Set Up Your Smart Device via Matter

This is a Matter-certified device. You can integrate it into any Matter ecosystem you prefer for easy control, such as Alexa, Google, and Apple ecosystems. As IoT manufacturers are working to optimize the user experience of Matter setup, the setup process and user experience should improve over time. Follow the instructions below to set up your smart device via the Matter app.

Before You Start

• Get a Matter Controller: This is needed to connect and manage Matter devices on your home network. For instance, Apple TV and HomePod are examples of Matter controllers. For details, please refer to the Part 3. General Questions for TP-Link Matter-enabled Devices at https://www.to-link.com/support/faq/3520/.

- Reset Your Device: It's important to start with a fresh device. Here's how:

- For most devices: Press and hold the 'Reset' button for 10 seconds.

- For smart bulbs: Turn the light switch off and on five times, with a 2-second pause between each action.

- Connect to Wi-Fi: Connect your phone to the same Wi-Fi network as your Matter controller. Choose the 2.4 GHz network if 2.4 GHz and 5 GHz networks are separate.

- Access Matter Setup Mode: This mode turns off in 15 minutes after the device is powered up. To return to setup, simply turn your device off and then back on.

- Locate Matter Setup Code: Look for a QR code or a numeric code on your device or in its packaging. Snap a picture of it for future reference.

- Regarding the Matter Code: The original Matter code can only be used for setup in one app (you can reuse it after a device reset). If you wish to set it up in multiple apps, generate a new code using the first app for all subsequent ones.

How to Set Up

*Setup processes may vary between different apps.

1. Turn on Bluetooth on your phone.
2. Open the smart home app, and either scan the Matter QR code or input the given numeric code.
3. Connect your device to the same network as your controller.
4. Follow the instructions in the app to complete setup.

Failed to Set Up?

Refer to the following and you can resolve most setup issues.

1. Update Firmware: Make sure the firmware of your Matter hub and Smart Home app is updated to support Matter.
2. Restart: Try turning off and then turning back on your device and the controller. Restart your smartphone and clear the cache of the smart home app.
3. Check IPv6: Ensure that IPv6 is activated on your router. Visit our FAQ for step-by-step guidance at https://www.tp-link.com/support/faq/1525/.
4. Enable Setup Mode: Restart your device to re-enter setup mode since Bluetooth should be turned off in 15 minutes after the device is powered up.
5. Regarding the Matter Code: The original Matter code can only be used for setup in one app (you can reuse it after a device reset). If you wish to set it up in multiple apps, generate a new code using the first app for all subsequent ones.
6. Stay on the Code-Generating Page: Do not close the pairing code-generating page in the multi-admin setup. Otherwise, this may lead to exiting the setup mode. If you accidentally close the page after generating the pairing code before adding the device to another ecosystem, you can try to reopen it. If the reopening fails, it is recommended to restart the device and try to generate the pairing code again.
7. Factory Reset Your Device: Try to factory reset the device. For most devices: Press and hold the 'Reset' button for 10 seconds. For smart bulbs: Turn the light switch off and on five times, with a 1-second pause between each action.
8. If the Matter-enabled device has already been added to another ecosystem, you will need to get a new setup code for pairing according to FAQ how to integrate your device into another ecosystem.

If the above steps did not help solve your problem, it's recommended that you try to factory reset the Matter-enabled device or use another smartphone to configure it.
