First determine whether the Matter device will not pair or whether it paired before and has stopped responding. For setup failures, check power, Bluetooth, platform support and Wi-Fi compatibility. For a device that went offline, check its current network, router settings and controller before removing or resetting it.
Start by identifying when the problem began
Matter devices can connect through Wi-Fi, Ethernet or Thread. This guide applies to devices that use Wi-Fi; 2.4 GHz and 5 GHz advice does not apply to a Thread device. If you are unsure which connection your model uses, check its instructions.

- It will not add: Look for setup or commissioning problems, such as a device that is not powered, a phone that cannot discover it, or a network the accessory does not support.
- It was added but now says “No Response”: Check whether the accessory is powered and reachable on its current network, and whether the controller or home hub is online.
- Only one brand or accessory is affected: Start with that device’s power, firmware and manufacturer app.
- Several brands stopped working together: Check the shared router, hub, phone network, VPN or security software before resetting individual devices. Apple recommends checking the router or modem and VPN or third-party security software when accessories from multiple manufacturers fail together (Apple’s Home troubleshooting guidance).
If the device still responds in the manufacturer’s app but not in the smart-home app, that points toward a difference between the app, controller and local-network path; it does not by itself establish the cause. Matter commissioning is the process of discovering and setting up a device, so a device that was already commissioned needs a different diagnosis from one that cannot be added (Matter 1.3 Core Specification, published April 17, 2024).

If the device will not add
Check basic setup conditions
- Make sure the accessory is powered on and follow its maker’s instructions for putting it into setup mode. If the app reports “Unable to add to home,” Apple advises checking power, proximity, hubs and the maker’s reset instructions (Apple Home setup troubleshooting).
- Keep the phone near the accessory and router while setting up if the device maker recommends it. Enable Bluetooth during setup when the platform or manufacturer requires it. Google Home’s Matter setup requirements include Bluetooth Low Energy (BLE) 4.2 or later and a Matter-enabled hub (Google Home Matter setup requirements).
- Confirm the model is supported by the smart-home platform you are using, and update the app, phone/controller software and accessory firmware where updates are available.
- If Alexa reports “No new devices found,” check the device list before pairing again. Amazon notes that some devices may have connected automatically through Frustration-Free Setup (Amazon Alexa Matter troubleshooting).
Verify Wi-Fi compatibility before changing the router
Some Wi-Fi Matter devices have specific band requirements. Apple says some accessories do not support 5 GHz; if Home reports that the “network is incompatible,” check the model’s instructions and 2.4 GHz support (Apple Home troubleshooting). For Matter Wi-Fi devices used with Alexa, Amazon specifies that the device must use the same 2.4 GHz network as a compatible Matter controller (Amazon Alexa Matter troubleshooting).

These are platform- and model-specific directions, not a rule that every Matter device needs a separate Wi-Fi name. Before splitting bands, renaming a network or changing router settings, consult the accessory’s manual and the smart-home platform’s current instructions.
If an added device has stopped responding
Check power, controller and network status
- Confirm the accessory has power and that its status lights or manufacturer app do not indicate a separate fault.
- Check that the phone and home hub or Matter controller are online and using the expected home network. Restart the accessory and controller or hub, then try control again.
- Check for app and firmware updates. If several accessories from different makers are affected, reopen the Home app if you use Apple Home, then restart the router or modem and check whether a VPN or third-party security app is interfering (Apple Home troubleshooting).
For Google Home, check IPv6
Google says IPv6 must be enabled on the home wireless network for Matter to work properly. It warns that setup may appear to succeed without IPv6, while control or other functionality later fails (Google Home Matter setup requirements). If you cannot find the IPv6 setting or are unsure whether your service supports it, consult the router manual or your internet provider rather than changing unrelated network settings.

Check for a guest network or device isolation
A guest Wi-Fi network or access point (AP) or client isolation setting can block local communication between devices. Google identifies AP isolation as a potential barrier and recommends disabling it when it prevents smart devices from communicating with other devices on the network (Google guidance on router compatibility with Nest products). Router labels differ; consult the router maker’s instructions and consider the security implications before changing isolation settings.
Recommended Free Tools
Restart before removing or resetting

Do not use Wi-Fi band changes as a fix for Thread. Apple gives a separate recovery step for third-party Thread accessories: disconnect power for five minutes, reconnect, then wait ten minutes for the Thread network to stabilize (Apple Home troubleshooting). That timing is for the specified Thread recovery case, not a Wi-Fi device.
