Matter device not responding or offline: how to fix it

Updated October 20, 2026 · Steps paraphrased from each platform's or maker's own help pages, linked beside each step. We have not tested these steps ourselves.

Short answer

Why is my Matter device not responding?

Start with power and the hub: restart the device (unplug it, or take its batteries out and put them back), restart your hubs and any Thread border routers, check the maker’s app for a firmware update, and keep your phone on the same Wi-Fi network as the device. If one device still does not respond, remove it from the app, reset it with its maker’s steps and add it again.(Apple: not responding; Samsung SmartThings)

When a device stops responding in every app at once, look at the hub and the router: TP-Link says a Matter device becomes unresponsive when its hub loses its connection to the router, and Google says Matter control can fail some time after setup if IPv6 is off on your home network.(TP-Link setup tips; Google: prepare for Matter)

One device, or many?

Apple gives two checklists: one for when accessories from a single maker stop responding, and a longer one for when accessories from several makers stop at once, which adds your phone’s software, your Wi-Fi network and your router.(Apple: not responding)

Apple Home: “No Response”

  1. Turn on Bluetooth on your iPhone or iPad (or on your Mac).(Apple: not responding)
  2. Restart the accessory. For a battery device, take the batteries out and put them back in.(Apple: not responding)
  3. Open the maker’s app: the accessory may need a firmware update there. If it does not respond in the maker’s app either, it may need a reset.(Apple: not responding)
  4. Unplug any third-party bridges and your home hubs (HomePod, HomePod mini, Apple TV), then plug them back in.(Apple: not responding)
  5. For Thread accessories from other makers: cut their power (or take out the batteries) for five minutes, reconnect them, and give the Thread network ten minutes to settle.(Apple: not responding)
  6. Still no response: open the accessory, scroll down to its settings and choose Remove Accessory (or remove it in the maker’s app if that option is missing), reset it with the maker’s steps and add it again.(Apple: not responding)

If several makers’ accessories stopped together, Apple adds: update your iPhone, iPad or Mac, close and reopen the Home app, join the same Wi-Fi network as your accessories, restart your modem and router, your bridges and hubs, the accessories and your phone, and check any VPN or security software. Control from away needs a home hub.(Apple: not responding)

Google Home: device offline

Google’s Matter help pages that we read cover setup rather than an offline device, but they name what control depends on. First the hub: Google Home controls Matter devices through a Matter-enabled hub on your home network, at home and from away, so check that the speaker, display, router or streamer acting as your hub is online.(Google: prepare for Matter; Google: Matter devices)

Then IPv6: Google says that without IPv6 on your home network, setup can seem to work but control and other features fail later. Check your router’s manual or ask your internet provider whether IPv6 is on.(Google: prepare for Matter)

For a Thread device, the Thread border router: on Android, Google says to check that Thread is turned on in the phone’s settings and that your border router (for example a Nest Hub or Nest Wifi Pro) is on and on the same Wi-Fi network, then restart the phone and the border router.(Android: Thread)

If a device keeps failing, Google says to contact its maker, and that you may need to factory reset it and set it up again.(Google: Matter devices)

SmartThings: device unavailable

  1. Make sure the device is within range of a Matter controller (hub), with nothing in between that could cause interference.(Samsung SmartThings)
  2. Turn the device off and on again if you can, and restart the SmartThings app.(Samsung SmartThings)
  3. Check its power: Samsung notes that some battery devices start failing before the battery reads zero, and that a wired device should be installed to its maker’s specifications.(Samsung SmartThings)
  4. Turn the Matter controller off and on again.(Samsung SmartThings)
  5. Remove the device and add it again: touch and hold it on the Favorites or Devices tab and choose Remove.(Samsung SmartThings; SmartThings: devices)

If you still cannot control it reliably, Samsung says to contact Samsung support from the menu in the SmartThings app.(Samsung SmartThings)

Alexa

We do not request Amazon’s own help pages, so this section uses TP-Link’s guides for its Matter devices, which apply to Alexa as to the other apps: keep the Echo and the device on the same main network (not a guest or IoT network or another VLAN), update the device’s firmware in the maker’s app, and remember that the device stops responding when the hub loses the router, until it reconnects.(TP-Link troubleshooting; TP-Link setup tips)

For a Thread device, the Echo or eero also has to be a Thread border router. Amazon’s developer documentation lists Echo (4th Gen); Echo Hub; Echo Show 10 (3rd Gen); Echo Show 15 (2nd Gen); Echo Show 21; Echo Dot Max; Echo Show 8 (3rd Gen, 2025 release) and Echo Studio (2025 release) as Echo devices with one built in, plus several eero routers.(Amazon)

Home Assistant: device unavailable

For devices that become unavailable at random, Home Assistant gives the network as the cause: Matter needs local IPv6 and multicast traffic to pass freely, and VLANs, multicast filtering and faulty IGMP snooping get in the way. Keep Wi-Fi Matter devices and border routers on the same network as Home Assistant, and keep the network as simple as you can.(Home Assistant: Matter)

For Thread devices that drop off, Home Assistant points to Wi-Fi interference: Thread uses the same 2.4 GHz band as Wi-Fi, and moving the Thread network to channel 25 or 26 can help. Some devices do not follow a channel change and must be added again.(Home Assistant: Thread)

When the maker’s app is the cause

Eve’s advice for devices that show “not responding” after a while: unplug them or take the batteries out for a minute, restart your hubs and Thread border routers and wait five minutes, restart your phone, and do not use a VPN or iCloud Private Relay.(Eve)

Some maker apps can break the Matter connection. Govee says that switching a device to another network in the Govee Home app turns its Matter function off, so you reset it and add it again. TP-Link says removing a device in the Tapo or Kasa app factory resets it, so it then shows as unresponsive in every other app.(Govee; TP-Link setup tips)

Frequently asked questions

What does No Response mean in Apple Home?

Apple shows it next to an accessory that is not responding in the Home app. Apple’s fixes start with turning Bluetooth on, restarting the accessory, the hubs and any bridges, and checking the maker’s app for a firmware update; if that fails, remove the accessory, reset it and add it again.

Why do my Matter devices go offline in Google Home?

Check the hub first: Google Home controls Matter devices through a Matter-enabled hub on your network. Then check IPv6, which Google says Matter needs to keep working. Thread devices also need a working Thread border router.

Why did my Matter device stop working in every app at once?

TP-Link says a Matter device becomes unresponsive when its hub loses its connection to the router, and that removing a device in its maker’s app can factory reset it, which makes it unresponsive in all the other apps.

Should I reset a Matter device that is not responding?

Only as a last step. Apple, Samsung and Google list removing the device, resetting it with its maker’s steps and adding it again after the restarts and checks have not helped. Keep the setup code before you reset.
