Hi everyone,
I’m experiencing an issue with Matter over Thread and have run out of ideas.
Current Setup
- Homey Pro 2026
- FRITZ!Box 7530 acting as DSL modem and DHCP server
- ASUS BT8 as Wi-Fi router
- Apple TV (latest generation) acting as Home Hub
- iPhone 15 Pro and MacBook, both running the latest software versions
- Homey Pro has already been updated to 13.3.0.RC14 for testing purposes
In addition, I have a dedicated 2.4 GHz IoT Wi-Fi network. I have already tested channels 1, 6, and 11.
Devices Already Integrated in Homey
- 1 × Zigbee door/window sensor
- 11 × IKEA Matter-over-Thread devices
- 6 × Matter-over-WiFi devices (Meross)
- 2 × Matter-over-WiFi devices (Govee)
- Several Philips Hue lights
- Ring cameras
Problem
I am trying to add two new IKEA Matter-over-Thread devices:
- 1 × MYGGBETT
- 1 × BILRESA
Apple Home
Both devices can be added to Apple Home through the Apple TV without any issues and work immediately after pairing.
Homey Pro
When trying to add the devices through the IKEA app or directly through Homey (either via iOS or Homey itself), device discovery is very unreliable. The devices are only found in approximately 1 out of 10 attempts.
If a device is discovered, the setup process starts normally. However, when Homey tries to add the device to the Thread network, the process hangs indefinitely and eventually fails with an error stating that a connection to the Thread network could not be established.
Additional Possibly Related Issue
Since the device update feature was introduced in Homey, my IKEA Matter devices are shown as having available firmware updates. However, every update attempt fails.
The download and/or installation process never progresses beyond approximately 5% before aborting.
Because of this, I suspect that the issue may be related to Homey’s Thread implementation or its communication with the Thread network rather than the individual devices themselves.
Thread Network
As far as I understand, the Apple TV is currently acting as a Thread Border Router, since all IKEA Matter-over-Thread devices can be added to Apple Home without any issues.
Could this be related to how Homey interacts with an existing Thread network, or is there a known issue with Homey joining or managing a Thread network that is already established by Apple Home?
FritzBox IPV6
ASUS BT 8 2,4 GHz Preferences
Troubleshooting Already Performed
- Updated Homey to version 13.3.0.RC14
- Reset both IKEA devices multiple times
- Tested different 2.4 GHz Wi-Fi channels (1, 6, and 11)
- Tried pairing through both iOS and directly through Homey
Since the devices can be added to Apple Home without any issues, I suspect the problem is related to Homey itself or its Matter-over-Thread implementation rather than the devices or the network in general.
Has anyone experienced something similar or has any idea what might be causing this issue?
Any help or suggestions would be greatly appreciated.
Cross-post
I have also posted this issue in a German Homey community forum (same content, in German):
If there are any updates or useful findings there, I will summarize them here as well.
