub handles Matter devices that use Wi-Fi/LAN, but it has no Thread router.

The device itself
Look for the Matter badge and a QR code on the device or its packaging. The QR code contains an 11- or 21-digit setup code, which you can type in if the camera can’t read the QR code. SmartThings says some devices made before Matter may gain support through a firmware update, but that depends on the device. Check with the manufacturer.
Wi-Fi/LAN devices versus Thread devices
Not every Matter device needs Thread. The requirements differ by transport:

- Automate connected devices in your home and set them to turn on or off when doors are opened, people come and go, and much more
- Works with a wide range of smartphone compatible products
| Device type | What it needs |
|---|---|
| Wi-Fi/LAN | A supported Matter controller on your network. The 2015 Hub works for these. |
| Thread | A controller with Thread Border Router capability. A 2015 Hub needs a third-party border router. |
Using a third-party Thread Border Router with a 2015 Hub
- The border router and the hub must be on the same Wi-Fi/LAN.
- During onboarding, select the Thread network when prompted.
- Enter the 32-character Thread Network Key. It may be printed on the border router or shown in the app you used to set it up.
Setting up the border router depends on its manufacturer, so follow its own instructions.
Step-by-step setup
- Put the device in pairing mode, following the manufacturer’s instructions. SmartThings may show a notification when it detects a device in pairing mode, and that notification can start onboarding.
- Open SmartThings and tap Add (+), then Add Device.
- Scan the device’s Matter QR code. If that isn’t possible, choose the option to enter the setup code. The app may also let you pick a brand and device before scanning.
- Select the hub and the room.
- Wait for the connection. If asked, select the Wi-Fi or Thread network.
- Rename the device and save.
Keep the QR code or setup code within reach during pairing. Screens can differ between devices, so the manufacturer’s guide takes priority where it disagrees with the steps above.

If setup fails
Onboarding doesn’t complete
- Confirm you have a compatible Matter controller.
- Make sure the QR code is visible to the camera, or use the setup code.
- Check that the device is in pairing mode and within range of both your phone and the controller.
- Reset the device per the manufacturer’s instructions, then restart the SmartThings app and try again.
No hub or network option appears
Check that the controller is online.
Weak signal or “incompatible network” warning
- For a weak signal, move the network equipment closer.
- For an incompatibility warning, check whether the device supports the Wi-Fi frequency (2.4 GHz or 5 GHz) and the security type your network uses.
- Restarting the device and the controller is also worth trying.
A paired device goes offline
- Check range and obstructions.
- Power-cycle the device and the controller, and restart SmartThings.
- Check the power supply or battery.
- If none of that works, remove the device and add it again.

A Matter device connected to SmartThings can also be shared with another supported service, and it stays connected in SmartThings. Install and set up the other service’s app first. Then:
Rank #4
- Multi-Protocol Smart Hub with Matter Bridge – The M100 is a versatile smart hub compatible with Thread devices and Aqara Zigbee (** Not third-party Zigbee devices), supporting up to 20 Aqara Zigbee devices and 20 Thread devices. As a Matter Bridge, it connects Aqara Zigbee products to other smart home ecosystems, compatible with Apple Home, Amazon Alexa, Home Assistant, etc. Note: Use a 5V⎓0.5A power adapter (not included) and keep the product continuously powered during use.
- Advanced Matter Bridging for Seamless Smart Home Integration – The M100 enables Aqara’s unique features, such as facial recognition and complex automation, to work across Home Assistant and other Matter ecosystems. Expand your smart home with Aqara or third-party Matter devices (requires a Matter-enabled hub). Currently supports lights, thermostats, plugs, switches, buttons, and various sensors (motion, light, door/window, temperature/humidity), with more devices to be added in the future.
- Local Automation for Reliable Performance – Supports local execution of automations for Zigbee and Matter devices, ensuring smooth operation even without Wi-Fi or cloud access. Enjoy millisecond-level response times for a more stable and reliable smart home experience. (Some automation, such as cloud push notification, will still require the cloud connection to be executed.)
- Flexible Power & Small Size – Features a universal USB-A port for power and data, allowing connection to power banks, wall outlets, PCs, or routers for a simple and quick setup. The Hub M100's shaft can be adjusted within a 210-degree range, making its placement extremely flexible.
- 2.4GHz Wi-Fi 6 for Faster & Security—This product supports a 2.4GHz Wi-Fi 6 wireless network connection, which enables more efficient connections with advanced WPA3 security. Wi-Fi 6 ensures smoother performance even in high-traffic environments, allowing multiple devices to connect without compromising speed or reliability. Note: To ensure a stable connection, place the Hub M100 between 6 to 19 feet from the router.
- Open the device in SmartThings and go to the More menu.
- Choose Share with other services, then Share device.
- Scan the QR code the app generates, or enter its setup code, in the other service.
This generated code is separate from the QR code printed on the device. A Matter device can connect to five services. If it is already at that limit, remove one service before sharing again.
